Since the sources of AWs are diverse, they can often be potentially hazardous and detrimental to the terrestrial and aquatic ecosystems. The only solution that appears to meet futuristic needs is the use of renewable energy. Similarly, dewatering of algal slurry is not required unlike in the expeller press method and this contributes to reduction in processing costs. Biofuel is defined as liquid, solid, or gaseous fuel produced by conversion of biomass such as bioethanol from sugar cane or corn, charcoal or woodchips, and biogas from anaerobic decomposition of wastes (OECD, 2002). A sustainable alternative is the yeast production from the ethanol residuals. 1, S91S95. 91, 171182. This is especially true for piles lacking adequate porosity for effective gas exchange.

Selection of marine yeasts for the generation of single cell protein from prawn-shell waste. The amount of yard wastes composted has increased dramatically over the past three decades with the vast majority now being composted instead of landfilled (Fig. The economic and technical viability has not been worked out so far and it is too early to predict that this method is one of the better methods for algal oil extraction. Therefore, a considerable quantity of fertilizer will be required for the growth of algae. Usually, the oil recovery is in the range of 7075%. Genetic-engineering approaches for enhanced production of biodiesel fuel from microalgae. Energy Res. The World Health Organization is urging the development. (2002). Addition of enzymes such as cellulase and trypsin to the microalgal biomass will enable the intracellular lipids to be extracted easily after degradation of tough polymers present on the cell surface structures (Taher et al., 2014). The degradation of PAHs was accompanied by the production of fungal extracellular laccase and versatile peroxidase, whose activities were higher in the co-culture than they were in the monocultures. Use of Bacillus subtilis isolates from Tua-nao towards nutritional improvement of soya bean hull for monogastric feed application. Morphological characteristics could also potentially be engineered to provide specific organoleptic properties. A., Rozlan, N. F. M., and Al-Gheethi, A. The main barrier is in the introduction of SCP from new species, which generate academic and patent interest, but which are difficult to bring into the market. Industrial Crops and Products The fungal biomass provides a texture that resembles meat products. Biotechnol. In this method, wet algal biomass is processed for the extraction of lipids followed by transesterification to obtain biodiesel, and therefore, it gains significance in the field of algal biofuel R&D.

Production of Food. 152, 110. Upon cooling, the aqueous phase and solids were separated under light vacuum condition using an appropriate filter (934-AH filter paper; Whatman). Both the organic phases containing the lipid extract can be vacuum dried to drain off the excess solvent. First, unlike other industrial waste minimization strategies, organic waste reduction is often accompanied by incineration or burning of organic waste (Prez-Martnez etal.,2019). L.T. Lett. Rapid method for the determination of lipid from the green alga Botryococcus braunii. These are typically non-animal based, environmentally friendly processes, but may include novel processes such as the production of cultured meat, in which meat protein is more efficiently produced in vitro rather than by growing an entire animal (Kadim et al., 2015). As with SCP from fungi, other developments in the production of bacterial SCP focus on upgrading various waste substrates or valorisation of waste water treatment. Food Sci. S.C. Bhatia, in Advanced Renewable Energy Systems, 2014. doi: 10.1016/0377-8401(76)90003-1. It should be noted that not all animals are regarded the same in all regions, thus pet food is regulated as feed in some areas, but not in others. AW is a general term used to describe waste produced on a farm through various farming activities. Methyl-tert-butyl ether (MTBE) was used as a solvent for the extraction of lipids, and this method provides the most accurate lipidome profile. Spent brewer's yeast (Saccharomyces cerevisiae) have been sold for more than a century in yeast extracts such as Marmite (Unilever and Sanitarium Health Food), Vegemite (Bega Cheese Ltd.), Cenovis (Gustav Gerig AG), and Vitam-R (VITAM Hefe-Produkt GmbH). J. Chromatogr. J Food Sci. According to Freije (2015), the presence of hydrocarbons on soil-water interface has major public health repercussions. In Denmark from 1990 to 1992, workers who collected organic waste experienced eye and skin irritation, nausea, vomiting, and diarrhea. Hypo-osmotic shock is a procedure commonly used for the extraction of intracellular substances from microorganisms. The production of biofuel from algae at a large scale requires lot of equipment, tools, energy, water, and nutrients for each step. Gao, H., and Xu, J. G. (2015). For example, DuPont has genetically engineered a yeast to produce long-chain omega-3 fatty acids, which are essential to human health (Xie et al., 2015). Table24.3 lists some of the materials commonly used as feedstocks for composting, and Table24.4 lists the nutrient contents of selected compostable substrates. The results indicated that 45.5gL1 of ethanol was achieved after 30hours [10]. Life-cycle assessment (LCA) of the biofuel production process has been performed in a number of studies, are discussed to comprehend the sustainability of different production pathways. The INNOLIPA genotyping system was used to classify HPV which was neither type 16 or 18.

Toxins may be extracellular (exotoxins) or cell bound (endotoxins). 7 the highest amount of ethanol was produced in the United States with the value of 15,250 million gallons in 2016. This article describes rigorously different characteristics of organic waste and obstacles with regard to recalcitrant nature besides various pretreatment techniques (physical, chemical, and biological) separately and in combination for effortless digestion and improved biogas production. Int. Compiled from multiple sources. The feasibility of extracting lipids using microwave irradiation was first reported in the mid-1980s (Ganzler et al., 1986). rev. Therefore, differences in structure and chemical composition lead to a different pretreatment method that distinguishes JA stalks from others, and also makes JA stalks alone [53] or together with its tubers to be promising materials for ethanol production in industries. Feedstock processing steps may differ according to the ready availability of reducing sugars, that is, the broth extracted from sugar-rich crops, such as sugarcane, beet, and sweet sorghum, may be directed employed in fermentation, whereas starch-rich (e.g., corn, cassava, and barley) and cellulosic materials require pretreatment steps (Fig. These microorganisms can be divided in to two groups: mesophilic and thermophilic. Production of biofuels from algae involves two distinct stages: upstream processing and downstream processing. 6, 103116. Normalized viral load (NVL) was calculated using a COBAS 4800 system.

Along with squalene, vitamin D and nutritional oils, Nucelis Inc. is developing high protein flour from the yeast Yarrowia. Microbiol. Trends Food Sci. Many products, such as bags, jars, containers, and drums, are reusable; thus, instead of discarding them, reusing them can save a significant amount of solid waste. Waste from the food is a challenge to the environment all over the globe, hence there is need to be recycled. Phys. Currently, organic waste streams are not used as e-donor for high-rate sulfate-reducing bioreactors for many reasons. Corn oil is edible and its use in India for production of ethanol is not economically feasible. These processes are based on chemical reactions carried out thanks to the exploitation of enzymes, mushrooms, and microorganisms. International Feed Industry Federation, July 12, 2013. Bioresour.

Some waste disposal methods are dangerous to the environment and should not be encouraged, including open dumps, animal feed, incineration, deep well injection, sanitary landfills, and river and ocean dumping (Abdel-Shafy and Mansour,2018; Alam and Ahmade,2013; Xie etal.,2017). In SSF the enzymatic degradation of cellulose is combined with the fermentation of glucose obtained from hydrolysis. (2011) and Table 3 provides a list of more recent research on bacterial SCP. This in turn leads to the electroporation effect, which further opens up the cell membrane, thereby rendering efficient extraction of intracellular metabolites (Rosenberg and Bogl, 1987). 23, 471499. Biochem. Much of the current research focuses on the use of waste substrates such as sugarcane bagasse (e.g., Penicillium janthinellum with 46% protein, Rao et al., 2010), brewery's spent grains, hemicellulosic hydrolysate (e.g., Debaryomyces hansenii, White et al., 2008; Kluyveromyces marxianus, Aggelopoulos et al., 2014), whey (mixed yeast cultures, Yadav et al., 2014, 2016; K. marxianus, Aggelopoulos et al., 2014), and mixtures of other common food industry wastes such as orange and potato residues, molasses, and malt spent rootlets (K. marxianus, Aggelopoulos et al., 2014). It will, thus, require innovative dimensions of political will and institutional cooperation to achieve the solution to this complex challenge. Authorisation is required before sale of new feed or additives (Smedley, 2013). Thus, microwave technology has allowed the development of rapid, safe, and economical methods for extracting lipids and does not require dewatering of algal biomass (Pare et al., 1997). Lignin biodegradation by the ascomycete Chrysondia sitophila. Chem.

Endogenous RNA degrading enzymes (ribonucleases) can be exploited in degradation of RNA, after activation with heat treatment (6070C) as used in the production of Quorn (Anderson and Solomons, 1984). 114, 457465. An innovative and alternate approach of using osmotic pressure is considered an ecological and cost-effective way to compete with other extraction methods (Adam et al., 2012). However, the main challenge of using lignocellulosic materials for biofuel production. Anal. M.K. Hydrogen from biomass appears today an interesting alternative to electrolysis route. M. Moo-Young and K. F. Gregory (London: Elsevier Applied Science), 2732. Since the sources of AWs are diverse, they can often be potentially hazardous and detrimental to the terrestrial and aquatic ecosystems. The only solution that appears to meet futuristic needs is the use of renewable energy. Similarly, dewatering of algal slurry is not required unlike in the expeller press method and this contributes to reduction in processing costs. Biofuel is defined as liquid, solid, or gaseous fuel produced by conversion of biomass such as bioethanol from sugar cane or corn, charcoal or woodchips, and biogas from anaerobic decomposition of wastes (OECD, 2002). A sustainable alternative is the yeast production from the ethanol residuals. 1, S91S95. 91, 171182. This is especially true for piles lacking adequate porosity for effective gas exchange. Pruteen contained up to 70% protein and was used in pig feed (Johnson, 2013). Sustain. Table 4, lists companies reported to produce or to have an interest in SCP, with website and patent information provided when available. Mycologist 18, 1720. Selection of marine yeasts for the generation of single cell protein from prawn-shell waste. The amount of yard wastes composted has increased dramatically over the past three decades with the vast majority now being composted instead of landfilled (Fig. The economic and technical viability has not been worked out so far and it is too early to predict that this method is one of the better methods for algal oil extraction. Therefore, a considerable quantity of fertilizer will be required for the growth of algae. Usually, the oil recovery is in the range of 7075%. Genetic-engineering approaches for enhanced production of biodiesel fuel from microalgae. Energy Res. The World Health Organization is urging the development. (2002). Addition of enzymes such as cellulase and trypsin to the microalgal biomass will enable the intracellular lipids to be extracted easily after degradation of tough polymers present on the cell surface structures (Taher et al., 2014). The degradation of PAHs was accompanied by the production of fungal extracellular laccase and versatile peroxidase, whose activities were higher in the co-culture than they were in the monocultures. Use of Bacillus subtilis isolates from Tua-nao towards nutritional improvement of soya bean hull for monogastric feed application. Morphological characteristics could also potentially be engineered to provide specific organoleptic properties. A., Rozlan, N. F. M., and Al-Gheethi, A. The main barrier is in the introduction of SCP from new species, which generate academic and patent interest, but which are difficult to bring into the market. Industrial Crops and Products The fungal biomass provides a texture that resembles meat products. Biotechnol. In this method, wet algal biomass is processed for the extraction of lipids followed by transesterification to obtain biodiesel, and therefore, it gains significance in the field of algal biofuel R&D.

Production of Food. 152, 110. Upon cooling, the aqueous phase and solids were separated under light vacuum condition using an appropriate filter (934-AH filter paper; Whatman). Both the organic phases containing the lipid extract can be vacuum dried to drain off the excess solvent. First, unlike other industrial waste minimization strategies, organic waste reduction is often accompanied by incineration or burning of organic waste (Prez-Martnez etal.,2019). L.T. Lett. Rapid method for the determination of lipid from the green alga Botryococcus braunii. These are typically non-animal based, environmentally friendly processes, but may include novel processes such as the production of cultured meat, in which meat protein is more efficiently produced in vitro rather than by growing an entire animal (Kadim et al., 2015). As with SCP from fungi, other developments in the production of bacterial SCP focus on upgrading various waste substrates or valorisation of waste water treatment. Food Sci. S.C. Bhatia, in Advanced Renewable Energy Systems, 2014. doi: 10.1016/0377-8401(76)90003-1. It should be noted that not all animals are regarded the same in all regions, thus pet food is regulated as feed in some areas, but not in others. AW is a general term used to describe waste produced on a farm through various farming activities. Methyl-tert-butyl ether (MTBE) was used as a solvent for the extraction of lipids, and this method provides the most accurate lipidome profile. Spent brewer's yeast (Saccharomyces cerevisiae) have been sold for more than a century in yeast extracts such as Marmite (Unilever and Sanitarium Health Food), Vegemite (Bega Cheese Ltd.), Cenovis (Gustav Gerig AG), and Vitam-R (VITAM Hefe-Produkt GmbH). J. Chromatogr. J Food Sci. According to Freije (2015), the presence of hydrocarbons on soil-water interface has major public health repercussions. In Denmark from 1990 to 1992, workers who collected organic waste experienced eye and skin irritation, nausea, vomiting, and diarrhea. Hypo-osmotic shock is a procedure commonly used for the extraction of intracellular substances from microorganisms. The production of biofuel from algae at a large scale requires lot of equipment, tools, energy, water, and nutrients for each step. Gao, H., and Xu, J. G. (2015). For example, DuPont has genetically engineered a yeast to produce long-chain omega-3 fatty acids, which are essential to human health (Xie et al., 2015). Table24.3 lists some of the materials commonly used as feedstocks for composting, and Table24.4 lists the nutrient contents of selected compostable substrates. The results indicated that 45.5gL1 of ethanol was achieved after 30hours [10]. Life-cycle assessment (LCA) of the biofuel production process has been performed in a number of studies, are discussed to comprehend the sustainability of different production pathways. The INNOLIPA genotyping system was used to classify HPV which was neither type 16 or 18. A novel approach for environmentally friendly production of single cell protein from petrochemical wastewater using a halophilic microorganism in different conditions. Bioresour. Furthermore, it does not require the addition of beads or chemicals, which have to be removed later in the process, which in turn will incur more cost (Harrison, 1991). Only between 2011 and 2012, the increase of venture capital and private equity business investment in the sector of waste-to-energy together with biomass has enumerated an increase of 186%, summing up to a total investment of USD 1 billion. doi: 10.1016/j.biortech.2010.04.001, Zhang, H.

Toxins may be extracellular (exotoxins) or cell bound (endotoxins). 7 the highest amount of ethanol was produced in the United States with the value of 15,250 million gallons in 2016. This article describes rigorously different characteristics of organic waste and obstacles with regard to recalcitrant nature besides various pretreatment techniques (physical, chemical, and biological) separately and in combination for effortless digestion and improved biogas production. Int. Compiled from multiple sources. The feasibility of extracting lipids using microwave irradiation was first reported in the mid-1980s (Ganzler et al., 1986). rev. Therefore, differences in structure and chemical composition lead to a different pretreatment method that distinguishes JA stalks from others, and also makes JA stalks alone [53] or together with its tubers to be promising materials for ethanol production in industries. Feedstock processing steps may differ according to the ready availability of reducing sugars, that is, the broth extracted from sugar-rich crops, such as sugarcane, beet, and sweet sorghum, may be directed employed in fermentation, whereas starch-rich (e.g., corn, cassava, and barley) and cellulosic materials require pretreatment steps (Fig. These microorganisms can be divided in to two groups: mesophilic and thermophilic. Production of biofuels from algae involves two distinct stages: upstream processing and downstream processing. 6, 103116. Normalized viral load (NVL) was calculated using a COBAS 4800 system. Applied Microbiology is an international, peer-reviewed, open access journal on application of microorganisms published quarterly online by MDPI.. Open Access free for readers, with article processing charges (APC) paid by authors or their institutions. Along with squalene, vitamin D and nutritional oils, Nucelis Inc. is developing high protein flour from the yeast Yarrowia. Microbiol. Trends Food Sci. Many products, such as bags, jars, containers, and drums, are reusable; thus, instead of discarding them, reusing them can save a significant amount of solid waste. Waste from the food is a challenge to the environment all over the globe, hence there is need to be recycled. Phys. Currently, organic waste streams are not used as e-donor for high-rate sulfate-reducing bioreactors for many reasons. Corn oil is edible and its use in India for production of ethanol is not economically feasible. These processes are based on chemical reactions carried out thanks to the exploitation of enzymes, mushrooms, and microorganisms. International Feed Industry Federation, July 12, 2013. Bioresour.

UniBio A/S, Denmark is an SME that owns rights to a unique fermentation technologythe U-Loop technology, which enables natural gas to be converted into a high protein productUniProtein. Bioresour. Am. More recently developed products are often formulated as dry powders or flours, which are intended to be mixed with other ingredients to create products in which the individual components are not perceived. Much of the recent interest in SCP has focused on the valorisation of side streams by using microorganisms to improve their protein content, which can then be used in animal feed. Biotechnol. Biofuel is an environment-friendly alternative to fossil fuel, but there are many problems and drawbacks in the production and commercialization of biofuel from algae. 101, S75S77. J. Fungal SCPs offer the advantages of familiarity, with well-established processing approaches, and availability. Use of ionic liquid for algal lipid extraction is an innovative and emerging alternative pre-treatment technology. Fig. (2010). Enzyme activities were spectrophotometrically measured with test substrates. doi:10.1016/j.biortech.2011.05.064, Weerheim, A. M., Kolb, A. M., Sturk, A., and Nieuwland, R. (2002). Some waste disposal methods are dangerous to the environment and should not be encouraged, including open dumps, animal feed, incineration, deep well injection, sanitary landfills, and river and ocean dumping (Abdel-Shafy and Mansour,2018; Alam and Ahmade,2013; Xie etal.,2017). In SSF the enzymatic degradation of cellulose is combined with the fermentation of glucose obtained from hydrolysis. (2011) and Table 3 provides a list of more recent research on bacterial SCP. This in turn leads to the electroporation effect, which further opens up the cell membrane, thereby rendering efficient extraction of intracellular metabolites (Rosenberg and Bogl, 1987). 23, 471499. Biochem. Much of the current research focuses on the use of waste substrates such as sugarcane bagasse (e.g., Penicillium janthinellum with 46% protein, Rao et al., 2010), brewery's spent grains, hemicellulosic hydrolysate (e.g., Debaryomyces hansenii, White et al., 2008; Kluyveromyces marxianus, Aggelopoulos et al., 2014), whey (mixed yeast cultures, Yadav et al., 2014, 2016; K. marxianus, Aggelopoulos et al., 2014), and mixtures of other common food industry wastes such as orange and potato residues, molasses, and malt spent rootlets (K. marxianus, Aggelopoulos et al., 2014). It will, thus, require innovative dimensions of political will and institutional cooperation to achieve the solution to this complex challenge. Authorisation is required before sale of new feed or additives (Smedley, 2013). Thus, microwave technology has allowed the development of rapid, safe, and economical methods for extracting lipids and does not require dewatering of algal biomass (Pare et al., 1997). Lignin biodegradation by the ascomycete Chrysondia sitophila. Chem. In the following sections, recent developments in the intensification of algal processes at each step of the algal biofuel production chain are presented. To tackle with environmental concerns, creation of a pollution-free green environment is the need of the hour. doi:10.1016/S0021-9673(01)94714-4, Gavrilescu, M., and Chisti, Y. N. Biotechnol. (2011).
