“…Peptones are defined as the water soluble mixture of proteins, peptides, free amino acids, and small amounts of nucleotides and carbohydrates that are not coagulable by heat, and are obtained by the hydrolysis (thermal, chemical, or enzymatic) of animal, vegetal, or microbial substrates. They are the most important and expensive source of organic nitrogen in the commercial media for the cultivation of microorganisms [40,41,42]. Therefore, inexpensive sources of peptones from food wastes are in high demand [43].…”

The objective of this report was to investigate the isolation and recovery of different biocompounds and bioproducts from wastes (skins and heads) that were obtained from five species discarded by fishing fleets (megrim, hake, boarfish, grenadier, and Atlantic horse mackerel). Based on chemical treatments, enzymatic hydrolysis, and bacterial fermentation, we have isolated and produced gelatinous solutions, oils that are rich in omega-3, fish protein hydrolysates (FPHs) with antioxidant and antihypertensive activities, and peptones. FPHs showed degrees of hydrolysis higher than 13%, with soluble protein concentrations greater than 27 g/L and in vitro digestibilities superior to 90%. Additionally, amino acids compositions were always valuable and bioactivities were, in some cases, remarkable. Peptones that were obtained from FPHs of skin and the heads were demonstrated to be a viable alternative to expensive commercial ones indicated for the production of biomass, lactic acid, and pediocin SA-1 from Pediococcus acidilactici.

“…45,46 However, its performance is highly dependent on the specific peptide (length and sequence) and free amino acid profiles. 46,51 Moreover, YE was included despite showing a significant effect for avoiding nitrogen starvation; it is also considered the best organic nitrogen source for SCP production compared to other nitrogen sources (i.e., PE, beef extract, malt extract, soybean, tryptone, gelatin, and casein). 29 Consequently, the variables DAP and PE were not studied in the full factorial design, with only CWW and YE being selected for further optimization experiments.…”

Background Coffee production is an important agro‐industrial activity in several countries worldwide. However, during wet processing of coffee beans, substantial quantities of wastewater effluents are generated and discharged into nearby water systems, negatively impacting ecosystems. A compelling biotechnological alternative involves the use of nutrients contained in wastewater (e.g., sugars, proteins, and salts) to produce value‐added molecules–such as single‐cell protein (SCP) using the yeast Candida sorboxylosa–with high potential for use as animal feed. Results Yeast isolated from the feces of ring‐tailed coatis showed a positive assimilation of reducing sugars (glucose, mannose, and fructose). Efficient reuse of coffee wastewater (CWW) for SCP production was achieved via the statistical design of experiments (DoE) technique. The bioprocess was standardized in a medium culture composed of 87.5% (v/v) CWW, and of 1.38 and 7.24 g/L yeast extract (YE) and ammonium sulfate [(NH4)2SO4], respectively, resulting in a high SCP yield of approximately 38%. Conclusion The reuse of CWW shows potential as a low‐cost component for SCP production that can ultimately reduce the environmental impact of wastewater effluent by circumventing its release into river systems. The bioprocess developed in this study presented certain advantages, including high volumes of CWW with only YE and (NH4)2SO4 supplementation, and without requiring additional components to correct the pH of the medium. Therefore, it is highly feasible to apply this bioprocess in close proximity to coffee‐processing agrobusinesses, thus generating an alternative source of income for Peruvian coffee‐producing communities. © 2022 Society of Chemical Industry (SCI).

“…Finally, it must be mentioned that FPHs could be also used as substrate to obtain peptones (mixture of polypeptides and free amino acids) useful as ingredient of culture media for microbial growths (Pleissner and Venus, 2016). A great percentage of microbial bioproduction costs are due to the price of peptones (Djellouli et al, 2017;Shi et al, 2018) being the search of new protein fractions from food wastes an essential research issue (Pleissner and Venus, 2016).…”
