Feb 20, 2024 · Lactic acid is an important industrial precursor; however, high substrate costs are a major challenge in microbial fermentation-based lactic acid production. Coffee waste is a sustainable feedstock alternative for lactic acid production via microbial fermentation.
Apr 20, 2020 · The experiment was composed of two parts. One was the fermentation liquid production through food waste fermentation. The other one was the denitrification of simulated secondary wastewater using the produced fermentation liquid as carbon source. Both of them were operated in SBR with each 1 L working volume.
Jul 25, 2021 · Especially, research regarding waste utilization through photo-fermentation has been carried out, to emphasize the application ability of this method in waste environment. Table 12 shows that the production rate of biohydrogen produced using microalgal strains varies from 0.8 to 9.2 mL/(L*h).
Sep 1, 2018 · In this study, high relative abundance of phyla Actinobacteria and Proteobacteria in all samples resulted in high hydrolysis extent as these phyla are highly related to hydrolytic microbial population (Chen et al., 2017a). H 2 production was attributed to the high relative abundance of Clostridia in all samples (Liu et al., 2011).
Global interest towards lactic acid production has recently significantly increased because lactic acid can be used as raw material for the production of polylactic acid (PLA), a polymer used in biodegradable plastics for its special, environmentally-friendly properties. However, the high production costs have hindered the large-scale application of PLA due to the high price of lactic acid
Aug 9, 2019 · Solid-state fermentation (SSF) is, by definition, a technology carried out in absence or near absence of free water. Therefore, it allows the use of solid materials as substrates for further biotransformation. SSF has gained attention in the last years being reported as a promising eco-technology that allows obtaining bioproducts of industrial interest using solid biomass (wastes and by
39.4.2.3 Fermentation of food wastes. The compositional variation is one of the challenges in food waste fermentation. Recently, Poe et al. (2020) studied the influence of compositional variation of food waste on butanol production through fermentation. They collected dining hall food waste weekly for 16 weeks.
Mar 1, 2024 · Through adding high-density polyethylene (HDPE), PP, and PS to an anaerobic fermentation system for food waste, 47 % increase in the final VFAs production was observed, which caused by the porous structure of PS that favors the immobilization and growth of bacteria [8]. For HDPE and PP, the acid production increased by 28 % and decreased by 6 %
Sep 20, 2022 · The recombinant yeast expressed the GLA up to 19.2% (72 mg/g) of total fatty acids. GLA production of recombinant yeast was studied in a fermenter by oil waste for 5 days, and results detected 6.3 g/l lipid, and 103 mg/g GLA was produced in 72 h. The present study may provide an opportunity to develop an alternative host for manufacturing GLA
6 days ago · At this stage, the continuous fermentation of VFAs was stably established, and production finally reached 60.3 g/L. Wainaina et al. (2020) adopted immersed AnMBRs to produce VFAs from food waste, and the production reached 37.0 g/L at a pH of 5.5 with an OLR of 10 g-VS/L/d.
Jan 1, 2022 · With respect to food waste valorization, biomass fermentation, i.e. production of microbial biomass using food waste as feedstock is particularly interesting as it enables the efficient conversion of a variety of agri-food waste into high protein microbial biomass for food application (Teng et al., 2021). 5.4.4.
Mar 26, 2021 · On the other hand, in medium- and high-income countries, food is lost or discarded in the final steps, by retailers and consumers, due to the high productivity and quality standards required by the market . As a result, many resources are lost in terms of land, water, and nutrients, and therefore the production, processing, manufacturing, and
Apr 15, 2013 · It was concluded that the iron, nickel and cobalt limitation can decrease the process stability and gas production rate in thermophilic digester with high solid food waste substrate, and the addition of 10 mg L −1 Fe 2+, 1 mg L −1 Co 2+ and 1 mg L −1 Ni 2+ approximately every 45 days can result in successful methane fermentation at the
Jun 1, 2022 · A model FW was prepared according to Capson-Tojo et al. (2017) to ensure the relative stability and reproducibility of the substrate properties during the experiments. This substrate, composed of fruits and vegetables (25.9% apple and 25.9% lettuce), carbohydrates (25.9% potato, 4.8% wheat meal and 6.2% bread), meat (4.1% chicken and 4.1% beef), dairy products (1.9% yoghurt) and pastries (1.5%
