Aug 2, 2022 · It was noticed that the production was increased by 6.0% in the seeds which was inoculated by A. chroococcum as compared to the other samples. The inoculated plant also shows increment in weight of wet root by 18%, weight of dry roots by 31%, weight of wet plant as a whole by 13%, number of leafs and branches by 27% and the weight of dry plant
The scale of manufacturing, often designated by the scale of the production fermenter or bioreactor, has a major impact on the cost of manufacturing. Generally, manufacturing labor requirements increase more slowly than volume increases. For example, a 2000 L bioreactor does not require ten times as many operators to run as a 200 L bioreactor does.
Mar 25, 2021 · The constant increase in the amount of food waste accumulating in landfills and discharged into the water reservoirs causes environment pollution and threatens human health. Solid and liquid food wastes include fruit, vegetable, and meat residues, alcohol bard, and sewage from various food enterprises. These products contain high concentrations of biodegradable organic compounds and represent
Jan 18, 2021 · Co-fermentation, the simultaneous fermentation of two or more waste, is an opportunity for wastewater treatment plants (WWTP) to increase the yields of sludge mono-fermentation.
Sep 7, 2023 · The use of yeasts for the production of proteases has increased in demand in recent years. Y. lipolytica has been reported as a strain with high yields of protease production. This work aimed to evaluate the impact of pH and temperature on the production of proteases using Y. lipolytica in solid-state fermentation (SSF). Soybean, canola meal, cottonseed meal, and sesame meal wastes were used
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.
Jan 1, 2018 · The commercial production of ethanol involves several steps: feedstock preparation, pretreatment, inoculum development, fermentation, and downstream processing. The following sections describe the unit processes involved in ethanol production, with a general process flow diagram presented in Fig. 5.4.
Aug 17, 2023 · Advanced fermentation techniques are also introduced, in-cluding cell immobilization, co-culture, simultaneous saccharification and co-fermentation. Genetic and metabolic engineering plays an important role in adapting wild-type strains to specific agricultural waste to increase LA production.
Jun 15, 2021 · A novel combination of two stage AD and ED increased biofuels production from FW. • Using ED in a hydrogen fermenter increased the hydrogen yield by factor of 1.9. • ED had a positive effect on patterns of FW utilization and VFA production. • Using ED and two-stage AD to treat FW increases overall bioenergy recovery by 77.1%.
Jan 31, 2024 · About the assay of higher H 2 production, in this experimental condition a gCaCO 3.the g −1 CHO ratio of 0.45 was obtained, which enabled operational pH stability that conditioned the predominance of metabolic pathways for hydrogen production so that considering the co-fermentation of citrus waste is recommended to maintain the pH in the
Biological hydrogen is produced via dark fermentation of organic wastes [ 4 ]. Fermentative hydrogen production is carried out by anaerobic bacteria that ferment organic compounds to volatile fatty acids (VFAs), alcohols, carbon dioxide, and hydrogen (Fig. 2.1 ).
May 29, 2023 · In the present study, a novel strategy for the effective production of hydrolase via fermentation of food waste was developed to improve methane production from anaerobic digestion of waste activated sludge (WAS). Via the pre-fermentation of food waste, hydrolase could be efficiently enriched and then directly used to enhance sludge hydrolysis with no need for extraction and purification of
Mar 12, 2024 · Abstract. Acidogenic fermentation is an emerging biotechnology that allows for the utilization of food waste as a feedstock to produce high-value products such as short-chain fatty acids (SCFAs), effectively offering a tangible solution for food waste management as well as resource recovery.
May 5, 2021 · Fermentation is now widely used to produce alcoholic beverages, bread and pastry, dairy products, pickled vegetables, soy sauce and so on. More recent advances based on genomics and synthetic biology include precision and biomass fermentation to produce specific compounds for the food and chemical industry or medicinal use.
