What is a fermenter? Methane fermentation and anaerobic digestion are used to produce biogas from organic waste and leftovers. They are both operated under an anaerobic
2022/2/8/ · Compared with other culture , solid-state fermentation has the following advantages: (1) the medium is simple and widely available, mostly inexpensive natural substrates such as biomass straw, etc. (2) Low investment and low energy consumption. The technology is simple. (3) The yield of the product is high.
2006/10/2/ · Fish waste (viscera, backbones, heads and tails) was recovered fish merchants and ground. 50 kg of the ground fish was mixed with 10 kg of molasses and incubated in 200 kg barrels in closed
2021/1/15/ · The problem of poor carbon source is a common technical bottleneck inhibiting the nutrients removal in biological wastewater treatment. This study aimed to investigate the feasibility of using food waste (FW) fermentation liquid (FL) as the external carbon source to enhance biological nitrogen and phosphorus removal (BNPR) in
2020/8/1/ · The analysis of PCR-DGGE and Illumina Miseq revealed that the wheat leaf surface and near-root substrate had different microbial communities at different periods of wheat ecosystem development and showed that the relative highest diversity of microbial communities appeared at late and middle periods of the plant ecosystem, respectively.
2015/11/1/ · This article discusses many of the problems that can arise related to large-scale industrial fermentation vessels (that is, those with a capacity up to 1 million gal) that are increasingly being used for industrial bioprocesses. It also presents recommendations for appropriate CIP and sterilization design for large-scale systems.
2019/1/1/ · 1. Introduction. Activated sludge process has been extensively used in municipal sewage treatment [1].Although it is effective to clean wastewaters, large quantity of waste activated sludge (WAS) is generated as by-product daily [2], [3], [4], [5].Generally, a wastewater treatment plant (Q = 10 5 m 3 /d) would produce ∼50 tons WAS daily. It was
Why. When fermented food waste is consumed by soil-living organisms they release and transform its nutrients into the form that plants need. Just as important, they live, multiply, eat one another and die, and their excretions and dead bodies add to “soil organic matter”. Their activities also improve soil texture for plant roots to grow.
2015/1/1/ · The top layer (80% butanol and 20% water) is returned to the butanol column, and the bottom layer (4% butanol and 96% water) is returned to the beer column. Approximately 35,000 lb stream is consumed for every ton of solvents produced. Fig. 24.22. Process flow sheet of butanol-acetone-ethanol fermentation.
2011/5/1/ · A Box–Bhenken design with four variables (shrimp shell concentration (SSC), glucose concentration, incubation time and inoculum size) and three levels was used for the determination of the deproteinization and demineralization efficiencies in fermented shrimp shells by Pseudomonas aeruginosa A2. The fermentation variables were
2021/2/15/ · Food waste fermentation and separation. To explore the effect of gauze separation on the production and compositions of fermentation products, two sequencing batch reactors (SBRs) with each working capacity of 1 L were used in this study. Two fermentation reactors were operated at constant temperature (35 ± 2 °C) without pH
2024/5/28/ · When dark fermentation is carried out alone, the liquid fermentation waste will be discharged from the liquid outlet after fermentation in the tank.
