2002/5/25/ · Through this practice of back-slopping, the initial phase of the fermentation process is shortened and the risk of fermentation failure reduced.
3 天之前 · The production of short-chain fatty acids (SCFAs) is constrained by substrate availability and the increased fractional pressure of H 2 emitted by acidogenic/fermentative bacteria during anaerobic fermentation of waste activated sludge (WAS). This study introduced a novel approach employing zero-valent iron (ZVI)-activated sulfite
2021/3/1/ · It was found that the total fermentation lasting time and each single cycle fermentation duration were both extended in the coupled system, resulting in much elevating hydrogen production (P H/Broth) and butanol (P B/Broth) production, as well as their yields (P H/Cell or P B/Cell) versus cell. It was attributed to that the pervaporation
2021/10/30/ · The machine has the characteristics of short fermentation cycle, daily processing, large annual production capacity, and no need to configure a high-pressure forced oxygen supply system.
2021/4/27/ · Animal-free dairy utilizes a precision fermentation process that allows the production of a single food ingredient, such as proteins and vitamins, to fully mirror dairy or other animal-derived
Background. The global interest in cellulosic ethanol has surged due to the abundance of feedstock [], increasing concerns for environmental sustainability and security of energy supplies [], and the reduction of greenhouse gas emissions compared to first-generation ethanol [].Production of cellulosic ethanol requires a pretreatment to open the complex

Bacillus subtilis is a Gram-positive bacterium that has gained an unprecedented reputation as an expression system at the industrial scale due to characteristics, such as GRAS (Generally recognized as safe), ease of genetic manipulation, high growth rate on the cheap substrate, and short fermentation cycle. This expression system has been
2024/1/6/ · As the by-product in the biological sewage treatment, waste-activated sludge (WAS) always suffers from the difficulty of disposal. Anaerobic fermentation to achieve valuable carbon sources is a feasible way for resource utilization of WAS, whereas the process is always restricted by its biochemical efficiency. Hence, the WAS was used

2024/1/9/ · The distinct advantages of Bacillus spp. used as microbial cell factories include a short fermentation cycle (around 48 h), ease of cultivation, and robust growth; non-pathogenic Generally Regarded as Safe (GRAS) status; the ability to secrete recombinant proteins in the medium; and the lack of external and endotoxins [1,6].
2017/4/27/ · Fermentation occurs in certain types of bacteria and fungi that require an oxygen-free environment to live (known as obligate anaerobes), in facultative anaerobes such as yeast, and also in muscle cells when oxygen is in short supply (as in strenuous exercise). The processes of fermentation are valuable to the food and beverage
