WebDec 1, 2024 · Electro-fermentation (EF), including unbalanced fermentation and microbial electrosynthesis, has been proposed as a novel fermentation process, which could use electron transfer to promote substance metabolism via changing the intracellular redox state, such as the oxidation reduction potential (ORP) and the NADH/NAD+ ratio [ 7 ]. WebJan 25, 2024 · The flask fermentation results showed that ectoine titers of ET09 (ectA:ectB:ectC = 2:1:1) and ET10 (ectA:ectB:ectC = 3:1:1) were 6.85 g/L and 2.39 g/L lower than that of ET08 (ectA:ectB:ectC = 1:1:1), respectively . This indicated that the synthesis of ectoine was not effectively enhanced with an increase of the copy number of ectA.

WebAn 8-stage C-HCDC lactic acid fermentation resulted in 212.9 g/L of titer and 10.6 g/L/h of productivity, corresponding to 101 and 429% of the comparable lactic acid fed-batch, respectively. The penicillin production model predicted 149% (0.085 g/L/h) of productivity in 8-stage C-HCDC with 40 g/L of cell density and 289% of productivity (0.165 ... www.ncbi.nlm.nih.gov thrall server status
Fermentation Titer Optimization and Impact on Energy and Water ...
WebVarious fermentation parameters, nutrient additions, and operation variables were applied and finally 33.8 g/L of l-lysine was obtained. This l-lysine titer is still below that of starch based fermentation, but already 3-5 folds greater than that of other alternative feedstocks based fermentation. WebIn industrial fermentation, molasses, biomass hydrolysate, and crude glycerol are preferred substrates. After fed-back fermentation condition optimization, the highest titer of organic acids exceeded 200 g/L, which is competitive with the chemical synthetic approaches (Xu et al., 2024). Table 1. WebMay 17, 2016 · Concurrently, the DOT was controlled above 20 %. Using glucose fed-batch fermentation, DOT control, and a pH shift strategy, the 5-KGA titer was increased to 162 ± 2.12 g/L with the 2.53 g/(L · h) productivity by the recombinant G. oxydans ZJU7 strain, which was increased by 10-fold compared to the wild-type strain (Fig. 5c). This indicated ... underwriter and processor
