Titer fermentation

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.
