Enhanced thermophilic bioenergy production from food waste by a two-stage fermentation process

Enhanced rhamnolipids production by Pseudomonas aeruginosa based on a pH stage-controlled fed-batch fermentation process.

Rhamnolipids find broad applications as natural surfactants, emulsifiers, and antibiotics because of their low toxicity, high biodegradability and environmental soundness. In this study, a pH stage-controlled process of fermentation of rhamnolipids by Pseudomonas aeruginosa O-2-2 was established. A yield of 24.06 g/L in batch fermentation was achieved in a 5-L fermentor via the optimization of ...

Enhancement of bioenergy production from organic wastes 1 by two - stage anaerobic hydrogen and methane production

Glucoamylase production from food waste by solid state fermentation and its evaluation in the hydrolysis of domestic food waste

Enhanced acarbose production by Streptomyces M37 using a two-stage fermentation strategy

In this work, we investigated the effect of pH on Streptomyces M37 growth and its acarbose biosynthesis ability. We observed that low pH was beneficial for cell growth, whereas high pH favored acarbose synthesis. Moreover, addition of glucose and maltose to the fermentation medium after 72 h of cultivation promoted acarbose production. Based on these results, a two-stage fermentation strategy w...

Increasing CoQ10 production by Rhodopseudomonas palustris J001 using a two-stage fermentation process.

CoQ10 is used not only as a medicine but also as a food supplement due to its various physiological activities. The production of CoQ10 by microbes is a successful approach for generating large amounts of this natural product. The effects of dissolved oxygen (DO) contents and the two-stage fermentation process on cell growth and CoQ10 production by Rhodopseudomonas palustris J001 were investiga...
