Abstract
A new fermentation strategy, one-step fermentation was developed for PHB production with high cell concentration and good productivity in a simplified way. Combined with the research results of PHB synthesis with the method of shake-flasks fermentation cultivation, the fermentation system was built based on the characteristics of fermentation tank cultivation,which was much superior to the traditional two-step fermentation. Based on shake flask studies, the full advantages of fermentation culture was taken to achieve the improvement of PHB production. Through this fermentation method with high PHB accumulation capacity, it provides a feasible way to expand the scale of PHB production, and promotes PHB industrial production process using Methane-Utilizing mixed Culture.
