Optimization of fermentation conditions for the production of bacterial cellulose by a newly isolated Acetobacter sp. A9 in shaking cultures.

abstract：:Acetone-butanol-ethanol (ABE) fermentation was performed with sugarcane bagasse (SCB) hydrolysate using Clostridium beijerinckii strains. A cost-effective SCB medium was developed with no enzymatic hydrolysis and no supplementation of extra carbon source or expensive nitrogen source. One of the C. beijerinckii strains...
