文摘

Novel glucose/acetate co-substrate ABE production by co-culturing/glucose limitation. Acetone production enhanced and NADH dependent butanol synthesis suitably restricted. Acetone production of C. acetobutylicum fully utilized by delaying butanol inhibition. Maximum acetone concentration and acetone/butanol ratio at 11.74 g/L and 1.02. Promoting products diversity and bio-acetone production in ABE fermentations.
