Fig. 5From: Rich biotin content in lignocellulose biomass plays the key role in determining cellulosic glutamic acid accumulation by Corynebacterium glutamicumBiotin contents in different lignocellulose biomass and biotin content changes during biorefining steps. a Biotin contents in different lignocellulose biomass. b Biotin content changes during biorefining chain. The measured biotin concentration in the hydrolysate and fermentation broth was transformed to the amount of biotin content per kg of the pretreated corn stover. Mean values were presented with error bars representing at least two standard deviationsBack to article page
