Efficient 2,3-Butanediol Production from Cassava Powder by a Crop-Biomass-Utilizer, Enterobacter cloacae subsp. dissolvens SDM

Abstract: Background2,3-Butanediol (BD) is considered as one of the key platform chemicals used in a variety of industrial applications. It is crucial to find an efficient sugar-utilizing strain and feasible carbon source for the economical production of BD.Methodology/Principal FindingsEfficient BD production by a newly isolated Enterobacter cloacae subsp. dissolvens SDM was studied using crop-biomass cassava powder as substrate. The culture conditions and fermentation medium for BD production were optimized. Under the… Show more

“…As substrate materials constitute a large part of the cost for microbial 2,3-BD production, a variety of biomasses, such as molasses, corncob acid hydrolysate, waste starch hydrolysate, glycerol, cassava powder, and corncob molasses, have been tested and show promise to reduce the cost of fermentation (1,8,27). Although lignocelluloses are inedible and represent one of the most abundant and inexpensive biomass sources in the world, their utilization is more difficult than storage polysaccharides, such as starch and inulin (1).…”

“…The incubated seed culture was then inoculated (6 % v/v) into the fermentation medium. Simultaneous saccharification and fermentation (SSF) and fed-batch SSF were performed as described in a previous study [32]. For SSF, the liquefied solution of cassava powder was added to maintain an appropriate glucose concentration, and the SSF was carried out at 30 °C and pH 7.0 (addition of 4 M H 3 PO 4 or 6 M KOH).…”
