It is crucial to find an efficient sugar-utilizing strain and feasible carbon source for the economical production of BD.<h4>Methodology/principal findings</h4>Efficient 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 optimal conditions, 78.3 g l(-1) of BD was produced after 24 h in simultaneous saccharification and fermentation (SSF), with a yield of 0.42 g BD g(-1) cassava powder and a specific productivity of 3.3 g l(-1) h(-1). A higher BD concentration (93.9 g l(-1)) was produced after 47 h in fed-batch SSF.<h4>Conclusions/significance</h4>The results suggest that strain SDM is a good candidate for the BD production, and cassava powder could be used as an alternative substrate for the efficient production of BD.Ailong WangYouqiang XuCuiqing MaChao GaoLixiang LiYu WangFei TaoPing XuPublic Library of Science (PLoS)articleMedicineRScienceQENPLoS ONE, Vol 7, Iss 7, p e40442 (2012)
