A novel white rot fungus strain Hohenbuehelia sp. ZW-16 was identified and first used for bioethanol production in this study. It was found that the strain could produce bioethanol with glucose, xylose and arabinose under limited oxygen condition. Then, corn straw hydrolysate and corncob hydrolysate (mainly composed of glucose, xylose, and arabinose) were used for bioethanol production; the former substrate could produce more bioethanol in the experiment. The optimal sugar concentration and nitrogen sources were selected (50 g/L corn straw hydrolysate and 10 g/L soybean meals, respectively) and the maximum yield of bioethanol reached 4.6 g/L after 8 days of fermentation.
