Bioethanol production from mannitol by a newly isolated bacterium, Enterobacter sp. JMP3

► A new Enterobacter sp. JMP3 capable of degrading Laminaria japonica was isolated. ► This bacterium showed high yields of ethanol production from mannitol and glucose. ► Mannitol was proved to be better carbon source for ethanol production than glucose. ► M1PDH pathway of mannitol dehydrogenation was verified in Enterobacter sp. JMP3.
