摘要
Improvement in H-2 production was achieved through redirection of metabolic pathways by blocking formation of alcohol and some organic acids in Enterobacter cloacae IIT-BT 08. The wild type strain was more susceptible to allyl alcohol (7 mM) and to the combined effect of NaBr and NaBrO3 (40 mM each at pH 5.5) than were double mutants, with defects in both alcohol and organic acid formation pathways, which had higher H-2 yields (3.4 mol mol(-1) glucose) than the wild type strain (2.1 mol mol(-1) glucose).
