A mutant strain of Klebsiella pneumoniae, termed GEM167, was obtained by γ irradiation, in
which glycerol metabolism was dramatically affected on exposure to γ rays. Levels of
metabolites of the glycerol reductive pathway, 1, 3-propanediol (1, 3-PD) and 3-
hydroxypropionic acid (3-HP), were decreased in the GEM167 strain compared to a control
strain, whereas the levels of metabolites derived from the oxidative pathway, 2, 3-butanediol
(2, 3-BD), ethanol, lactate, and succinate, were increased. Notably, ethanol production from …
