Across multiple independent replications and varying NaCl concentrations, we found that 1 mol of lactic acid was anaerobically metabolized by L. buchneri in fermented cucumber
media to produce approximately 0.5 mol acetic acid, 0.37 mol 1,2-
propanediol, and 0.13 mol ethanol. These products are consistent
with the pathway proposed by Oude Elferink et al. (2001). However,
the ratio of end products differed somewhat in FC from that
previously reported in microbiological media. We found a slightly
greater proportion of ethanol produced in FC than in the aforementioned
study where itwas reported that 1 mol of lactic acidwas
converted to 0.48 mol acetic acid, 0.48 mol 1,2-propanediol, and
0.04 mol ethanol.
