Formation
of acetate during incomplete oxidation of lactate by Desulfovibrio sp.
strain SHV was checked by gas chromatography (gas chromatograph
model 3400; Varian Instruments, Sunnyvale, CA, USA) on Chromosorb
SP1220 (WAW 80-100 mesh; column length, 3.0 m; 120°–160°C;
carrier gas, N2 at 45 ml/min; flame ionization detector [220°C]).
Peaks of interest on liquid chromatograms were analyzed by
