INFRA-RED SPECTROSCOPY OF ZYMOMONAS CELLS

Abstract
The IR spectra of lyophilized cells of 38 Z. mobilis strains were compared. The broad absorption maxima correspond to those found in other organisms. Strain-specific differences were found in Z. mobilis ssp. mobilis. They were most prominent in the absorption region between 1000-1200 cm-1 in the strains VP2, Z2 and 70.7. One spectral feature differentiates Z. mobilis ssp. pomaceae from Z. mobilis ssp. mobilis, i.e., the occurrence of a shoulder at 960 cm-1 in the former instead of a distinct peak in the latter.
