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