The Infrared Spectra of Some Acetic Acid Bacteria

Abstract

SUMMARY: The infrared spectra of 22 strains of the genus Acetobacter were significantly different from those of 9 strains of the genus Acetomonas, with one exception. Within each genus, however, the spectra formed smooth graduated series which showed no sudden differences which could be correlated with species boundaries, and exhibited no features which could be traced to the presence or absence of particular biochemical properties. These results support the division of the acetic acid bacteria into two genera Acetobacter and Acetomonas and render unlikely the existence of distinct species within the genera.
