On the Formation of Acetoin by Acetobacter [PDF]

Journal of General Microbiology, 1959
SUMMARY: The formation of acetoin was studied with 44 strains of the genus Acetobacter, when growing on a medium containing DL-lactate as the main carbon source. Most of the strains produced only limited amounts of acetoin. However, strains of the species A.
