Effect of Acetate upon the Formation of Acetoin in <i>Klebsiella</i> and <i>Enterobacter</i> and its Possible Practical Application in a Rapid Voges-Proskauer Test

Abstract

Acetate stimulates the formation of acetoin during 1-h incubation of Voges-Proskauer-positive strains of Klebsiella and Enterobacter. Of these organisms, 124 of 126 strains were recognized as positive in the presence of acetate, and 106 were recognized as positive in its absence.
