An Improved Medium for the Enumeration of Chromobacterium in Soil and Water

Authors:

Abstract
Bennett's agar, containing (μg/ml): neomycin, 50; cycloheximide, 50; and nystatin, 50; gave higher counts of Chromobacterium from soil and water samples than did the selective medium of Ryall & Moss (1975). Colonies on the modified Bennett's agar were usually large, deep purple and easily recognized. The strains isolated were identified as Chromobacterium lividum .
