Abstract
A selective medium was developed for the primary isolation of opportunistic flavobacteria from potable water. A minimal‐salts maltose yeast extract agar medium (MSMY) supplemented with either kanamycin (MSMY‐K) or tobramycin (MSMY‐T) was effective in suppressing the background microflora from most sources while allowing for the growth of Flavobacterium meningosepticum and Flavobacterium IIb. Opportunistic flavobacteria were isolated from 30% of potable well and 10% of potable distribution water samples tested using MSMY‐K in a membrane filtration technique.
