Abstract

SUMMARY: When 108 samples of individual farm milk supplies were held at 3—5° for 72 hr, 35·2% showed increases in coli‐aerogenes organisms of over one‐hundredfold and 10·2% increases of more than one‐thousandfold. The coli‐aerogenes microflora after refrigeration was dominated by Klebsiella cloacae and K. aerogenes I. While some strains of all the coli‐aerogenes types isolated showed growth, though sometimes scanty, on yeast‐dextrose agar in 5 days at 3—5°, the majority of the strains of K. cloacae showed luxuriant growth under these conditions and can be considered as typical facultative psychrophiles of milk.
