SUMMARY: A survey of the proteolytic bacteria present in the rumens of sheep on different kinds of diets has been made, with special emphasis on the isolation of anaerobic types. The results suggest that proteolytic activity is not confined to a single kind of rumen bacterium, but that it is a variable property possessed by strains of many kinds of bacteria which can be active in the breakdown of other feedstuff constituents. The properties of the bacteria isolated are given.
