[Some properties of bacteriocins from Erwinia].

The following properties of eight bacteriocins produced by Erwinia strains were investigated: thermal stability, sensitivity to proteolytc enzymes and enzymes involved in nucleic acid catabolism, dialyzability through a cellophane membrane. Their molecular weight was also measured. The bacteriocins proved to be protein substances with a molecular weight of 17,000--33,000 that differed in their thermal stability and sensitivity to proteolytic enzymes.
