abstract：:Growth of Prevotella ruminicola strains B(1)4 (subsp. brevis) and D31d (subsp. ruminicola), was inhibited by protamine, a polycationic, low molecular mass protein. Results showed that protamine has a bacteriocidal effect when present in concentrations exceeding 30 micrograms ml-1. Protamine exerted its toxic effects b...
