Rhizopus and ChlamydomucorStrains Surveyed for Milk-Clotting, Amylolytic, and Antibiotic Activities

Abstract
SUMMARY Nine strains of Chlamydomucor oryzae and 347 strains of Rhizopus, representing 10 species, were grown in rice flour and wheat flour media. When grown on wheat flour medium, nearly all strains exhibited amylolytic activity and more than 300 strains showed milk-clotting activity. Almost all strains of R. arrhizus exhibited antibiotic activity against NRRL B-765 Bacillus subtilis. The 23 strains of R. stolonifer showed none of these activities.
