Survey of the Sensitivity of Microorganisms to Aflatoxin

Northern Regional Research Laboratory, Northern Utilization Research and Development Division, U.S. Department of Agriculture, Peoria, Illinois

ABSTRACT

Among the 329 microorganisms tested for aflatoxin sensitivity were 30 genera of bacteria, 34 genera of fungi, 4 genera of algae, and 1 protozoan. Twelve species of the genus Bacillus, a clostridium, and a streptomycete were inhibited when 30 µg/ml of crude aflatoxin (36% pure) was incorporated into the growth substrate. A strain of Bacillus brevis and two of B. megaterium were most sensitive to aflatoxin, being inhibited at 10 and 15 µg/ml, respectively.
