Aerobic and Facultative Anaerobic Spore-forming Bacteria Isolated from Spoiled Canned Foods

Abstract

The isolates from spoiled canned foods were identified by the simplified method. Among 228 strains examined, 199 strains (87%) could be identified as follows; Bacillus coagulans, 56; B. subtilis, 48; B. licheniformis, 36; B. circulans, 22; B. stearothermophilus, 20; B. cereus, 8; B. macerans, 3; B. polymyxa, 2; B. pumilus, 2 and B. brevis 2. The simplified formulae table was proposed for differential identification of commonly encountered species of genus Bacillus in canned food spoilage.
