H. SUGITA, J. KAWASAKI, J. KUMAZAWA AND Y. DEGUCHI. 1996. The amylase‐producing ability of intestinal bacteria in one marine crab and seven fish species was determined. Mean total viable counts ranged from 1.3 × 10 5 to 1.5 × 10 8 cfu g −1 , and Vibrionaceae were predominant in all specimens. Of 1585 strains examined, 341 (21.5%) produced ≥0.01 U amylase ml −1 . Percentage of producers (≥0.01 U ml −1 ) differed among genera/families. High abilities (≥0.05 U ml −1 ) were found in 1.4‐3.6% of Enterobacteriaceae, Pseudomonas and Vibrionaceae strains. On the other hand, percentage of producers varied with animal species. These results reveal that the amylase producers were widely distributed in the digestive tracts of coastal animals including crabs and fish, irrespective of their food habitats.
