Bacterial chitinase in the stomachs of marine fishes from Yaquina Bay, Oregon, USA

  • T. D. Goodrich

The occurrence of chitinase in the stomach contents of Enophrys bison and Platichthys stellatus was investigated. The highest chitinase activity and the greatest percentage of chitinoclastic bacteria in relation to the total bacterial flora were associated with fish whose stomach content was composed primarily of chitinous animals. Stomach contents lacking visible chitin possessed low or no detectable levels of chitinase activity and few chitinoclastic bacteria. Juvenile E. bison treated with chloramphenicol to remove their indigenous bacterial flora had no detectable level of chitinase in their stomach contents while non-treated juveniles showed inducible chitinase activity, indicating the bacterial origin for the chitinase.
