Abstract:

The chitinase-producing abilities of strains isolated from both farming water and digestion guts of Haliotis diversicolor supertexta were studied by a special TCBS(Thiosufate-Citrate-Bile Salts-Sucrose)and by screening the culture media.The resuhs indicate that there are chitinase-producing strains in farming water and digestion gu ts of the abalone.12 bacteria were isolated from abalone digestion gu ts.which account for 34.3%of the total bacterial populations in the guts.Species identification shows that these chitinase-producing strains belong to Vibrio fluvialis and Vibrio minicus.From the ab alone farming water,4 chitinase-producing strains were isolated,which account for 1 1.8% of the total bacterial populations.These 4 strains belong to Vibrio fluvialis.Compared with the farming wa-ter,it is clear that there are more chitinase-producing strains in abalone digestion gu ts,and abalone digestion gu ts display selectivity toward the chitinase-producing strains.
