The Vibrio sp. forming biofilm on biotic surface especially chitin and algae was investigated using
artificial chitin and Anabaena variabilis from pure culture of laboratory and glued to plexiglass disc. The
presence of culturable Vibrio spp. were investigated using cultural technique for TCBS agar medium after
homogenization and physicochemical parameters were measured by standard techniques. The Pearson
correlation coefficient applied by SPSS software. The results indicated that out of 13 sampling period, only
V. cholerae O1 was isolated 7.7% sample while 30.8% samples were positive for V. cholerae non-O1,
V. proteolyticus and V. mimicus from canal site. From pond ecosystem, all the chitin samples were negative for
V. cholerae O1 but 15.4% were positive for V. cholerae non-O1 and V. proteolyticus and 30.8% samples were
positive for V. mimicus. The biofilm formation is significantly correlated with the pH, DO and CO2
concentration present of the corresponding water. This study indicates that biotic surface like chitin and algae
could function to form biofilm and the water physicochemical parameters have the relationship with the Vibrio
community present in the samples.
Key words: Algae, biofilm, chitin, physicochemical parameters, vibrio, ,
