Abstract: To develop biocontrol technology with bacterium against pathogens for prevention from aquatic diseases, we screened a bacillus strain FA08 from mud in an aquaculture area in Ningde, Fujian, China. The strain could produce with cellulase and showed antimicrobial activity, and has been identified as Bacillus licheniformis(Gen Bank Accession number KM892857), based on its 16 S r DNA sequence homology, together with the morphological, physiological and biochemical characteristics. Analysis of its enzyme characteristic showed that the cellulase could stand in a wide p H range from 3 to 10 and remain thermally stable in 30—80°C with relative cellulase activity up to 70%. Moreover, the cellulase was insensitive to UV. In addition, we tested the antimicrobial activity of FA08 against selected aquatic pathogens. The results revealed that supernatant of the strain could inhibit strongly against Aeromonas hydrophila, Vibrio harveyi, Vibrio alginolyticus, Vibrio parahaemolyticus, and Staphylococcus aureus. Therefore, strain FA08 and its cellulase product shall have promising values of development and application for aquaculture.
