Abstract:
Sponge Dysidea avara-associated bacteria were isolated by dilution-plate method and the bacterial anti-microbial activities were screened for Escherichia coli,Staphylococcus aureu, Pseudomonas fluorescens, Bacillus subtilis,Aspergillus niger, Candida albicans,Pacecilomyces variotii by agar diffusion method.At the same time, morphology observations, biochemical and physiological identification of active strains were made. In this paper, 149 strains were isolated from sponge Dysidea avara.20 strains, which amount to 13.4% of the total isolated strains, were found to have anti-microbial activity against fungi and gram-positive bacteria and were identified to be the genus Bacillus sp.
