A total of 15 marine Bacillus species were isolated from estuarine sediment of Punnaikayal estuary of Tuticorin, Tamilnadu, India. The marine Bacillus was evaluated for biocontrol activities against Aspergillus niger a phytopathogenic fungus causing Aspergillus rot of papaya, collar rot of groundnut, post harvest disease, food spoilage and human pathogen. In vitro dual culture and volatile assay of marine Bacillus and A. niger on agar plates showed that the bacterium effectively inhibited radial growth of the fungus. Among the inhibitory marine Bacillus isolates, MB-13 and MB-6 significantly suppressed hyphal growth of A. niger in dual culture assay and MB-6, MB-13, MB-5 isolates inhibit the growth of A. niger by volatile assay. These findings support the potential use of marine Bacillus also for biological control of plant pathogens.
