A bacterium was isolated from feces of Allomyrina dichotoma larva that feeds on well-rotted sawdust of woods. The isolate was identified as a Gram-positive and spore-forming stain. We named the isolate as Bacillus amyloliquefaciens on the basis of morphological and biochemical properties as well as 16S rRNA gene sequences. The culture of bacteria beneficially increased root and shoot growth of tomato, pepper and cucumber plants compared to the distilled water control. In addition, the bacterial culture strongly inhibited the mycelial growth of several fungal phytopathogens. The drop collapse assay with this culture showed a surfactant activity that is a major indicator for the selection of biocontrol agent. Also, a bacterium has ability of wastewater treatment. These data demonstrate the potential application of B. amyloliquefaciens as a biocontrol agent.
