Evalution of enzyme effects of Bacillus cereus to degreed mycelium of Ganomderma

Abstract

This study aimed to evaluate the efficiency of endogenous bacteria in inhibiting the growth of Ganoderma fungus the major causal pathogen of Basal Stem Rot (BSR) disease in palm. This endophytic bacteria were isolated from symptomless oil palm roots it is showed inhibitory effect by suppressing the mycelial growth of G. boninense. The isolated bacteria were screened in vitro by culture filtrate test for its antagonistic properties towards G. boninense. the bacterial endophytes was established to have potential as biocontrol agents based on their percentage inhibition of radial growth (PIRG) more than 70%. Shrinkage of hyphae in bacillus was more apparent in through mycelial growth test. Therefore, in vitro activities of bacillus against G. boninense in these studies suggested that these endophytic endophytic bacteria can be used as an effective biological control agent.
