摘要

Microbial diversity based on plant-microbe interaction as well as most fungal diseases which are such multipathogen complexes have been long researched. Most beneficial microbes promote the growth of the plant but inhibit the growth of plant pathogen as biocontrol agents and are reported for their establishment being microbial communities associated to the plant roots. We were interested in understanding the antagonistic activity of root-associated bacterial communities in the rhizospheres. In this experiment, common bacteria associated with banana root exudation that were cultivated and isolated harbored specific antagonistic to common pathogen. In the experiments, the interior of the pseudostem (endosphere) root samples had bacterial more CFU counts than the rhizosphere of banana roots (6-8 and 4-5 CFU/ g, respectively). Antibacterial activity as bioactive agents were determined from these microbes as antagonistic activity against plant pathogens. The isolate species were Bacillus indicus, Pseudomonas palleroniana, Penicillium spp and Fusarium oxysporum. From this study, the isolates of indigenous bacteria obtained from banana rhizosphere can be potential for being disease-suppressive microorganisms promising perspectives for sustainable plant protection.
