Abstract

Bio-imunizer contains an active compound of  Chryseobacterium sp. and Bacillus sp. has been developed by PPTK Gambung. This formula has positive effect on the growth of tea plants also potentially increasing resistance of the plant. The purpose of this study was to determine the effects of bacteria in Bio-imunizer to the rhizosphere bacterial communities as well as the consistency of its existence after application on tea plants at the nursery stage. The technique used in this research is Terminal Restriction Fragment Length Polymorphism based on metagenomic and culture dependent approaches. The value of relative abundance, Shannon diversity index, Pielous evenness index, and Simpson dominance index were calculated. Based on the T-RF profiles of rhizosphere bacterial communities show that Chryseobacterium sp. and Bacillus sp. which is the active compound of  Bio-imunizer consistently found in the tea plant rhizosphere. Application of Bio-imunizer can increase the diversity of rhizosphere bacterial community without affecting the communities that already exist.
