Abstract
Selected endophytic bacteria characteristic and growth studies using bioreactor were conducted to establish the most effective endophytic bacterial consortium to produce powder plant growth hormone as a biofertilizer for cocoa plants. Four selected endophytic bacterial isolates with potential to be developed as biofertilizer, that has been isolated within the tissues of healthy Theobroma cacao L. plants were identified as Bacillus amyloliquefaciens, B. pumilus, B. subtilis, and Pantoea agglomerans based on previous 16S ribosomal DNA sequences. The strains already tested for their mutual compatibility are to be developed as mixtures of endophytic bacterial consortia biofertilizer. In conclusion, results obtained from this study has reveal that the selected endophytic bacteria possess the greatest growth activity at the end of exponential phase at 24 hours of cultivation period in a culture medium individually using a bioreactor.
