Resumo: | This research aimed to investigate the antagonistic activity of the bacterial endophytes from Myanmar medicinal plants. Thirty-one bacterial isolates were isolated from Myanmar medicinal plants: Tinospora cordifolia (Wild.) Miers., Catharanthus roseus G. Don., Tectona hamiltoniana Wall. and Boscia variabilis Collett & Hemsl. (Capparaceae). Dual culture and agar well diffusion methods were used for antimicrobial assay. One endophyte from Catharanthus roseus and two bacterial isolates from Boscia variabilis Collett & Hemsl. (Capparaceae) had not only the antibacterial activity towards the human pathogenic bacteria but also the antifungal activity against the plant pathogenic fungi. From 16S rRNA sequencing, one strain from Catharanthus roseus G. Don. was Bacillus amyloliquefaciens DSM7 and two antagonistic strains from Boscia variabilis Collett & Hemsl. (Capparaceae) were Bacillus subtilissubsp. subtilis str. 168 and Bacillus amyloliquefaciens DSM7, respectively. The best medium for the maximum production of the bioactive compounds was Bacillus medium supplemented with the 4% of starch and 0.3% of peptone for B. amyloliquefaciens DSM7 and B. subtilis subsp. subtilis str. 168 showed the maximum antimicrobial compounds production when it was incubated in the medium amended with 3% of starch and 2% of peptone. The optimum conditions for the the maximum production of the antimicrobial compound were the medium pH of 6 at 35 °C after two days of incubation for B. amyloliquefaciens DSM 7 and B. subtitlis subsp. subtilis str. 168 secreted the maximum concentration of the bioactive compounds at pH 7.5 and 35˚C on second day incubation period. In conclusion, the isolated endophytic bacteria showed the strong antimicrobial activity towards the pathogenic microbes and they could be used in medicine and agriculture as well. |
