Abstract

The objective of this study is to isolate endophytic bacteria from Azadirachta indica (neem). We isolated 7 strains of endogenous bacteria from the neem tree. By investing the anti-fungal and antibacterial activities of endophytic bacteria in A. indica by well diffusion agar method, we noticed there was KT2 strain which resisted to Salmonella typhi and Staphylococcus aureus (10.67 ± 0.33 mm and 9.67 ± 0.33 mm), KT3 strain showed the inhibitory activity to three human pathogenic fungal (Candida albicans, Trichophyton mentagrophytes, Trichophyton rubrum), two strains (KT1, KT2) which resisted to C. albicans and T. rubrum. According to Cowan and Steel's manual, the result of biochemical identification showed that the KT2 strain was the Bacillus subtilis species.
