Endophytes are endosymbiotic groups of microbes colonized in plants. These endophytes are of major interest due to multifaceted plant growth promotion (PGP) activities like production of various metabolites, their defense response towards plant pathogens and also help to combat the stress in plants. South Gujarat region is declared as an export fruit zone for mango, banana and sapota. Hence, present study aims to isolate the endophytes from the pseudostem and suckers of banana grown in South Gujarat region. Total 21 different bacteria were isolated, purified and identified by 16S rRNA. Majority of the genera belongs to Bacillus followed by Klebsiella. All these isolates were evaluated for their various PGP activities like P solubilization, Indole Acetic Acid (IAA) production, organic acid production, biofilm formation and their antagonistic activity against some plant pathogenic fungi. Isolates were examined for their ability to produce various organic acids. They showed promising results in various PGP activities. Organic acid production profile was also monitored using HPLC for various organic acid secrets by isolated organisms. They were also tested for their antagonistic activity against Macrophomina phaseolina, Alternaria spp. and Sclerotinum spp. of plant pathogen and showed promising results in inhibition of these pathogens. Among all the tested isolates isolates BN2 and BN5 belongs to Klebsiella and BN9 & BN15 belongs to Bacillus sp. showed more promising results and can be used as application of biofertilizer for banana plant.
