Plant-associated bacteria that live inside plant tissues without causing any harm to plants are defined as endophytic bacteria. Endophytic bacteria were isolated from the surface sterilized pneumatophores of Avicennia marina. Three isolates were selected based on their colonization and occurrence. The isolates SjAM16101 Gram positive rods, SjAM16102 Gram negative rods and SjAM16103 Gram negative rods were identified using 16S rRNA sequencing and identified as Bacillus sp., Enterobacter sp. and Sporosarcina aquimarina, respectively. The nucleotide sequence has been deposited under accession number GU930357 (Bacillus sp.), GU930358 (Enterobacter sp.) and GU930359 (S. aquimarina). Bacillus sp., fixed nitrogen, S. aquimarina produced siderophore and all the three strains solubilized phosphate molecule.
