ABSTRACT
A total of 17 endophytic heterotrophic bacteria were isolated from the leaves of five different halophytes from Karangkadu mangrove ecosystem along Palk Strait, Tamil Nadu, India. The percentage occurrence of Gram negative strains is higher than Gram positive strains. Eight strains were showed broad spectrum of activityagainst tested antibiotic resistant pathogens (n=3), urinary tract infectious pathogens (n=3) and eye pathogens (n=7). Among them, THB12 exhibited higher inhibitory activity (14±1.31 mm) against Pseudomonas sp. of urinary tract infectious pathogen. It’s concluded from present the study that, the endophytic bacteria isolated from the mangrove halophytes of Karangkadu mangrove ecosystem showing potential broad spectrum antibacterial activity.
