Abstract
Isolation of new microbial species from extreme environments is one of the most efficient approaches for the development of novel bioactive metabolites. The aim of the present study was to explore the pharmaceutical bacterial resources from the water and sediments of hypersaline Lake Urmia. Using different culture conditions and media led to the isolation of 20 bacterial strains. Halophilic bacteria were screened for the production of antibacterial agent against multi-drug resistant strains of Escherichia coli through agar well diffusion assay. Halophilic bacteria DNA extraction was done by boiling method. The results showed that two Halomonas strains, LUH16 and LUH20 identified by analysis of 16S rRNA gene sequences were the potent producers of antimicrobial metabolites against various strains of E. coli. Furthermore, gas chromatography-mass spectrometry (GC-MS) analysis revealed the presence of eight secondary metabolites with the relevant antimicrobial properties. Our findings led us to focus on Halomonas strains as potent producers of antimicrobial compound that might be an alternative against antibiotic-resistant pathogens such as pathogenic Escherichia coli.
