Analysis on inducement of antibiotic production in marine bacteria


Competition amongst microbes for space and nutrients in the marine environment is a powerful selective force which has led to the evolution of a variety of effective strategies for colonizing and growing on surfaces. As the primary role of antimicrobial activity can be to antagonize competitors, bacteria may also produce antimicrobial compounds when they sense the presence of competing organisms. Bacterium - bacterium antagonistic interactions involving antibiotics are well documented in soils but work relating to this in marine environment is scanty. In this present study marine bacterial strains were induced for enhancement as well as for antibiotic production. In the present study out of the 75 antibiotic non-producer strains used for inducement study, 20 strains were induced. Inducements of antibiotic production by the bacterial strains were carried with heat killed and live Escherichia coli and Pseudomonas aeroginosa cells.
