Abstract : Prolonged usage of chemicals in agriculture has devastated biodiversity to a large extent including microbial diversity and density. Upon intense exposure certain microorganisms acclimatize to chemical influenced soil and exploit those chemicals as their sole source of carbon and/or nitrogen. Bioremediation studies over the past decades predominantly imply on isolation of Pseudomonas species with the property to consume chemical contaminants as their source of energy. Pseudomonas spp. have adapted themselves to extreme conditions by altering their metabolic pathway. Hence these can be to some extent denoted as bio-indicators of chemical contaminants. But suggesting Pseudomonas spp. for field study or for bioremediation threatens us in particular with the development of antibiotic resistance and instigating secondary infections, thus restricting their application. The present study involves in possibility of Pseudomonas species to be considered for bioremediation by testing their ability in causing mortality in zebrafish. Isolates for the comparative study include P. aeruginosa (clinical isolate), P. aeruginosa (soil isolate with pesticide degradation property) and P. pseudoalcaligenes (soil isolate with pesticide’s carrier molecule degradation property). Results obtained confer that antibiotic resistance and mortality caused by the clinical strain was significantly higher thus advocating an affirmative annotation for the field application of soil isolates.
