Diversity, Molecular Characterization and Bioremediation Potential of Cadmium Resistant and Biphenyl Degrading Marine Bacteria

Abstract

This thesis illustrates work on the unculturable marine bacterial diversity along the contaminated coasts of Odisha and Andhra Pradesh of Bay of Bengal, India and characterization of few culturable marine bacteria for enhanced utilization in bioremediation. Presence of cadmium and biphenyl in the range of 0.45±0.07 to 1.87±0.03 ppm and 0.78±0.03 to 16.95±0.45 µg/g respectively in sediments has proposed the isolation of cadmium resistant and biphenyl degrading marine bacteria. From unculturable metagenome sequence analysis, highest bacterial diversity with a total species of 18662 and Shannon diversity index of 10.03 was reported with Proteobacteria as the most abundant phylum...
