Dr. Shobha K. Jayanna

Assistant Professor

Dr. Shobha K. Jayanna is presently working as an Assistant Professor in the SBAS, Dayananda Sagar Institutions, Bangalore. She has been actively involved in research on various aspects of Environmental Microbiology. Her research interests are projected in the various fields of bioremediation of contaminated soils, water quality assessment of drinking water, and biohazards of pesticides. She has published five papers to her credit in national and International journals. Her research involves the isolation and characterization of bacterial consortium of Bacillus sp and Pseudomonas sp capable of degradation of Methoxychlor, 2, 4- dichlorobiphenyl. The report indicated the results of bioanalytical studies using GC-MS which revealed the degradation of Methoxychlor to carboxylic acids and 2,4-dichlorobiphenyl to catechol. The results were significant with respect to the degradation activity under in-situ conditions, rendering the organisms to be potent in natural environments for degradation of recalcitrant compounds.
