Research Interests:

I’ve been conducting research in the field of anaerobic microbiology for about 20 years. During these years I’ve studied the physiology, activity and interactions in natural environments of all major groups of strictly anaerobic bacteria: methanogens, acetogens and sulfate-reducers. I was involved in microbial studies of various oil fields and related infrastructure, anaerobic marine environments and contaminated groundwater aquifers. I place a special emphasis on isolation and description of novel microorganisms/microbial consortia capable of degradation of hydrocarbon compounds. Currently my major interest is biodegradation of different classes of hydrocarbons under sulfate-reducing and methanogenic conditions. This involves studies of novel metabolic pathways and biochemical reactions, such as the fumarate addition reaction, used by anaerobic bacteria for activation of hydrocarbon substrates in the absence of oxygen.
