| Research Abstract |
To gain basic knowledge for industrial application of crude-oil-degrading methanogenic microorganisms endogenous to petroleum reservoir, we collected reservoir brine samples from petroleum reservoirs and analyzed population structure and methanogenic activity of microorganisms in the reservoirs. Our results suggested an important role of acetoclastic methanogens in the microbial system within a biodegraded oil reservoir. Moreover, we showed that supplementation of complex nutrients could enhance the methanogenic activity of microorganisms endogenous to a depleted oil reservoir.
