Oil biodegradation by native bacteria is one of the most important natural processes that can attenuate environmental impacts marine oil spills. Existing models for kinetics are mostly dissolved oil. This work developed a new mathematical model droplets and applied to estimate time scale under conditions relevant Deepwater Horizon spill in Gulf Mexico. In model, composed various sizes following gamma function distribution. Each droplet shrinks during microbe-mediated degradation at oil-water...
To establish a biotechnological system to convert CO2 into methane, we are trying develop new bio-conversion technology based on "electromethanogenesis", bio-electrolysis reaction using microbially-catalyzed electrode. In this study, characterized bio-electrochemical properties of electromethanogenic by Methanothermobacter thermautotrophicus strain AH, thermophilic methanogen. The methanogen can electromethanogenically produce methane without exogenously-supplied hydrogen. the reaction,...
A process-based mechanistic reactive transport model was developed to understand how in-situ coupled processes and operational factors affect selective plugging of carbonate formations by the fermenting bacteria Leuconostoc mesenteroides that produces a polymer dextran. The growth L. associated (bio) geochemical reactions were simulated explicitly with enzyme activity at field scale over spatial extents hundreds meters. Simulations performed explore controls on bioplugging high permeability...
To develop a technological system to add substantial value CCS operations, we are proposing employ new bio-electrochemical reaction, called "electromethanogenesis", convert geologically-stored CO2 into methane, recycled energy source. In this study, showed that microorganisms derived from subsurface reservoir were electromethanogenically active. Moreover, the microbial consortium selectively enriched based on electrochemical activity had highest electromethanogenic reported so far. Thus, our...
