Microbial depolymerization processes of exogenous type are studied by modeling and simulation. A mathematical model is transformed to remove a temporal factor of a degradation rate, and an inverse problem is solved numerically to determine the molecular factor using weight distributions with respect to the molecular weight before and after cultivation of a microbial consortium on plyethylene gl...

BACKGROUND Microbial fuel cells (MFC) and microbial electrolysis cells are electrical devices that treat water using microorganisms and convert soluble organic matter into electricity and hydrogen, respectively. Emerging cellulosic biorefineries are expected to use large amounts of water during production of ethanol. Pretreatment of cellulosic biomass results in production of fermentation inhib...

In the present study, the potential of a bacterial consortium of Enterobacter cloacae and Pseudomonas sp. (ERCPPI-2) for microbial enhanced oil recovery was investigated. Various mechanisms of enhanced oil recovery (EOR) as a result of using ERCPPI-2 and its metabolic products were studied in detail. The obtained results showed that under simulated reservoir ...

The microbial consortia from produced water at two different oil fields in Alaska (Kuparuk) and the North Sea (Ninian) were investigated for sulfate-reducing and methanogenic activity over a range of temperatures and for a variety of substrates. The consortia were sampled on site, and samples were either incubated on site at 60(deg)C with various substrates or frozen for later incubation and an...

Land-filling option is drying out with rapid pile up of organic waste in urban areas; the problem can be circumvented with accelerated anaerobic decomposition which can also be a source of valuable bio-fuel. But many municipal anaerobic waste treatment systems fail due to the lack of adequate microbial inoculum and also hampered by the doubts on many aspects of its operation and stability. In t...
