Leuconostoc mesenteroides growth kinetics with application to bacterial profile modification
(Wiley Subscription Services, Inc., A Wiley Company, 1994-04-15)
Bacterial profile modification (BPM) is being developed as an oil recovery technique that uses bacteria to selectively plug oil depleted zones within a reservoir to divert displacing fluids (typically water) into oil-rich ...
Phosphate feeding to permit growth while maintaining secondary product synthesis
(Springer-Verlag, 1988-02)
Maintaining high metabolic activities for extended periods by feeding small amounts of the growth limiting nutrient was examined for the production of cycloheximide by Streptomyces griseus . Batch studies indicated that ...
Biomass plug development and propagation in porous media
(John Wiley & Sons, Inc., 2001-02-05)
Exopolymer-producing bacteria can be used to modify soil profiles for enhanced oil recovery or bioremediation. Understanding the mechanisms associated with biomass plug development and propagation is needed for successful ...
Hydrogen peroxide production using chemically treated Pichia pastoris cells
(Elsevier, 1994-01)
A new method has been developed to prepare intact cell systems to produce hydrogen peroxide (H2O2) using methylotrophic yeast Pichia pastoris. The high alcohol oxidase (EC 1.1.3.13; AOXase) content in the living P. pastoris ...
Reduction of porous media permeability from in situ Leuconostoc mesenteroides growth and dextran production
(Wiley Subscription Services, Inc., A Wiley Company, 1996-04-05)
In situ growth of bacteria in a porous medium can alter the permeability of that media. This article reveals that the rate of permeability alteration can be controlled by the inoculation strategy, nutrient concentrations, ...
Effects of extractive fermentation on butyric acid production by Clostridium acetobutylicum
(Springer-Verlag, 1990-01)
The addition of an oleyl alcohol extractant to a batch fermentation of glucose by Clostridium acetobutylicum resulted in a concentration profile that was distinctly different from the non-extractive control fermentation. ...
Mass transfer effects on microbial uptake of naphthalene from complex NAPLs
(Wiley Subscription Services, Inc., A Wiley Company, 1998-12-20)
The bioavailability of naphthalene present as a component of a complex nonaqueous phase liquid (NAPL) comprised by nine aromatic compounds was investigated. Specifically, the effects of naphthalene mass transfer from the ...
