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 ...
Molybdenum nitride catalysts : I. Influence of the synthesis factors on structural properties
(Elsevier, 1994-03)
Effects of the synthesis parameters on the structural properties of molybdenum nitride catalysts, prepared by the temperature-programmed reaction of MoO3 with NH3, have been examined. Molybdenum trioxide was heated in ...
Hydrodesulfurization over model sulfide cluster-derived catalysts
(Elsevier, 1991)
There is growing interest in the use of organometallic clusters as precursors to model heterogeneous catalysts. This interest is partially derived from the expectation that "solid-state metal complex catalysts" will be ...
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, ...
Acid- and base-treated Fe 3+ -TiO 2 -pillared clays for selective catalytic reduction of NO by NH 3
(Kluwer Academic Publishers; Springer Science+Business Media, 1999-03)
Fe 3+ -ion-exchanged delaminated pillared clays (PILCs) have been found previously to be more active than the vanadia-based catalysts for selective catalytic reduction (SCR) of NO by NH 3 . The effects of acid treatment ...
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 ...
