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 ...
Topical Drug Delivery from Thin Applications: Theoretical Predictions and Experimental Results
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1990-10)
Stainless-steel templates of various thicknesses (75, 200, 800, and 1600 µm) were used to apply propylene glycol/water gels containing methyl or propyl p -aminobenzoates to silicone rubber membranes, and drug delivery was ...
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 ...
Monte Carlo simulations of receptor dynamics: Insights into cell signaling
(Kluwer Academic Publishers; Springer Science+Business Media, 2004-09)
Many receptor-level processes involve the diffusion and reaction of receptors with other membrane-localized molecules. Monte Carlo simulation is a powerful technique that allows us to track the motions and discrete reactions ...
Nanoparticles, molecular biosensors, and multispectral confocal microscopy
(Kluwer Academic Publishers; Springer Science+Business Media, 2004-08)
Complex, multilayered nanoparticles hold great promise for more sophisticated drug/gene delivery systems to single cells. Outermost layers can include cell targeting and cell-entry facilitating molecules. The next layer ...
