Pore-scale investigation of biomass plug development and propagation in porous media
(John Wiley & Sons, Inc., 2002-03-05)
Biomass plugging of porous media finds application in enhanced oil recovery and bioremediation. An understanding of biomass plugging of porous media was sought by using a porous glass micromodel through which biomass and ...
Growth of Leuconostoc mesenteroides NRRL-B523 in an alkaline medium: Suboptimal pH growth inhibition of a lactic acid bacterium
(Wiley Subscription Services, Inc., A Wiley Company, 2005-01-05)
Bacterial profile modification (BPM), a form of tertiary oil recovery, diverts water from the water-flooded high-permeability zone into the oil-bearing low-permeability zone. During field use, exopolymer-producing bacteria ...
Chemical permeabilization and in situ removal of daidzein from biologically viable soybean (Glycine max) seeds
(Kluwer Academic Publishers; Chapman and Hall ; Springer Science+Business Media, 1998-09)
After 24 h of chemical permeabilization with 20% (v/v) methanol at 25 °C, the amount of daidzein released from soybean seeds is 15 to 20% of the amount (0.0423 ± 0.0045 mg/g seed dry wt) obtained by physical grinding. With ...
Fe---P---0 catalysts for methane utilization--catalyst development and identification
(Elsevier, 1990-05)
Fe---P---0 catalyst formulations show great promise for oxidative coupling of methane. They attain yields of C2 hydrocarbons comparable to the best in the literature at a temperature which is far below those reported. The ...
Modeling ssDNA electrophoretic migration with band broadening in an entangled or cross-linked network
(WILEY-VCH Verlag, 2007-08)
We use a coarse-grained model proposed by Graham and Larson based on the temporary network model by Schieber et al.. [1] to simulate the electrophoretic motion of ssDNA and corresponding band broadening due to dispersion. ...
Molecular analysis of the myosin gene family in Arabidopsis thaliana
(Kluwer Academic Publishers; Springer Science+Business Media, 1994-11)
Myosin is believed to act as the molecular motor for many actin-based motility processes in eukaryotes. It is becoming apparent that a single species may possess multiple myosin isoforms, and at least seven distinct classes ...
Biomass evolution in porous media and its effects on permeability under starvation conditions
(John Wiley & Sons, Inc., 2000-07-05)
The purpose of this study was to understand bacteria profile modification and its applications in subsurface biological operations such as biobarrier formation, in situ bioremediation, and microbial-enhanced oil recovery. ...
The effect of feedback regulation and in situ product removal on the conversion of sugar to cycloheximide by Streptomyces griseus
(Springer-Verlag, 1989-03)
An addition of cycloheximide to cycloheximide-producing Streptomyces griseus cultures resulted in reductions in the production rate and in the conversion of sugar into cycloheximide. In situ cycloheximide adsorption was ...
Closed circular DNAs with tandem repeats of a sequence from polyoma virus
(Elsevier, 1974-09)
The R1 restriction endonuclease from bacteria containing the RTF-1 plasmid cleaves polyoma virus DNA at a single site. Virus stocks which have been passaged through cells several times at moderate or high multiplicities ...
Protein extraction using the sodium bis(2-ethylhexyl) phosphate (NaDEHP) reverse micellar system
(Wiley Subscription Services, Inc., A Wiley Company, 1996-04-20)
The reverse micellar system of sodium bis(2-ethylhexyl) phosphate (NaDEHP)/isooctane/brine was used for liquid-liquid extraction of proteins. We investigated the solubilization of cytochrome-c and Α-chymotrypsin into the ...
