An investigation of the mobility, viability, and activity of polycyclic aromatic hydrocarbon (PAH) degrading bacteria in an electric field is presented. Bench-scale model aquifers were used to test electrophoresis and electroosmosis as potential mechanisms ...
An extensive random mutagenesis study on the function of nine residues in the subunit binding site of FimC was conducted to evaluate the mol. mechanisms of subunit binding by FimC and the contribution of chaperone surface residues. Five plasmid libraries o ...

We have measured the effect of bacteria adsorption on the resonant frequency of microcantilevers as a function of the adsorption position and vibration mode. The resonant frequencies were measured from the Brownian fluctuations of the cantilever tip. We fo ...
This paper describes the preparation, characterization, and enzymatic activity of complex coacervate core micelles (C3Ms) composed of poly (acrylic acid) (PAA) and poly (N- methyl-2- vinyl pyridinium iodide)-b-poly (ethylene oxide) (PQ2VP-PEO) to which the ...
The presence of a 174 kb plasmid called pMUM001 in Mycobacterium ulcerans, the first example of a mycobacterial plasmid encoding a virulence determinant, was recently reported. Over half of pMUM001 is devoted to six genes, three of which encode giant polyk ...
Methylobacterium dichloromethanicum DM4 is able to grow with dichloromethane as the sole carbon and energy source by using a dichloromethane dehalogenase/glutathione S-transferase (GST) for the conversion of dichloromethane to formaldehyde. Mammalian homol ...
Phosphorylated lipids play important roles in biological systems, not only as structural moieties but also as modulators of cellular function. Phospholipids of pathogenic bacteria are known to play roles both as membrane components and as factors that modu ...
The dynamics of host-pathogen interactions have important implications for the design of new antimicrobial agents to treat chronic infections such as tuberculosis (TB), which is notoriously refractory to conventional drug therapy. In the mouse model of TB, ...
A minidevice for performing gel-free proteome prefractionation via conventional IEF in soluble carrier ampholyte buffers is reported here. It consists of a compact block of poly-oxymethylene in which eight samples and two electrode chambers are machined. E ...
Electron transport in electrochem. polymd. films of a bithienyl-substituted {Os(tpy)2} complex has been studied. The voltammetric response assocd. with the Os2+/3+ process is unusually ideal under both semi-infinite linear and finite, diffusion conditions. ...
