Examination of genome homogeneity in prokaryotes using genomic signatures. [PDF]
BACKGROUND:DNA word frequencies, normalized for genomic AT content, are remarkably stable within prokaryotic genomes and are therefore said to reflect a "genomic signature." The genomic signatures can be used to phylogenetically classify organisms from ...

Systems analysis of transcription factor activities in environments with stable and dynamic oxygen concentrations. [PDF]
Understanding gene regulation requires knowledge of changes in transcription factor (TF) activities. Simultaneous direct measurement of numerous TF activities is currently impossible.

A mathematical model of metabolism and regulation provides a systems-level view of how Escherichia coli responds to oxygen [PDF]
The efficient redesign of bacteria for biotechnological purposes, such as biofuel production, waste disposal or specific biocatalytic functions, requires a quantitative systems-level understanding of energy supply, carbon, and redox metabolism.

Shewanella oneidensis arcA Mutation Impairs Aerobic Growth Mainly by Compromising Translation
Arc (anoxic redox control), one of the most intensely investigated two-component regulatory systems in γ-proteobacteria, plays a major role in mediating the metabolic transition from aerobiosis to anaerobiosis.

Medium alkalization due to carbon metabolism is largely responsible for inhibition of bacterial growth by Vibrio cholerae supernatants [PDF]
Vibrio cholerae is the causative agent of the diarrheal disease cholera. Many Vibrio species secrete antimicrobial factors, though the identity of such a factor has not been determined for any V. cholerae strain.

Time dynamics of the Bacillus cereus exoproteome are shaped by cellular oxidation
At low density, Bacillus cereus cells release a large variety of proteins into the extracellular medium when cultivated in pH-regulated, glucose-containing minimal medium, either in the presence or absence of oxygen. The majority of these exoproteins are

Identification and biotechnological characterization of lactic acid bacteria isolated from chickpea sourdough in northwestern Argentina [PDF]
Chickpea, a relevant legume worldwide, can be nutritional and functionally improved by fermentation with lactic acid bacteria (LAB). In order to select suitable autochthonous starter cultures, we isolated and identified LAB from kabuli chickpeas ...
