Article Abstract:
A random library of Escherichia coli MG1655 genomic fragments fused to a promoterless green fluorescent protein (GFP) gene is constructed and screened by differential fluorescence induction for promoters that are induced after exposure to a sublethal high hydrostatic pressure stress. The findings suggest a causative relationship between the expression of heat shock proteins and pressure resistance in E.coli, emphasizing proteome alteration the primary target of inactivation by pressure.

Article Abstract:
Research was conducted to determine whether aerobic growth on nitroglycerin (GTN) is the sole nitrogen, carbon and energy source by a mixed bacterial culture. Other objectives were to investigate whether bacterial cultures could mediate complete GTN denitration and to conduct a preliminary analysis of GTN denitration kinetics. Results indicate a reductive denitration mechanism as shown by the denitration of GTN that led to the release of primarily nitrite-N.

Article Abstract:
Escherichia coli is a consistent and predominant facultative inhabitant of the human gastrointestinal tract. An isolation and description of the strain diversity of an E. coli population retrieved from a long-term operating bovine feedlot by employing a whole-genome fingerprinting technique is done.
