Energetic consequences of nitrite stress in Desulfovibrio vulgaris Hildenborough, inferred from global transcriptional analysis
Article Abstract:
Desulfovibrio vulgaris Hildenborough was used as a model organism to study stress response to nitrite, an important intermediate in nitrogen cycle in order to understand the metabolism of microorganisms under adverse environmental conditions for improved bioremediation efforts. Global trnscription profiling with whole-genome microarays revealed coordinated cascades of responses to nitrite in pathways of energy metabolism, nitrogen metabolism, oxidative stress response and iron homeostasis.

Microbial diversity in water and sediment of Lake Chaka, and Athalassohaline Lake in Northwestern China
Article Abstract:
Culture dependent and independent techniques were employed to study microbial diversity in Lake Chaka, a unique hypersaline lake in northwest China. The observed changes in the microbial community structure across the water-sediment interface were correlated with a decrease in salinity from the lake water to the sediments and across the interface the redox state also changed from oxic to anoxic having contributed to the observed shift in the microbial community.

Alkaline anaerobic respiration: isolation and characterization of a novel alkaliphilic and metal-reducing bacterium
Article Abstract:
The isolation and partial characterization of a novel alkaliphilic microorganism that can reduce metals at pH values up to 11.0 in the presence of elevated salt levels are reported. The isolation and activity of metal-reducing bacteria from borax-contaminated lechate ponds suggest that bioremediation of metal-contaminated alkaline environments are feasible and have implications for alkaline anaerobic respiration.
