Using microcalorimetry and thermodynamic modeling to examine effects of thermal stress
Hunt KA, von Netzer F, Gorman-Lewis D, Stahl DA. (2022) Microbial maintenance energy quantified and modeled with microcalorimetry. Biotechnol Bioeng. 2022 Jun 9; [DOI]:10.1002/bit.28155. {PMID}: 35680566 OSTI:1874049 All known biology is driven by the partitioning of energy released from nutrient consumption, either into building new cells or maintaining cellular integrity required for viability. The energy […]

Whole genome sequence reveals molecular mechanisms underlying adaptation of Rhodanobacter strains to multiple stressors
The Genomic Features Underlying Adaptation of Rhodanobacter Strains to Stressful Conditions (denitrification processes, heavy metal resistance, and restriction-modification systems) present at ENIGMA Field Site ORR. Rhodanobacter species have been found dominant in the subsurface of Oak Ridge Reservation (ORR) site contaminated with acid, nitrate, metal radionuclides, and other heavy metals. Recently, multiple Rhodanobacter strains have […]
