Metabolic adaptation and trophic strategies of soil bacteria - C1- metabolism and sulfur chemolithotrophy in Starkeya novella

open access: yesFrontiers in Microbiology, 2013
The highly diverse and metabolically versatile microbial communities found in soil environments are major contributors to the global carbon, nitrogen and sulfur cycles. We have used a combination of genome –based pathway analysis with proteomics and gene

Continuous chemotrophic growth and respiration of Chromatiaceae species at low oxygen concentrations [PDF]

open access: yes, 1992
Endogenous and maximum respiration rates of nine purple sulfur bacterial strains were determined. Endogenous rates were below 10 nmol O2 · (mg protein · min)-1 for sulfur-free cells and 15–35 nmol O2 · (mg protein · min)-1 for cells containg ...
