Repression of phenol catabolism by organic acids in Ralstonia eutropha.
During batch growth of Ralstonia eutropha (previously named Alcaligenes eutrophus) on phenol in the presence of acetate, acetate was found to be the preferred substrate; this organic acid was rapidly metabolized, and the specific rate of phenol consumption was considerably decreased, although phenol consumption was not abolished. This decrease corresponded to a drop in phenol hydroxylase and ca...
متن کاملDiverse protein regulations on PHA formation in Ralstonia eutropha on short chain organic acids
Organic acids are considered as potential substrates for biosynthesis of polyhydroxyalkaonates. The acids may also be the metabolic inhibitors at moderate concentration levels. In this study, Ralstonia eutropha was used to elucidate the protein regulations when the bacterial cells pre-cultivated on glucose were exposed to three representative short chain organic acids, acetic, propionic and lev...
متن کاملProduction of fatty acids in Ralstonia eutropha H16 by engineering β-oxidation and carbon storage
Ralstonia eutropha H16 is a facultatively autotrophic hydrogen-oxidizing bacterium capable of producing polyhydroxybutyrate (PHB)-based bioplastics. As PHB's physical properties may be improved by incorporation of medium-chain-length fatty acids (MCFAs), and MCFAs are valuable on their own as fuel and chemical intermediates, we engineered R. eutropha for MCFA production. Expression of UcFatB2, ...

متن کاملThe hydrogen-sensing apparatus in Ralstonia eutropha.
Molecular hydrogen is widely used by microorganisms as a source of energy. One of the best studied aerobic hydrogen oxidizers, the beta-proteobacterium Ralstonia eutropha (formerly Alcaligenes eutrophus), harbors two distinct [NiFe]-hydrogenases which catalyze the heterolytic cleavage of H2 into 2H+ and 2e-. The genes encoding the hydrogenase subunits are arranged in two large operons together ...
