Sulfur Metabolism of Hydrogenovibrio thermophilus Strain S5 and Its Adaptations to Deep-Sea Hydrothermal Vent Environment
Hydrogenovibrio bacteria are ubiquitous in global deep-sea hydrothermal vents. However, their adaptations enabling survival in these harsh environments are not well understood. In this study, we characterized the physiology and metabolic mechanisms of Hydrogenovibrio thermophilus strain S5, which was first isolated from an active hydrothermal vent chimney on the Southwest Indian Ridge. Physiolo...
متن کاملThe carbon-concentrating mechanism of the hydrothermal vent chemolithoautotroph Thiomicrospira crunogena.
Chemolithoautotrophic bacteria grow in habitats with a variety of dissolved inorganic carbon (DIC) concentrations and are likely to have transport-related adaptations to DIC scarcity. Carbon-concentrating mechanisms (CCMs) are present in many species of cyanobacteria, enabling them to grow in the presence of low concentrations of CO2 by utilizing bicarbonate transporters and CO2 traps to genera...
متن کاملRegulation of citric acid cycle by calcium.
The relationship of extramitochondrial Ca2+ to intramitochondrial Ca2+ and the influence of intramitochondrial free Ca2+ concentrations on various steps of the citric acid cycle were evaluated. Ca2+ was measured using the Ca2+ sensitive fluorescent dye fura-2 trapped inside the rat heart mitochondria. The rate of utilization of specific substrates and the rate of accumulation of citric acid cyc...
متن کاملEffect of citric acid chelating agent on morphology of ZnO particles prepared by hydrothermal method
Abstract Zinc oxide is one of the most widely used and important materials in today's science and industry. In this study, ZnO nanoparticles were synthesized by hydrothermal method. Zinc acetate, citric acid and deionized water was respectively used as a source of zinc ion, solvent and chelating agent. In this study, the effect of citric acid concentration as an additive was studied on morphol...
متن کاملCitric Acid and Bone Metabolism
From the sedimentation and diffusion constant values obtained in a solution containing 1 g./ 100 ml. H substance, and using the determined value of the partial specific volume, the molecular weight was calculated from the usual equation (Svedberg & Pedersen, 1940) giving a value of 320 000. From the same data the frictional ratio f/fo obtained was 4-2. This corresponds to an axial ratio of > 10...
