Regulation of Polyhydroxybutyrate Synthesis in the Soil Bacterium Bradyrhizobium diazoefficiens.
Polyhydroxybutyrate (PHB) is a carbon and energy reserve polymer in various prokaryotic species. We determined that, when grown with mannitol as the sole carbon source, Bradyrhizobium diazoefficiens produces a homopolymer composed only of 3-hydroxybutyrate units (PHB). Conditions of oxygen limitation (such as microoxia, oxic stationary phase, and bacteroids inside legume nodules) were permissiv...
متن کاملRequirements for Efficient Thiosulfate Oxidation in Bradyrhizobium diazoefficiens
One of the many disparate lifestyles of Bradyrhizobium diazoefficiens is chemolithotrophic growth with thiosulfate as an electron donor for respiration. The employed carbon source may be CO₂ (autotrophy) or an organic compound such as succinate (mixotrophy). Here, we discovered three new facets of this capacity: (i) When thiosulfate and succinate were consumed concomitantly in conditions of mix...
متن کاملAnaerobic Reduction of Nitrate to Nitrous Oxide Is Lower in Bradyrhizobium japonicum than in Bradyrhizobium diazoefficiens
When soil oxygen levels decrease, some bradyrhizobia use denitrification as an alternative form of respiration. Bradyrhizobium diazoefficiens (nos+) completely denitrifies nitrate (NO3-) to dinitrogen, whereas B. japonicum (nos-) is unable to reduce nitrous oxide to dinitrogen. We found that anaerobic growth with NO3- as the electron acceptor was significantly lower in B. japonicum than in B. d...
متن کاملSwimming performance of Bradyrhizobium diazoefficiens is an emergent property of its two flagellar systems.
Many bacterial species use flagella for self-propulsion in aqueous media. In the soil, which is a complex and structured environment, water is found in microscopic channels where viscosity and water potential depend on the composition of the soil solution and the degree of soil water saturation. Therefore, the motility of soil bacteria might have special requirements. An important soil bacteria...
متن کاملComplete Genome Sequence of Bradyrhizobium diazoefficiens USDA 122, a Nitrogen-Fixing Soybean Symbiont
We report the complete genome sequence of Bradyrhizobium diazoefficiens USDA 122, a nitrogen-fixing soybean symbiont. The genome consists of a 9.1 Mb circular chromosome, and 8,551 coding sequences (CDSs) were predicted on the genome. The sequence will provide insight into the evolution of rhizobial genome, and the symbiotic compatibility with host plants.
