The family Rhizobiaceae includes many genera of soil bacteria, often isolated for their association with plants. Herein, we investigate the genomic diversity a group Rhizobium species and unclassified strains from atypical environments, including seawater, rock matrix or polluted soil. Based on whole-genome similarity core genome phylogeny, show that this corresponds to genus Pseudorhizobium. W...
The chemolithoautotroph NT-26 oxidizes arsenite to arsenate by using a periplasmic arsenite oxidase. Purification and preliminary characterization of the enzyme revealed that it (i) contains two heterologous subunits, AroA (98 kDa) and AroB (14 kDa); (ii) has a native molecular mass of 219 kDa, suggesting an alpha2beta2 configuration; and (iii) contains two molybdenum and 9 or 10 iron atoms per...
Thermithiobacillus tepidarius DSM 3134 was originally isolated (1983) from the waters of a sulfidic spring entering the Roman Baths (Temple of Sulis-Minerva) at Bath, United Kingdom and is an obligate chemolithoautotroph growing at the expense of reduced sulfur species. This strain has a genome size of 2,958,498 bp. Here we report the genome sequence, annotation and characteristics. The genome ...
The nitrifying bacterium Nitrosomonas europaea can obtain all its carbon for growth from CO(2) and all its energy and reductant for growth from the oxidation of NH(3) and is considered an obligate chemolithoautotroph. Previous studies have shown that N. europaea can utilize limited amounts of certain organic compounds, including amino acids, pyruvate, and acetate, although no organic compound h...
Nitrosomonas europaea (ATCC 19718) is a gram-negative obligate chemolithoautotroph that can derive all its energy and reductant for growth from the oxidation of ammonia to nitrite. Nitrosomonas europaea participates in the biogeochemical N cycle in the process of nitrification. Its genome consists of a single circular chromosome of 2,812,094 bp. The GC skew analysis indicates that the genome is...
Abstract Shallow-water hydrothermal vents are extreme environments characterized by high temperatures, low pH, and CO 2 concentrations; therefore, they considered as suitable laboratories for studying the effect of global changes on marine microbes. We hypothesized a direct prokaryotic community structure functioning in Panarea Island’s system. Sampling was conducted along 9-station transect th...
