Complete genome sequence of Syntrophobacter fumaroxidans strain (MPOB(T)).

Syntrophobacter fumaroxidans strain MPOB(T) is the best-studied species of the genus Syntrophobacter. The species is of interest because of its anaerobic syntrophic lifestyle, its involvement in the conversion of propionate to acetate, H2 and CO2 during the overall degradation of organic matter, and its release of products that serve as substrates for other microorganisms. The strain is able to ferment fumarate in pure culture to CO2 and succinate, and is also able to grow as a sulfate reducer with propionate as an electron donor. This is the first complete genome sequence of a member of the genus Syntrophobacter and a member genus in the family Syntrophobacteraceae. Here we describe the features of this organism, together with the complete genome sequence and annotation. The 4,990,251 bp long genome with its 4,098 protein-coding and 81 RNA genes is a part of the Microbial Genome Program (MGP) and the Genomes to Life (GTL) Program project

Draft Genome Sequence of Mn(II)-Oxidizing Bacterium Oxalobacteraceae sp. Strain AB_14.

Biological Mn(II) oxidation produces reactive manganese oxides that help to mitigate metal contamination in the environment. Here, we present the genome of Oxalobacteraceae sp. strain AB_14, a species of Mn(II)-oxidizing bacteria (MOB) that is notable for its ability to catalyze Mn oxidation at low pH (5.5)

Estudio de las rizobacterias del suelo de la taiga de Chernevaya en Siberia occidental y su posible efecto sobre el crecimiento de las plantas

El aislamiento de bacterias del suelo de varios ambientes con tasas de fertilidad excepcionalmente altas representa una oportunidad para identificar agentes prometedores para promover la producción agrícola. El objetivo del artículo es estudiar las densidades de bacterias cultivables y aislar bacterias de la rizosfera del rábano y el trigo de primavera. Las plantas se cultivaron en el experimento en maceta con suelo Chernevaya virgen, que poseía una productividad extraordinaria, y suelo forestal zonal que no demostró características similares. Se purificaron cincuenta y nueve aislados bacterianos y se evaluaron sus efectos beneficiosos sobre el crecimiento temprano del trigo. Los aislados pertenecían a los filos Proteobacteria, Actinobacteria y Firmicutes, y los géneros más representados fueron Pseudomonas , Streptomyces , Paenibacillus y Methylobacterium . Estas bacterias dominantes se utilizaron en estudios de inoculación de plantas. Las cepas promovieron un aumento significativo en la longitud y biomasa de los brotes y las raíces, por lo que pueden considerarse rizobacterias promotoras del crecimiento de las plantas [PGPR]. En cuanto a los ensayos de biotest, se seleccionaron cepas que mostraron altas capacidades de promoción del crecimiento de las plantas [PGP] para una mayor investigación. Este estudio contribuyó a aislar bacterias de un entorno natural único con potencial biotecnológico para mejorar el crecimiento de las plantas y mostró potencia para ser explotadas como bioinoculantes

Complete genome sequence of Meiothermus silvanus type strain (VI-R2).

Meiothermus silvanus (Tenreiro et al. 1995) Nobre et al. 1996 belongs to a thermophilic genus whose members share relatively low degrees of 16S rRNA gene sequence similarity. Meiothermus constitutes an evolutionary lineage separate from members of the genus Thermus, from which they can generally be distinguished by their slightly lower temperature optima. M. silvanus is of special interest as it causes colored biofilms in the paper making industry and may thus be of economic importance as a biofouler. This is the second completed genome sequence of a member of the genus Meiothermus and only the third genome sequence to be published from a member of the family Thermaceae. The 3,721,669 bp long genome with its 3,667 protein-coding and 55 RNA genes is a part of the Genomic Encyclopedia of Bacteria and Archaea project
