Finally, the entrained water is expelled into the overlying water column as a hydrothermal fluid. Hydrothermal circulation occurs at all active plate boundaries like mid-ocean ridges, submarine volcanic arcs and backarc basins. They represent one of the most extreme and dynamic ecosystems on the planet with steep physico-chemical gradients. Nevertheless, these environments are characterized by exceptional high biomass representing hotspots of life in the mostly hostile and desolated deep sea. -

Analyses of the 16S rRNA gene and two functional 25 genes involved in sulfate respiration and anaerobic degradation of aromatic compounds 26 revealed that the isolate was closely related to members of the genus Desulfosarcina. 27 Strain PP31 was capable of growing on p-xylene under sulfate-reducing conditions, and 28 the ratio of generated sulfide and consumed p-xylene suggested complete oxidation by 29 the novel isolate. The strain could not grow on benzene, toluene, ethylbenzene, 30 m-xylene o-xylene, or n-hexane as an electron donor. Strain PP31 is the first isolated 31 bacterium that degrades p-xylene anaerobically, and will be useful to understanding the 32 mechanism of anaerobic degradation of p-xylene. -

So far, a variety of dechlorinating bacteria have been isolated, which contained members in diverse phylogenetic group such as genera Desulfitobacterium and “Dehalococcoides”. In this review, we introduced the up-to date knowledge of bacteria that dechlorinate aromatic chlorides and new candidate, Dehalobacter spp., as promising bacteria that dechlorinate aromatic chlorides. Keywords: reductive dehalogenation, aromatic chlorides, Dehalobacter INTRODUCTION Aromatic chlorides such as chlorinated phenols, benzenes, biphenyls, and dibenzo- p-dioxins are compounds of serious environmental concern because of their widespread use and hazardous effects for animals and plants and frequently encountered as persistent pollutants -

Variations in the Two Last Steps of the Purine Biosynthetic Pathway in Prokaryotes

Accepted: February 16, 2019 Abstract The last two steps of the purine biosynthetic pathway may be catalyzed by different enzymes in prokaryotes. The genes that encode these enzymes include homologs of purH, purP, purO and those encoding the AICARFT and IMPCH domains of PurH, here named purV and purJ, respectively. In Bacteria, these reactions are mainly catalyzed by the domains AICARFT and IMPCH of PurH. In Archaea, these reactions may be carried out by PurH and also by PurP and PurO, both considered signatures of this domain and analogous to the AICARFT and IMPCH domains of PurH, respectively. These genes were searched for in 1,403 completely sequenced prokaryotic genomes publicly available. Our analyses revealed taxonomic patterns for the distribution of these genes and anticorrelations in their occurrence. The analyses of bacterial genomes revealed the existence of genes coding for PurV, PurJ, and PurO, which may no longer be considered signatures of the domain Archaea. Although highly divergent, the PurOs of Archaea and Bacteria show a high level of conservation in the amino acids of the active sites of the protein, allowing us to infer that these enzymes are analogs.
