Draft Genome Sequences of Five Strains in the Genus Thauera

Abstract

Thauera species are members of the betaproteobacteria and are most noted for their ability to metabolize aromatic compounds under anoxic conditions. Here, we announce the draft genome sequences of five Thauera strains in an effort to provide further genetic information as a resource for understanding the ecological function of this environmentally important genus.

Meta-omics approaches to understand and improve wastewater treatment systems

“…From this information, adjusting the sludge retention time and other parameters according to the wastewater characteristics in WWTPs seems of key importance to achieve satisfactory nitrification and thus avoid the formation of nitrous oxide gas Rev Environ Sci Biotechnol NAR enzyme and therefore NAP enzyme might reflect an adaptation to nitrate-limited environments, where coupling efficiency would be sacrificed in favor of substrate affinity. A similar situation occurs in five different members of the genus Thauera isolated from wastewater, whose recently sequenced genomes (Liu et al 2013) shows that Thauera sp. 27, Thauera sp.…”

“…Another adaptation example is the type of nitrite oxidoreductase (NXR) (cytoplasmic or periplasmic) In denitrifying microbes (catalyzing nitrate reduction to dinitrogen gas) (Fig. 3) the presence of two different nitrate reductases-membrane-bound nitrate reductase (NAR) and periplasmic nitrate reductase (NAP)-may also reflect an ecophysiological adaptation to the environment they inhabit (Liu et al 2013;Richardson 2000). In many of the best characterized To date, the complete genome sequences of six AOB have been deposited in public databases (Gold Database)-Nitrosomonas europaea ATCC19718 (isolated from soil), Nitrosomonas eutropha C91 (isolated from a sewage disposal plant), Nitrosomonas sp.…”

Bacterial diversity patterns of the intertidal biofilm in urban beaches of Río de la Plata

“…When environmental conditions change owing to anthropogenic activities (such as wastewater or hydrocarbons spill) those taxa that can cope with the specific situation will grow and dominate the metabolism of the biofilm. In this regard, in Montevideo Bay samples, where the DO was significantly lower than in the rest of the sites, the more abundant OTUs belonged to Thauera, which are facultatively anaerobic Betaproteobacteria characterized for the ability of several species of the genus to metabolize aromatic compounds, under either aerobic or anaerobic conditions (Ramakrishnan, 2013;Liu et al, 2013). Due to this ability of using aromatic hydrocarbons either under anoxic conditions and because it contains unique pathways for the degradation of these aromatic compounds, Thauera has emerged as an important genus with anaerobic and facultative metabolism in environmental systems.…”

Anaerobic humus and Fe(III) reduction and electron transport pathway by a novel humus-reducing bacterium, Thauera humireducens SgZ-1

“…Consequently, Thauera has emerged as an important genus in the investigation of metabolic versatility and remediation of environmental pollutants (Liu et al 2013). Recently, a novel humus-reducing bacterium, Thauera humireducens SgZ-1 (KACC 16524=CCTCC M2011497), was isolated from the anode biofilm of a sediment microbial fuel cell in our laboratory (Yang et al 2013).…”

“…Thauera species are noted for their ability to metabolize various aromatic compounds under denitrifying conditions and for using simple compounds (e.g., hydrogen and acetate) for growth (Liu et al 2013). Consequently, Thauera has emerged as an important genus in the investigation of metabolic versatility and remediation of environmental pollutants (Liu et al 2013).…”
