Identification and expression of benzylsuccinate synthase genes in a toluene-degrading methanogenic consortium.
Benzylsuccinate synthase (BSS) initiates anaerobic toluene biodegradation, and BSS genes have been found in several nitrate- and iron-reducing organisms. Here, two new putative bssA genes were identified in a methanogenic toluene-degrading culture. Transcription was upregulated with toluene but not with benzoate, consistent with the proposed function. These are the first bss sequences from a me...
متن کاملDraft Genome Sequence of Magnetospirillum sp. Strain 15-1, a Denitrifying Toluene Degrader Isolated from a Planted Fixed-Bed Reactor
Here, we report the draft genome sequence of Magnetospirillum sp. 15-1. This strain was isolated from a planted fixed-bed reactor based on its ability to degrade toluene under anaerobic conditions. The genome assembly consists of 5.4 Mb in 28 contigs and 5,095 coding sequences containing the genes involved in anaerobic toluene degradation.
متن کاملIsolation and characterization of Magnetospirillum sp. strain 15-1 as a representative anaerobic toluene-degrader from a constructed wetland model
Previously, Planted Fixed-Bed Reactors (PFRs) have been used to investigate microbial toluene removal in the rhizosphere of constructed wetlands. Aerobic toluene degradation was predominant in these model systems although bulk redox conditions were hypoxic to anoxic. However, culture-independent approaches indicated also that microbes capable of anaerobic toluene degradation were abundant. Ther...
متن کاملAn iron-regulated gene, magA, encoding an iron transport protein of Magnetospirillum sp. strain AMB-1.
Magnetospirillum sp. AMB-1 is a freshwater magnetic bacterium which synthesizes intracellular particles of magnetite (Fe3O4). A genomic DNA fragment required for synthesis of magnetic particles was previously isolated from a nonmagnetic transposon Tn5 mutant. We have determined the complete nucleotide sequence of this fragment. The 2975-base pair region contains two putative open reading frames...
متن کاملAnaerobic degradation of aromatic compounds by magnetospirillum strains: isolation and degradation genes.
Four Magnetospirillum strains degrading toluene, phenol, benzoate, and other aromatic compounds under anaerobic conditions were isolated from denitrifying enrichment cultures. One of the isolates, toluene-degrading strain TS-6, contained genes that are homologous to those encoding benzylsuccinate synthase (Bss) and benzoyl-CoA reductase (Bcr), two key enzymes of anaerobic toluene and benzoate d...
