Phylogenetic analysis has shown that these bacteria are members of the<jats:italic>Proteobacteria<\/jats:italic>. Strains have been isolated from polluted and pristine sites, but only strains from polluted sites have been characterized in detail and deposited in culture collections. Herein we describe the isolation and characterization of perchlorate-reducing bacterium strain MA-1<jats:sup>T<\/jats:sup>and chlorate-reducing bacterium strain ASK-1, respectively isolated from a pristine and a chlorate-polluted site. Both isolates are members of the<jats:italic>Proteobacteria<\/jats:italic>. The 16S rRNA gene sequence similarity of MA-1<jats:sup>T<\/jats:sup>to<jats:italic>Dechloromonas agitata<\/jats:italic>DSM 13637<jats:sup>T<\/jats:sup>is 97\u00b76\u200a%, but the relatedness in DNA\u2013DNA reassociation is only 37\u200a%. Therefore, we propose to classify strain MA-1<jats:sup>T<\/jats:sup>(=DSM 15637<jats:sup>T<\/jats:sup>=ATCC BAA-776<jats:sup>T<\/jats:sup>) as the type strain of a novel species,<jats:italic>Dechloromonas hortensis<\/jats:italic>sp. nov. Strain ASK-1 and a previously described strain GR-1 show 100 and 99\u200a% 16S rRNA gene sequence similarity to<jats:italic>Pseudomonas chloritidismutans<\/jats:italic>DSM 13592<jats:sup>T<\/jats:sup>and<jats:italic>Dechlorosoma suillum<\/jats:italic>DSM 13638<jats:sup>T<\/jats:sup>, respectively. DNA\u2013DNA hybridization studies indicated that strains ASK-1 and GR-1 are related at the species level to<jats:italic>P. chloritidismutans<\/jats:italic>DSM 13592<jats:sup>T<\/jats:sup>(79\u200a%) and<jats:italic>Dechlorosoma suillum<\/jats:italic>DSM 13638<jats:sup>T<\/jats:sup>(85\u200a%), respectively. As suggested previously,<jats:italic>Dechlorosoma suillum<\/jats:italic>appears to be a later heterotypic synonym of<jats:italic>Azospira oryzae<\/jats:italic>. Although strain ASK-1 is identified as<jats:italic>P. chloritidismutans<\/jats:italic>, its morphology and growth requirements are different from those of the type strain.<\/jats:p>","DOI":"10.1099\/ijs.0.63404-0","type":"journal-article","created":{"date-parts":[[2005,9,15]],"date-time":"2005-09-15T22:53:25Z","timestamp":1126824805000},"page":"2063-2068","source":"Crossref","is-referenced-by-count":79,"title":["Dechloromonas hortensis sp. nov. and strain ASK-1, two novel (per)chlorate-reducing bacteria, and taxonomic description of strain GR-1"],"prefix":"10.1099","volume":"55","author":[{"given":"Arthur","family":"Wolterink","sequence":"first","affiliation":[{"name":"Laboratory of Microbiology, Wageningen University, Hesselink van Suchtelenweg 4, 6703 CT Wageningen, The Netherlands"}]},{"given":"Sungyoun","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Environmental Science and Engineering, Kwangju Institute of Science and Technology, Oryong-dong 1, Puk-gu, Gwangju, Korea"}]},{"given":"Margje","family":"Muusse","sequence":"additional","affiliation":[{"name":"Laboratory of Microbiology, Wageningen University, Hesselink van Suchtelenweg 4, 6703 CT Wageningen, The Netherlands"}]},{"given":"In S.","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Environmental Science and Engineering, Kwangju Institute of Science and Technology, Oryong-dong 1, Puk-gu, Gwangju, Korea"}]},{"given":"Paul J.
