title: Isolation and characterization of Dechlorospirillum anomalous strain JB116 from a sewage treatment plant.
abstract: The dissimilatory perchlorate reducers mainly belong to two monophyletic groups, viz. Dechloromonas and Azospira in the beta subclass of Proteobacteria. The present study describes isolation and genetic characterization of Dechlorospirillum anomalous strain JB116 that belongs to alpha subclass of Proteobacteria. The strain JB116 was isolated under facultative anaerobic conditions on a growth medium containing sodium perchlorate and sodium acetate as electron (e(-)) acceptor and e(-) donor, respectively. The strain is a spirillum shaped, dissimilatory perchlorate and nitrate reducer that prefers nitrate to perchlorate. It grows heterotrophically with acetate at temperatures between 25-35 degrees C, NaCl concentrations between 0-0.5% and pH of 7-7.8. The strain JB116 is the second only representative strain within D. anomalous that shares 99% 16S rDNA sequence similarity with the type strain D. anomalous strain WD.
