Abstract
A tetrachloroethylene (PCE)-degrading gram-positive, endospore forming, ana erobic bacterium, strain DPH-1, was isolated from a contaminated site. The organism was identified as Clostridium bifermentans by 16S rRNA gene sequen ce analysis and based on its physiological characteristics. Strain DPH-1 co uld dechlorinate high concentrations of PCE (0.9 mM), via trichloroethylene (TCE) to cis-1,2-dichloroethylene (cDCE) at a rate of 0.43 mu mol/h mg pro tein, as well as a number of other halogenated aliphatic compounds.
