Title: Effects of electron acceptors and donors on transformation of tetrachloromethane by Shewanella putrefaciens MR-1.

Authors: Petrovskis, E A; Vogel, T M; Adriaens, P

Published In FEMS Microbiol Lett, (1994 Sep 01)

Abstract: Transformation of chlorinated aliphatic compounds was examined in Shewanella putrefaciens strain MR-1, an obligately respiring facultative anaerobe. Under anaerobic conditions, MR-1 has been shown to transform tetrachloromethane to trichloromethane (24%), CO2 (7%), cell-bound material (50%) and unidentified nonvolatile products (4%). The highest rate and extent of transformation were observed with MR-1 cells grown under iron(III)-respiring conditions. Lactate, formate and hydrogen were the most effective electron donors. Tetrachloromethane was not degraded in the presence of oxygen. Transformation of other chlorinated methanes and ethenes was not observed.
