Strain TT4B has been isolated from anaerobic sediments known to be
contaminated with a variety of organic solvents. It is a gram-negative,
rod-shaped bacterium and grew anaerobically with acetate as the electron
donor and tetrachloroethylene as the electron acceptor in a mineral medium.
cis-Dichloroethylene was the halogenated product. This strain did not grow
fermentatively and used only acetate or pyruvate as electron donors.
Tetrachloroethylene and trichloroethylene were used as electron acceptors,
as were ferric nitriloacetate and fumarate. Nitrogen and sulfur oxyanions
were not able to substitute as the electron acceptor for this organism.
Modest growth occurred in a two- phase system with 1 ml of hexadecane
containing 50 to 200 mM tetrachloroethylene (aqueous concentrations, 25 to
100 microM) and 10 ml of anaerobic mineral solution with Na2S as the
reducing agent. Growth was completely inhibited at tetrachloroethylene
levels above 100 microM.
