Note that growth with the chlorinated electron acceptors has not in all cases been conclusively demonstrated
Note that in older literature, the abbreviation “t” is used to indicate the “total” concentration of DCEs (i.e., cis-DCE, trans-DCE and 1,1-DCE). With the enhanced resolution
of newer capillary column technology the three DCE isomers can be resolved and the term “tDCE” indicates trans-DCE
