Both species,
Dehalococcoides ethenogenes and
Dehalogenimonas lykanthroporepellens are irregular
coccus (coccoid) bacteria capable of
dehalogenating polychlorinated aliphatic alkanes and alkenes, such as
tetrachloroethene,
trichloropropane,
trichloroethane,
dichloropropane, and
dichloroethane. One of the features of the members of the phylum
Chloroflexota is the unusual
cell wall structure, which is
monoderm but with great variation in presence or structure of the
peptidoglycan resulting in many members staining
Gram-negative and other
Gram-positive. Both species of Dehalococcoidetes stain
Gram negative, but they potentially lack peptidoglycan and instead possess pseudopeptidoglycan (S-layer) (resistant to peptidoglycan-attacking antibiotics
ampicillin and
vancomycin;
wheat germ agglutinin does not bind nor does
lysozyme work). ==See also==
