Read the following statements regarding bioremediation
(A) . Aerobic biodegradation of PCBs is mainly carried out by the white rot fungus, Phanerochaete and by Acinetobacter and
Alcaligenes.
(B) . Methylococcus capsulatus can convert chloro- and bromo methane to formaldehyde, dichloro- and trichloro methane to
CO? while growing on methane.

good from an environmental standpoint
(D) . Burkholderia dechlorinates the pesticide 2, 4, 5-T aerobically by using oxygenase enzymes and release chloride ion
(Ch).
(E) . Reductive dechlorination is less important than oxidative dechlorination from ecological standpoint.
