Abstract

Rhodococcus rhodochrous NCIMB13064 can dehalogenate and utilise a number of halogenated aliphatic compounds as sole carbon and energy source. Mutants of NCIMB13064 can be easily isolated with an enlarged range of 1-chloroalkane utilising ability. Dehalogenation of 1-chlorononane, 1-chlorodecane and short-chain 1-chloroalkanes (C-3-C-8) is encoded by the same plasmid pRTL1. However, a different genetic element(s) is required for the dehalogenation of 3-chloropropionic acid. Two derivatives (P200 and P400) of R. rhodochrous NCIMB13064 were isolated which had acquired the ability to utilise naphthalene as sole carbon and energy source. Both strains lost the ability to utilise short-chain 1-chloroalkanes and underwent some rearrangements associated with pRTL1 plasmid.
