The overexpression of the rubber-cleaving dioxygenase Lcp1VH2 in Escherichia coli using an auto induction medium was described A two steps salting out precipitation with ammonium sulfate was developed for the purification of Lcp1VH2. Oligo(cis-1,4-isoprene) molecules were obtained by using the partially purified Lcp1VH2.
