    Abstract

    The genes encoding toluene dioxygenase, toluene cis-glycol dehydrogenase and catechol 2,3-oxygenase from Pseudomonas putida NCIB11767 were cloned and expressed in Escherichia coli HB101 on a 20 kb fragment. The recombinant strain produced indigo and a variety of other coloured products. Although the enzymes were expressed in the absence of inducers, further induction was observed in the presence of toluene or benzene, implying the presence of regulatory elements on the 20 kb insert.
