Cloning of extracellular lipase gene from Xanthomonas campestris pathovar sesami on to Escherichia coli.

A lipase gene from X. campestris pv. sesami (strain XcS 1) causal agent of leaf spot disease of Sesamum indicum, was cloned onto E. colt. XcS showed the presence of lip+ transformants on Dye's medium with 1% glycerol as sole carbon source. The recombinant plasmids were isolated and when digested with Eco R1, yielded 2 fragments with molecular weights 4.0 and 4.8 kb. Thus a 8.8 kb insert DNA fragment was obtained which showed lipase activity.
