Summary The xylanase gene of Cellulomonas sp. NCIM 2353 was cloned in pUC 18 and selected by growth on xylan as the sole carbon source. The functional clone harboured the recombinant plasmid with an insert of 1.42 kbp, as determined by restriction mapping and Southern hydridization. The clone secreted a xylanase of 45 000 mol. wt. as determined by Western blot analysis using specific antixylanase antibodies. The DNA insert carried the full structural gene along with its promoter and possibly regulatory sequences, since xylanase activity in the clone Cs11 was inducible by xylan.
