Effect of carbon and nitrogen sources on CMCase production by the strain ME27-1. (a) Different carbon sources: 1∼9 represented glycerol, lactose, sucrose, maltose, CMC-Na, filter paper, Avicel, soluble starch, and wheat bran, respectively. (b) The concentration of wheat bran. (c) Different nitrogen sources: a∼j represented (NH₄)₂SO₄, NH₄NO₃, NaNO₃, KNO₃, NH₄Cl, urea, soybean, yeast extract, tryptone, and beef extract, respectively. (d) The concentration of NH₄Cl.
