摘要
A xylanase (X) from a Bacillus strain that is active at pH 5-10 and between temps. of 50-80 degrees C, is new. Also claimed are: (i) a culture of Bacillus sp 720/1; (ii) a DNA encoding (X); (iii) an expression vector or chromosomal integration vector containing the DNA of (ii); (iv) a strain transformed with the vector of (iii); (v) an enzyme composition contg. (X) and at least one additive; (vi) a promoter sequence derived from the gene encoding B. pumilus PRL B12 xylanase; and (vii) a presequence derived from the gene encoding B. pumilus PRL B12 xylanase.
