A good proportion of Sreptomyces isolates from natural sources produced extracellular xylan hydrolase. Nineteen isolated showing high activity were able to completely or partially degrade wheat bran in the growth medium. Chromatographic analysis of commercial xylan degradation products suggested that the isolates produced either endo- or exo-xylan hydrolases or their mixtures. Mixed additions of culture fluids showed a highly synergistic effect, up to an increase by 200%. In a few cases antagonism was seen which, however, could be removed by dialysis of the culture fluid.
从天然来源分离出的链霉菌中有相当一部分能产生胞外木聚糖水解酶。19株显示出高活性的菌株能够在生长培养基中完全或部分降解麦麸。对商业木聚糖降解产物的色谱分析表明，这些菌株产生的要么是内切木聚糖水解酶，要么是外切木聚糖水解酶，或者是它们的混合物。混合添加培养液显示出高度的协同效应，增幅高达200%。在少数情况下观察到拮抗作用，不过，通过对培养液进行透析可以消除这种拮抗作用。
