木聚糖酶（EC3.2.1.8）主要由微生物产生，能催化水解木聚糖，也被称为戊聚糖酶或半纤维素酶，可分解酿造或饲料工业中的原料细胞壁以及β-葡聚糖，降低酿造中物料的粘度，促进有效物质的释放，以及降低饲料中的非淀粉多糖，促进营养物质的吸收利用，因而广泛的应用于酿造和饲料工业中，BAX 一般分离自最适生长 pH 为 9-11 的微生物。在该试剂盒中，S-BAX 在碱性环境中催化木聚糖降解成还原性寡糖和单糖，在沸水浴条件下进一步与 3,5-二硝基水杨酸发生显色反应，在 540 nm 处有特征吸收峰，反应液颜色的深浅与酶解产生的还原糖量成正比，通过测定反应液在 540 nm 吸光值增加速率，可计算 S-BAX 活力。可检测土壤样本。
Xylanase (EC 3.2.1.8) is mainly produced by microorganisms and catalyzes the hydrolysis of xylan. It is also known as pentosanase or hemicellulase. This enzyme can decompose cell walls and β‑glucan in raw materials used in the brewing and feed industries, thereby reducing the viscosity of the mash during brewing and promoting the release of active substances; meanwhile, it reduces non‑starch polysaccharides in feed, facilitating nutrient absorption and utilization. Consequently, it is widely applied in both the brewing and feed industries. Alkaline xylanase (BAX) is generally isolated from microorganisms with an optimal growth pH of 9–11. In this kit, S‑BAX catalyzes the degradation of xylan into reducing oligosaccharides and monosaccharides under alkaline conditions. The resulting reducing sugars undergo a chromogenic reaction with 3,5‑dinitrosalicylic acid (DNS) in a boiling water bath, generating a colored product with a characteristic absorption peak at 540 nm. The color intensity of the reaction solution is directly proportional to the amount of reducing sugars produced by enzymatic hydrolysis. Therefore, the S‑BAX activity can be calculated by measuring the rate of increase in absorbance at 540 nm. This kit is suitable for testing soil samples.
