木聚糖酶（EC 3.2.1.8）主要由微生物产生，能催化水解木聚糖，也称为戊聚糖酶或半纤维素酶。该酶可分解酿造或饲料工业中的原料细胞壁及β-葡聚糖，降低酿造过程中物料的粘度，促进有效物质的释放；同时可降低饲料中的非淀粉多糖，促进营养物质吸收利用，因此广泛应用于酿造和饲料工业。酸性木聚糖酶（ACX）一般分离自耐酸的真菌、细菌及部分霉菌。 本试剂盒的测定原理为：ACX在酸性环境中催化木聚糖降解为还原性寡糖和单糖；还原糖在沸水浴条件下与3,5-二硝基水杨酸（DNS）发生显色反应，生成在540 nm处具有特征吸收峰的有色产物。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540 nm处吸光度的增加速率，即可计算ACX的酶活力。
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 degrades cell wall components and β‑glucan in raw materials used in the brewing and feed industries, reducing mash viscosity, promoting the release of active substances, and reducing non‑starch polysaccharides in feed to enhance nutrient absorption. It is therefore widely used in both industries. Acid xylanase (ACX) is typically isolated from acid‑tolerant fungi, bacteria, and certain molds. Assay principle: ACX hydrolyzes xylan into reducing oligosaccharides and monosaccharides under acidic conditions. These reducing sugars react with 3,5‑dinitrosalicylic acid (DNS) in a boiling water bath, producing a colored product with a characteristic absorption peak at 540 nm. The color intensity is proportional to the amount of reducing sugars generated. ACX activity is calculated by measuring the rate of increase in absorbance at 540 nm.
