用葡萄糖做标准曲线。以每mL上清液每小时分解产生1 mg葡萄糖作为一个

Use glucose as a standard curve. One unit of enzyme activity (U) was decomposed to produce 1 mg of glucose per mL of supernatant per hour. Enzyme activity was expressed as U·g-1 FW. According to the difference between the absorbance values ​​of the reaction solution in the sample tube and the reaction solution in the control tube, the corresponding mass of glucose is found on the standard curve, and 1 glucose is generated by enzymatic decomposition of laminarin in each gram of sample per second as a β-1,3 Glucanase activity unit, the unit is 1mol/sg

Use glucose as the standard curve. Each ml of supernatant is decomposed every hour to produce 1 mg glucose as an enzyme activity unit (U). The enzyme activity was expressed as u · g-1 FW. According to the difference between the absorbance values of the reaction solution of the sample tube and the reaction solution of the control tube, find out the corresponding glucose quality on the standard curve, and take 1 glucose produced by enzymatic decomposition of laminarin per gram of sample per second as an example β- 1,3 glucanase activity unit, the unit is 1mol / S.G
