General description
菊粉酶分为外菊粉酶和内菊粉酶。
Application
黑曲霉菊粉酶已作为糖苷水解酶（GH），以便研究利用多微生物孔板模型从微生物生物膜上分散细菌（铜绿假单胞菌和金黄色葡萄球菌）的可能性。
Biochem/physiol Actions
菊粉酶水解菊粉，产生寡糖并释放果糖。它还能将蔗糖和棉子糖的末端果糖单元分离。
菊粉酶用于高果糖糖浆，具有治疗用途。据报道菊粉酶对蔗糖有很高的活性。
Other Notes
1个酶活力单位（U）相当于在pH 4.1和37°C下每分钟从菊粉中释放1 μmol还原糖（按果糖测量）所需的酶量

Inulin is a polysaccharide composed mainly of D-fructose units and is the most reliable indicator of the glomerular filtration rate. We have proposed an inulin detection method that involves the hydrolysis of inulin to D-fructose using inulinase and the selective

Among issues susceptible to hamper a reliable measurement of inulin clearance, those regarding the dosage of inulin are largely neglected. We have compared the analytical performances of 2 commonly used methods of inulin dosage (one "acid" and one "enzymatic" method)
