General description
Inulinases are classified as exoinulinases and endoinulinases.
Application
Inulinase from Aspergillus niger has been used as a glycoside hydrolase (GH) to study its potential to disperse bacteria (P. aeruginosa and S. aureus) from microbial biofilms using a polymicrobial well-plate model.
Biochem/physiol Actions
Inulinase hydrolyses inulin to produce oligosaccharides and liberate fructose. It also splits the terminal fructose units into sucrose and raffinose.
Inulinase is used in high-fructose syrup, which has therapeutic applications. Inulinase is reported to have high activity toward sucrose.
Other Notes
1 U corresponds to the amount of enzyme which releases 1 μmol of reducing sugar (measured as fructose) per minute at pH 4.1 and 37°C from inulin

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)
