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 is used in high-fructose syrup, which has therapeutic applications. Inulinase is reported to have high activity toward sucrose.
Inulinase hydrolyses inulin to produce oligosaccharides and liberate fructose. It also splits the terminal fructose units into sucrose and raffinose.
Unit Definition
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
