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

Inulinase (β-2,1-D- fructan fructanohydrolase), EC 3.2.1.7, targets the β-2,1 linkage of inulin, a polyfructan consisting of linear β-2,1 linked fructose, and hydrolyzes it into fructose. This use provides an alternative to produce fructose syrup through the hydrolysis of inulin. The

Though some genetic features of lactobacillar fructan hydrolases were elucidated, information about their enzymology or mutational analyses were scarce. Lactobacillus casei IAM1045 exhibits extracellular activity degrading inulin. After partial purification of the inulin-degrading protein from the spent culture medium, several
