Description générale

A product of Novozymes Corp.
Dextranase is generated by many microorganisms, including bacteria, filamentous fungi, and yeast.

Application

Dextranase from Chaetomium erraticum has been used:
  • in microcarrier dissolution to produce multicellular 3D spheroids for drug discovery
  • in in vitro digestion of extracellular polysaccharide (EPS) from the bacterial isolates
  • in a study to investigate the immobilization of dextranase
  • to investigate the optimization of process conditions for enzymatic modification of alternan

Actions biochimiques/physiologiques

Dextranase is an endodextranase that hydrolyzes α-(1,6)-glycosidic linkages in dextran. It has many industrial and clinical applications such as food processing, sugar modification, and medicine preparation. Dextranase is widely used to produce alternated sugar beet and isomaltooligosaccharides (IMOs), a prebiotic functional food. The low molecular weight dextran obtained from dextranase serves as a synthetic blood volume expander. Dextranase can be coupled to antibodies for the detection of tumor cells. It prevents the occurrence of dental plaques by depolymerizing microbial dextran deposits in teeth. Hence, it is used in dental care products.

Notes préparatoires

A fungal dextranase produced by submerged fermentation of Chaetomium erraticum.

Remarque sur l'analyse

Stable in the pH range of 3-7 and at temperatures up to approx. 70 °C. For most applications, the preferred conditions are pH 5-6 and a temperature of 50-60 °C.

In order to facilitate the Co-Immobilization of dextransucrase and dextranase, various techniques for the immobilization of industrial endo-dextranase from Chaetomium erraticum (Novozymes A/S) were researched. Adsorption isotherms at various pH-values have been determined for bentonite (Montmorillonite), hydroxyapatite and Streamline DEAE.
