Safety evaluation of an extension of use of the food enzyme β-galactosidase from the genetically modified <i>Bacillus licheniformis</i> strain NZYM-BT. [PDF]

EFSA J
Abstract The food enzyme β‐galactosidase (EC 3.2.1.23) is produced with the genetically modified Bacillus licheniformis strain NZYM‐BT by Novozymes A/S. The safety of this food enzyme was evaluated previously, and no safety concern was identified when used in one food manufacturing process.

β-Glucosidase and β-Galactosidase-Mediated Transglycosylation of Steviol Glycosides Utilizing Industrial Byproducts

Frontiers in Bioengineering and Biotechnology, 2021
Stevia rebaudiana Bertoni is a plant cultivated worldwide due to its use as a sweetener. The sweet taste of stevia is attributed to its numerous steviol glycosides, however, their use is still limited, due to their bitter aftertaste.

Transglycosylation catalysed by Caco-2 membrane disaccharidases: A new approach to understand carbohydrates digestibility

, 2023
Under appropriate experimental conditions, some glycoside hydrolases can catalyze transglycosylation reactions; a hypothesis associated with this is that the glycosidic linkages formed will be preferentially hydrolyzed under optimal conditions. Therefore,
