Depression of Lactose Hydrolysis by Yeasts [PDF]

Journal of Medical Microbiology, 1977
To investigate the role that the known disaccharidase depression may play in the aetiology of infant gastroenteritis caused by Candida albicans, C. albicans and the rarely pathogenic, Saccharomyces cerevisiae were studied by three different methods. Both types of yeast significantly depressed the lactose-hydrolysis activity of beta-galactosidase, and ...

The quality indicators of ice cream upon the enzymatic hydrolysis of lactose

Пищевые системы, 2023
Ice cream is a popular type of dairy foods containing up to 6% of lactose. In connection with the lactose intolerance by many consumers and the possibility of its crystallization during storage of finished products, there is a need for a decrease in the ...

Theoretical analysis of concentration of lactose hydrolysis in a packed bed reactor using immobilized β-galactosidase

Ain Shams Engineering Journal, 2018
A theoretical analysis of concentration of lactose hydrolysis in a packed bed reactor using immobilized β-galactosidase was discussed. The model is based on system of reaction diffusion equations containing a non-linear term related to Michalies-Menten ...

Hydrolysis of lactose by immobilized microorganisms [PDF]

Applied and Environmental Microbiology, 1977
Cells of Lactobacillus bulgaricus, Escherichia coli, and Kluyveromyces (Saccharomyces) lactis immobilized in polyacrylamide gel beads retained 27 to 61% of the beta-galactosidase activity of intact cells. Optimum temperature and pH and thermostability of these microbial beta-galactosidases were negligibly affected by the immobilization.

Configuration of a Bioreactor for Milk Lactose Hydrolysis [PDF]

Journal of Dairy Science, 2003
Permeabilized microbial cells can be used as a crude enzyme preparation for industrial applications. Immobilization and process recycling can compensate for the low specific activity of this preparation. For biomass immobilization, the common support is alginate beads; however, its low surface area and the low biomass concentration limit the activity ...

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.

A Comprehensive Bioprocessing Approach to Foster Cheese Whey Valorization: On-Site β-Galactosidase Secretion for Lactose Hydrolysis and Sequential Bacterial Cellulose Production

Fermentation, 2021
Cheese whey (CW) constitutes a dairy industry by-product, with considerable polluting impact, related mostly with lactose. Numerous bioprocessing approaches have been suggested for lactose utilization, however, full exploitation is hindered by strain ...
