Beverages, 2022 Much attention has recently been paid to β-Galactosidases (β-D-galactoside galactohidrolase; EC 3.2.1.23), commonly known as lactases, due to the lactose intolerance of the human population and the importance of dairy products in the human diet.

Introducing transgalactosylation activity into a family 42 β-galactosidase [PDF]
Glycobiology, 2017 Chemo-enzymatic synthesis of oligosaccharides exploits the diversity of glycosidases and their ability to promote transglycosylation reactions in parallel with hydrolysis. Methods to increase the transglycosylation/hydrolysis ratio include site-directed mutagenesis and medium modification.

Clinical Detection and Management of Colorectal Cancer Concerning the Gut Microbiome. [PDF]
Scientifica (Cairo)Colorectal cancer (CRC) is a prevalent malignancy worldwide and a leading cause of cancer‐related mortality, influenced by both genetic predisposition and environmental factors. Gut dysbiosis, characterized by an imbalance in the gut microbiome, has been identified as a significant contributor to CRC progression. Although considerable progress has been

β-Galactosidase with transgalactosylation activity from Lactobacillus fermentum K4 [PDF]
Journal of Dairy Science, 2011 The LacLM β-galactosidase of Lactobacillus fermentum K4 is encoded by 2 consecutive genes, lacL (large subunit) and lacM (small subunit), that share 17 overlapping nucleotides. Phylogenetic analysis revealed that this enzyme was closely related to other Lactobacillus β-galactosidases and provided significant insight into its common and distinct ...

Physiologia Plantarum, Volume 175, Issue 6, November/December 2023., 2023 Abstract Terrestrialization by photosynthetic eukaryotes took place in the two branches of green microalgae: Chlorophyta and Charophyta. Within the latter, the paraphyletic streptophytic algae divide into two clades. These are named Klebsormidiophyceae‐Chlorokybophyceae‐Mesostigmatophyceae (KCM), which is the oldest, and Zygnematophyceae ...

Production of rubusoside derivatives by transgalactosylation of various .BETA.-galactosidases. [PDF]
Agricultural and Biological Chemistry, 1989 Rubusoside derivatives by transgalactosylation of various β-galactosidases were isolated and their structures were analyzed. Escherichia coli β-galactosidase produced mainly 13-O-β-d-glucosyl-19-O-[β-d-galactosyl-(1→6)-β-d-glucosyl]-steviol (RGal-2).

Comprehensive Reviews in Food Science and Food Safety, Volume 22, Issue 4, Page 2611-2651, July 2023., 2023 Abstract Prebiotics have long been used to modulate the gut microbiota and improve host health. Most established prebiotics are nondigestible carbohydrates, especially short‐chain oligosaccharides. Recently, gluco‐oligosaccharides (GlcOS) with 2–10 glucose residues and one or more O‐glycosidic linkage(s) have been found to exert prebiotic potentials ...

Nondairy food applications of whey and milk permeates: Direct and indirect uses
Comprehensive Reviews in Food Science and Food Safety, Volume 22, Issue 4, Page 2652-2677, July 2023., 2023 Abstract Permeates are generated in the dairy industry as byproducts from the production of high‐protein products (e.g., whey or milk protein isolates and concentrates). Traditionally, permeate was disposed of as waste or used in animal feed, but with the recent move toward a “zero waste” economy, these streams are being recognized for their potential ...

Chemie Ingenieur Technik, Volume 95, Issue 5, Page 767-772, May 2023., 2023 Compared to conventional enzymatic batch mode, (semi‐)continuous processes open up a more economical and ecological efficient process. Mechanical and thermal long‐term stability of the enzyme are required and were investigated in a multi‐cycle process with an enzymatic membrane reactor to synthesize prebiotic galacto‐oligosaccharides.
