Identification of bacteria with β-galactosidase activity in faeces from lactase non-persistent subjects [PDF]
FEMS Microbiology Ecology, 2005 Previous studies suggest that, besides the maldigestion of lactose in the small intestine, the colonic processing of lactose might play a role in lactose intolerance. beta-Galactosidase is the bacterial enzyme which catalyzes the first step of lactose fermentation in the colon.

Biologia Plantarum, 2018 This work studied the six β-galactosidases (BGALs) of the subfamily a1 of Arabidopsis, that have been proposed to play important roles in the cell wall remodelling during plant development, although their precise functions are still unknown.

Sensory Assessment of Bi-Enzymatic-Treated Glucose-Galactose Syrup
Fermentation, 2023 There are a variety of ways to make glucose-galactose syrup (GGS) and other products of lactose hydrolysis; therefore, research is still ongoing and will undoubtedly result in improved methods and lower costs.

Lactobacillus fermentumCRL 722 is able to deliver active α-galactosidase activity in the small intestine of rats [PDF]
FEMS Microbiology Letters, 2005 alpha-galactooligosaccharides (alpha-GOS) found in legumes such as soybeans can cause gastrointestinal disorders since mammals lack alpha-galactosidase (alpha-Gal) in the small intestine which is necessary for their hydrolysis. Lactobacillus fermentum CRL 722 is a lactic acid bacterium (LAB) capable of degrading alpha-GOS due to its elevated alpha-Gal ...

Bifidobacterium breve UCC2003 metabolises the human milk oligosaccharides lacto-N-tetraose and lacto-N-neo-tetraose through overlapping, yet distinct pathways [PDF]
, 2016 In this study, we demonstrate that the prototype B. breve strain UCC2003 possesses specific metabolic pathways for the utilisation of lacto-N-tetraose (LNT) and lacto-N-neotetraose (LNnT), which represent the central moieties of Type I and Type II human ...

Potential applicaton of β-galactosidase in food science and nutrition
Acta Agriculturae Slovenica, 2017 β-galactosidase is an enzyme with hydrolytic and transgalactosylation activity. The origin of the enzyme dictates the balance between both activities.

Insertion of a 27 amino acid viral peptide in different zones ofEscherichia coliβ-galactosidase: Effects on the enzyme activity [PDF]
FEMS Microbiology Letters, 1994 Seven internal, putatively exposed regions of Escherichia coli beta-galactosidase have been explored regarding their tolerance to insertions of large foreign peptides. Small sequence modifications, including amino acid substitutions and small deletions, were introduced into the lacZ gene to generate unique BamHI restriction sites. By using these mutant
