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.

Antigenicity of a viral peptide displayed on β-galactosidase fusion proteins is influenced by the presence of the homologous partner protein [PDF]

FEMS Microbiology Letters, 1996
Several beta-galactosidase fusion proteins have been constructed containing the entire VP1 protein from foot-and-mouth disease virus (FMDV) [Corchero et al. (1996) J. Biotechnol. in press]. The antigenicity of the major immunodominant site A (13 amino acids in length) within the VP1 protein has been studied in competitive ELISA using a panel of seven ...

Knockout mutants of Arabidopsis thaliana β-galactosidase. Modifications in the cell wall saccharides and enzymatic activities

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.

Characterization of β-galactosidase and α-galactosidase activities from the halophilic bacterium Gracilibacillus dipsosauri

Annals of Microbiology, 2021
Purpose Gracilibacillus dipsosauri strain DD1 is a salt-tolerant Gram-positive bacterium that can hydrolyze the synthetic substrates o-nitrophenyl-β-d-galactopyranoside (β-ONP-galactose) and p-nitrophenyl-α-d-galactopyranoside (α-PNP-galactose).

Whole yogurt sweetened with glucose-galactose syrup obtained by nanofiltration: Effect on galactooligosaccharides concentration, physicochemical and sensory properties

Applied Food Research, 2023
Glucose-galactose syrup is a sweetener obtained from whey. It is scarcely industrial produced due to its low level of sweetness and lower economic competitiveness compared to other traditional sugars.

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.

Safety of a change in the conditions of use of galacto‐oligosaccharides as a novel food ingredient in food supplements pursuant to Regulation (EU) 2015/2283

EFSA Journal, 2021
Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on the change in the conditions of use of galacto‐oligosaccharides (GOS) as a novel food (NF) pursuant to ...

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 ...

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
