In vitro fermentability of prebiotic oligosaccharides by lactobacilli
prebiotics utilisation lactobacilli fructooligosaccharides galactooligosaccharides lysozyme susceptibility
2014/2/26
Twelve strains of lactobacilli were tested for their growth and ability to utilise six prebiotics (pure substances and commercially available prebiotics) as a sole carbon source. All strains showed a ...
The Preparation and Bioactivity Research of Agaro-Oligosaccharides
agaro-oligosaccharides orthogonal matrix HPLC
2009/3/16
Agaro-oligosaccharides were hydrolytically obtained from agar using hydrochloric acid, citric acid, and cationic exchange resin (solid acid). The FT-IR and NMR data showed that the hydrolysate has the...
Influence of Type of Substrate and Enzyme Concentration on Formation of Galacto-oligosaccharides
galacto-oligosaccharides β-galactosidase permeate whey lactose
2014/3/10
Different substrates and different concentrations of enzyme (Maxilact LX 5000) for galacto-oligosaccharides synthesis were tested. Lactose in phosphate buffer (138 mmol/l), ultrafiltration permeate (1...
Production of Oligosaccharides as Promising New Food Additive Generation
oligosaccharides prebiotics food preservative
2009/3/9
Recent research in the area of carbohydrate food ingredients has shown the efficiency of oligosaccharides when they are used as prebiotics or biopreservatives. Considering the former, they have variou...
mmobilization of β-Galactosidase in Adsorptive Membranes for the Continuous Production of Galacto-Oligosaccharides from Lactose
Immobilization β-galactosidase galacto-oligosaccharides
2009/1/15
A method for immobilization of β-galactosidase from Kluyveromyces lactis on an adsorptive membrane for the continuous synthesis of galacto-oligosaccharides from lactose was carried out. The immobiliza...
Finding of Cyclodextrans and Attempts of their Industrialization for Cariostatic Oligosaccharides
cyclodextran cyclodextran glucanotransferase dental caries inhibitor
2008/4/20
Cyclic isomaltooligosaccharides or cyclodextrans (CIs) are cyclic oligosaccharides of α-1,6 linked glucose residues. CIs are highly water-soluble and were found to strongly inhibit glucansucrase activ...
Accumulation of Cello-oligosaccharides during Bacterial Cellulose Production by Acetobacter xylinum
Acetobacter xylinum cello-oligosaccharides cellulose acetan
2008/4/20
Acetobacter xylinum ATCC23769 produces not only cellulose but also various oligosaccharides during cell growth. These oligosaccharides accumulated and increased gradually up to about half the amount o...
Investigations of a Useful α-Glycosidase for the Enzymatic Synthesis of Rare Sugar Oligosaccharides
