Screening and identification of β-galactosidase-producing microorganism and enzymatic synthesis of galacto-oligosaccharides using its transgalactosylation;

Recent progress on galacto-oligosaccharides synthesis by microbial β-galactosidase——A review;

Enterobacter agglomerans B1 producing β-galactosidase with transglycosylation activity:screening,identification,fermentation conditions,and galacto-oligosaccharides synthesis;

Production of low-lactose milk containing galactooligosaccharides was studied withβ-Galactosidase by transgalactosylation activity from Enterobacter sp.

The molecular structure,origin,physiological functions and the states of application in infant food industry of both fructooligosaccharides and galactooligosaccharides are reviewed.

The conditions for transgalactosylation activity were optimized,and the large yield of galactooligosaccharides with various kind of oligosaccharides was obtained by using 20% lactose as a substrate at pH 5.

Study the effect of galactooligosaccharide on the function of smoothing intestine and defecating feces excretion;

The paper illustrates briefly the synthesis prmciple and production technology of producing functional Qligasaccharides－ Lactulose,galactooligosaccharide and lactosucrose,with lactose.

Isolation of galacto-oligosaccharide by filtration

The effects of time, initial lactose concentration, temperatur e, enzyme amount and pH on the synthesis of galacto-oligosaccharide from lactos e using β-galactosidase were investigated.

Oligo-galactose etc.
