β-Galactosidase (β-Gal) as dietary supplement has the ability to alleviate symptoms of lactose intolerance. This study investigated the ability of oligosaccharides to protect β-Gal against heat stress. Four kinds of oligosaccharides including Isomalto-oligosaccharides (IMO), Xylo-oligosaccharides (XOS), Konjac-oligosaccharides (KOS), and Mycose

lacZ gene mutations in the transgenic Muta Mmouse can be detected by two different selection systems. While mutant frequencies recovered by phenyl-beta-D-galactoside (P-gal) selection are comparable with those obtained using 5-bromo-4-chloro-3-indolyl beta-D-galactopyranoside (X-gal) as substrate for beta-galactosidase, there may still
