Abstract/OtherAbstract:
We describe the synthesis of a new substrate for the detection of beta-galactosidase and evaluate its performance in comparison with 5-bromo-4-chloro-3-indolyl-beta-D-galactopyranoside (X-Gal) and cyclohexenoesculetinbeta-D-galactoside (CHE-Gal). Of 206 Enterobacteriaceae strains able to hydrolyze X-Gal, 194 (94.2%) hydrolyzed CHE-Gal and 192 (93.2%) hydrolyzed p-naphtholbenzein-beta-D-galactoside (PNB-Gal). We conclude that PNB-Gal is an effective substrate for the detection of beta-galactosidase.
