Web4 de out. de 2024 · ONPG: β-galactosidase Test. O-Nitrophenyl-β-D-galactopyranoside (ONPG) is structurally similar to lactose (i.e. ONPG is an analog of lactose), except that orthonitrophenyl has been substituted for glucose. On hydrolysis, through the action of the enzyme β-galactosidase, ONPG cleaves into two residues, galactose and o-nitrophenol. WebONPG Disks are used to detect the presence of β-galactosidase, an enzyme found in lactose-fermenting organisms. Lactose utilization depends upon two enzymes: β …
