Abstract

PURPOSE: To obtain a novel β-galactosidase having improved acid resistance, heat resistance, and medicinal and pharmaceutical properties, by cultivating a strain belonging to "Paecilomyces varioti".
CONSTITUTION: A β-galactosidase producing microorganism belonging to "Paecilomyses varioti", e.g., "Paecilomyces varioti" AHU 9433, AHU 9417, AHU 9254, etc. is inoculated into a nutrient medium and cultivated under aerobic conditions, to give a culture. A substrate containing β-D-galactoside bond, e.g., o-nitrophenyl- β-D-galactopyranoside, lactose, etc. obtained from the culture is subjected to hydrolysis so that the β-D-galactoside bond is hydrolyzed, to collect a novel β-D- galactosidase having the fittest pH3.0W4.5 and the fittest temperature 60W68°C.
