Zusammenfassung:	PURPOSE:To obtain beta-galactosidase at a low cost, by culturing a beta-galactosidase- producing microbial strain belonging to Penicillium genus in a liquid medium in the presence of a vegetable polysaccharide and a water-insoluble material, thereby remarkably improving the productivity of the enzyme. CONSTITUTION:A beta-galactosidase-producing microbial strain belonging to Penicillium genus is cultured in a liquid medium under aerobic condition, and beta- galactosidase is separated from the cultured product. In the above process, the cultivation is carried out in the presence of a vegetable polysaccharide containing galactose as a part of the constituent components and a water-insoluble material having an average particle diameter of
