Abstract: MYCELIA HAVING STRONG A-GALACTOSIDASE ACTIVITY AND VERY WEAK INVERTASE ACTIVITY ARE OBTAINED BY CULTURING A MOLD BELONGING TO THE GENUS ABSIDIA IN A CULTURE MEDIUM INCORPORATING THEREIN AT LEAST ONE MEMBER SELECTED FROM THE GROUP CONSISTING OF LACTOSE, MELIBIOSE, RAFFINOSE AND GALACTOSE. WHEN BEET MOLASSES IS TREATED WITH THE SAID MYCELIA, RAFFINOSE CONTAINED IN THE MOLASSES IS DECOMPOSED INTO SUCROSE AND GALACTOSE. THUS, THE YIELD OF SUCROSE CAN BE INCREASED.

Abstract: A HIGHER FATTY ACID, A HIGHER ALCOHOL, A HIGHER ALDEHYDE OR A FUNCTIONAL DERIVATIVE THEREOF HAVING 12 OR MORE CARBON ATOMS IS INCORPORATED AS AN AGENT FOR ACCELERATING THE FORMATION OF A-GALACTOSIDASE INTO A BASIC CULTURES MEDIUM CONTAINING CARBON SOURCES, NITROGEN SOURCES AND INORGANIC SALTS. WHEN AN A-GALACTOSIDASE PRODUCING MOLD IS CULTURED IN THE CULTURE MEDIUM THUS PREPARED, AGALACTOSIDASE IS PRODUCED IN HIGH YIELDS IN A SHORT PERIOD OF CULTURING TIME.
