Abstract

PURPOSE: A part of culture mixture is taken out of the cultivation tank, separated into the yeast and the supernatant, the yeast is subjected to disinfection treatment, then reactivation treatment, the supernatant also is treated in the same way, and both of them are made to turn back to the tank, thus effecting the cultivation without deactivation and contamination by other microorganisms.
CONSTITUTION: A part of culture mixture is introduced from line 3 into separator II. The yeast separated is introduced through line 4 into disinfector III, where the yeast is treated chemically, then the treated yeast is sent to the reactivator, where the yeast deactivated by the disinfection treatment is reactivated. For example, the yeast is reactivated, when it is treated with an acid, by adding small amounts of a major carbon sources and nourishing sourcs and aerating at a pH of 4W6 for about 60min. The reactivated yeast is made to turn back to the fermentator I for cultivation. Meanwhile, the supernatant separated in separator II is introduced into disinfector V, sterilized or made germ-free and then made to return back to the fermentator I.
