Abstract
PURPOSE: To improve the production of the titled substance, by cultivating a yeast having the ability to produce the titled substance by the sprinkling (spreading) or continuous culture method aerobically while controlling the specific growth rate at a specified value.
CONSTITUTION: A yeast of the genus Saccharomyces, Pichia, etc. having the ability to produce ergosterol is cultivated in a culture medium containing a carbon source, e.g. glucose, sucrose or an alcohol, a nitrogen source, phosphorus or potassium. The cultivation is carried out by the sprinkling (spreading) or continuous culture method aerobically, and the specific growth rate (u) is controlled at 0.05W1.15hr-1. The controlling method is as follows: (1) The feed rate of the carbon source is controlled. (2) The pH is controlled. (3) The cultivation temperature is controlled. According to the aerobic cultivation method, the production of the ergosterol can be improved.
