Abstract
Three-stage multiflow cultivation of the yeast Pichia pinus, with the flow rates of 0.27, 0.6 and 1.2 hr-1, respectively, in the first, second and third fermenters, resulted in autoselection and the parent strain was substituted by a selective one in the third fermenter. The selective strain differed from the parent one by the size of cells, had a higher specific growth rate, and contained more protein. These properties of the selective strain were preserved in the course of one-stage cultivation.
