Abstract: In the fermentation process according to the invention with continuous mass cultivation of ciliates (protozoa), the ciliate cells are cultivated in a complex axenic medium—free from living feed or prey organisms—and the biomass containing the desired biogenous valuable substances is obtained by continuous (permanent) cell extraction.
Abstract: The invention relates to a method for culturing ciliates comprising the steps of placing ciliates and medium therefor in a culture flask; providing said culture flask with a stirrer having a magnetic core, wherein said stirrer is suspended in the top part of the culture flask such that the stirrer does not touch the flask bottom, and wherein the motion of said stirrer is driven by means of a magnetic field; and stirring said ciliates in said culture medium.
