Abstract

This invention is a magnetically coupled microorganism culture apparatus used in the expansion culture of microorganisms, especially in the expansion culture conducted for test tube microorganisms. In one example, the culture apparatus is powered by a micro motor, rotation of the micro motor is transferred to the air impeller by virtue of a magnetically coupled device, causing the air impeller to rotate at a high speed. Under the effect of centrifugal force, the air in the air impeller is sprayed into the culture medium liquid in the container for the growth of microorganisms. This invention is substantially different from the shaker being used today, thus achieving the purpose of reducing cost and saving energy.
