Ventilating/Stirring Culture Tank
First Claim
1. A ventilating/stirring culture tank comprising a longitudinal tubular container that is capable of freely containing culture fluid, within which a rotation shaft that is supported coaxially with the axis of the container, a stirring impeller that is attached to the rotation shaft in order to stir the culture fluid, and an air feed pipe for feeding air into the container, are provided, and wherein an opening for introducing culture medium material and fungal cells is provided in an upper part of the container,wherein a ratio (HT/D) of height (HT) to inner diameter (D) of a cylindrical portion of the container is greater than 3.8, and a baffle plate for causing turbulence within the culture fluid that is being stirred is attached to an inner side of a peripheral wall of the container.
