Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to the field of machinery, in particular to a biological enzyme culture stirring device.
[ background of the utility model ]
The existing biological enzymes are usually produced by microbial fermentation. The method comprises the steps of culturing a microorganism introduced with a biological enzyme gene, starting to produce the biological enzyme when the microorganism grows to a preset period, extracting a culture medium after the microorganism is cultured to a certain degree, and filtering and purifying to obtain the corresponding biological enzyme. However, during the fermentation of the microorganisms, the culture medium cannot stand still, otherwise the microorganisms gradually settle and accumulate, and the growth of the microorganisms is influenced. The existing method is generally provided with stirring blades. However, when the stirring blade stirs, a large mechanical shear is generated, resulting in death of the cultured microorganisms. Therefore, a new stirring method is required.
