Genetic engineering fermentation device and fermentation method

The invention discloses a genetic engineering fermentation device and a fermentation method. The genetic engineering fermentation device comprises a fermentation structure, a liquid storage structure and a gas guide pipeline, wherein a liquid filtering structure is arranged in the fermentation structure; the liquid storage structure comprises a first liquid storage chamber and a second liquid storage chamber, the first liquid storage chamber is communicated with a first liquid guide pipeline, and the second liquid storage chamber is communicated with a second liquid guide pipeline. According to the invention, the gas guide pipeline is communicated with the fermentation structure and the liquid storage structure, and steam is introduced to sterilize the fermentation structure and the liquid storage structure, so that the fermentation environment of strains is ensured; the second liquid guide pipeline communicated with the second liquid storage chamber and the fermentation structure is used for providing an ind
