Liquid submerged culture device for microorganisms

Abstract

The invention belongs to the technical field of microorganism culture, and particularly relates to a liquid submerged culture device for microorganisms, which comprises a bacterial culture tank body, four support legs are fixedly mounted on the lower surface of the bacterial culture tank body, and a top end cover is fixedly mounted at the top end of the bacterial culture tank body. The oxygen supply amount in a culture solution in the bacterial culture tank body can be effectively adjusted by utilizing gas floating and the rotating effect of the stirring barrel, and on one hand, a proper amount of oxygen needed by growth and development of microorganisms is kept; on the other hand, the culture solution is stirred and vertically mixed by utilizing the inflow of sterile air, nutrient substances are uniformly distributed to promote rapid growth, biomass is increased, and a large amount of metabolites are generated, so that the problem that when an existing fermentation tank is used for culturing aerobic and anaerobic microorganisms, due to the fact that the quantity of the culture tank bodies is large and the depth is high, the culture time is short is effectively solved. The problem that aerobic and anaerobic microorganisms in the tank body do not have uniform oxygen supply requirements and the microorganisms grow slowly is solved.

Description

technical field [0001] The invention belongs to the technical field of microorganism cultivation, and in particular relates to a liquid submerged cultivation device for microorganisms. Background technique [0002] The medium can be used to supply microorganisms, plants or animals (or tissues) for growth and reproduction. Different nutrients required by different microorganisms generally require the preparation of special medium, which generally contain carbohydrates, nitrogenous substances, inorganic salts (including Trace elements), vitamins and water, etc. The culture medium is not only the basic substance to provide cell nutrition and promote cell proliferation, but also the living environment for cell growth and reproduction. There are many types of culture medium, which can be divided into natural and Medium, synthetic medium, and semi-synthetic medium; according to the physical state, it can be divided into solid medium, liquid medium, and semi-solid medium.

AI Technical Summary

Problems solved by technology

[0003] In order to obtain a large amount of fermentation products, a large-capacity fermenter liquid culture is used for the purpose of aerobic bacteria, and the anoxic condition of the deep culture medium in the fermenter is maintained. It can grow rapidly in an aerobic environment, and it is suitable for both aerobic and aerobic bacteria. aerobic microorganisms, then start the aeration and stirring device of the fermenter, and pass the air compressed in the air storage tank into the fermenter after filtering and sterilizing. , due to the large volume and high depth of the culture tank, the aerobic and anaerobic microorganisms in the tank do not get a uniform oxygen supply demand, resulting in slow growth of microorganisms
