Microbial flora continuous screening device

Abstract

The invention discloses a microbial flora continuous screening device which comprises a culture medium storer, a feed liquid reaction chamber and a microbial flora collecting chamber. The bottom of the culture medium storer is connected to the feed liquid reaction chamber through a first hose, the bottom of the feed liquid reaction chamber is connected to the microbial flora collecting chamber through a second hose, and a drain hose is arranged at the bottom of the microbial flora collecting chamber. Based on a microbial continuo's culture theory, microbial screening is located in a dynamic state, nutritional substances required by microorganisms can be immediately and continuously supplemented, and part of harmful metabolites can be immediately discharged to promote growth and reproduction of microorganisms; by taking nutritional substances such as the culture medium as a food of microorganisms, related microbial flora is promoted to form a food chain, and finally, target degrading flora is quickly screened, so that the demand on screening the microbial mixed flora in industrial scaled production is met.

Description

technical field [0001] The invention belongs to the technical field of biochemical equipment, and in particular relates to a continuous screening device for microbial flora, which is specifically used for screening microbial flora for transforming low-rank coals such as lignite and peat, and biomass. Background technique [0002] Fermentation tanks are widely used in the fermentation of microbial strains, and have the advantages of fast fermentation, cleanliness and large-scale production. The traditional microbial fermentation process is the result of the participation of multiple microorganisms. In long-term experiments and production practices, people have gradually found that a single microorganism often only participates in one or several steps in the biochemical metabolism process, so it can only be inefficient or completely ineffective. The metabolic and catalytic process of fermentation raw materials can be realized, so humans began to re-examine the unique advantage...
