Continuous fermentation device for slime producing bacteria

Abstract

The invention discloses a continuous fermentation device for slime producing bacteria. The continuous fermentation device comprises a hanging bottle, an upper cap, a lower cap and a collection bottle, openings are formed in the upper portion and the lower portion of the hanging bottle, the lower cap is provided with a conical top, the bacteria and a liquid culture medium are separated by the aid of bottleneck barrier action and properties of gel in a solid culture medium, continuous stable nutrient substances are provided for the bacteria by the aid of gravity action, bacterial agents are automatically collected by the aid of slime producing characteristics of the bacteria, the conical bare solid culture medium is manufactured by the aid of the lower cap, so that bacterial strains are conveniently inoculated, the bacterial agents are conveniently collected, glass and resin materials are selected, high-pressure steam sterilization can be achieved, combination of shapes is designed, and sterilization and sterile operations are facilitated. The continuous fermentation device can be used for fermentation production of slime producing bacteria, continuous fermentation production of the bacterial agents is achieved, the culture media keeps fresh, and fermentation processes of the slime producing bacteria are saved, continuous and facilitated.

Description

technical field [0001] The invention relates to the field of microbial equipment, in particular to a continuous fermentation device for slime-producing bacteria. Background technique [0002] Media such as agar gel allow the passage of nutrients in the culture medium while blocking the passage of bacterial cells. The existing bacterial fermentation technology adopts the method of mixing bacteria and culture medium liquid. Due to the influence of factors such as bacteria’s self-secretion inhibitors, it enters the decline period after a period of logarithmic growth phase. Nutrients and bacteria’s self-inhibiting substances are mixed together, resulting in no The waste of the remaining nutrients is avoided, and the growth rate of bacteria is also inhibited. Some bacteria produce slime, such as rhizobia that can symbiotically fix nitrogen with legumes. The symbiosis between rhizobia and legumes can improve soil fertility, reduce the use of chemical fertilizers, improve food qua...
