Small aerobic bacteria culture device and aerobic bacteria culture method

Abstract

The invention relates to a small aerobic bacteria culture device and an aerobic bacteria culture method. The small aerobic bacteria culture device comprises a heat preservation water tank, a liquid storage bottle, a breather pipe, an exhaust pipe, a liquid injection pipe, an injector, a temperature controller, a temperature measuring probe and a heating probe, the liquid storage bottle is placed in the heat preservation water tank, a bottle plug is arranged in the opening of the liquid storage bottle, and the breather pipe, the exhaust pipe and the liquid injection pipe sequentially penetratethrough the bottle plug to extend into the liquid storage bottle; the breather pipe extends into the bottom of the liquid storage bottle; the exhaust pipe extends to the position above the liquid level of liquid in the liquid storage bottle; the liquid injection pipe extends into the position below the liquid level of the liquid in the liquid storage bottle; and the temperature controller is arranged on one side of the heat preservation water tank, the temperature controller is connected with the temperature measuring probe and the heating probe, and the temperature measuring probe and the heating probe penetrate through the side wall of the heat preservation water tank into the heat preservation water tank. The advantages that the cost is low, simpleness, convenience and practicability are achieved, and the culture environment can be controlled are achieved. According to the small aerobic bacteria culture device and the aerobic bacteria culture method, normal growth of biochemical bacteria is guaranteed through a nutrient solution and an activating agent, the acclimation time of aerobic bacteria is shortened, and the biochemical processing efficiency is improved.

Description

technical field [0001] The application belongs to the technical field of microorganism cultivation, and in particular relates to a small aerobic bacteria cultivation device and an aerobic bacteria cultivation method. Background technique [0002] The cultivation of microorganisms requires four essential basic conditions: culture medium (ie, nutrients), temperature, gas environment, and pH. Aerobic bacteria are a type of microorganisms that have a relatively complete respiratory enzyme system, require molecular oxygen as a hydrogen acceptor, and can only grow and reproduce under aerobic conditions. With the continuous development of biotechnology, the demand for pure culture of aerobic bacteria in the field of microbial fermentation is increasing. [0003] At present, the laboratory culture of aerobic bacteria is a common, simple and mature technology, such as liquid and solid culture; test tube, plate, eggplant-shaped bottle culture, etc., but the process of mass production...

AI Technical Summary

Problems solved by technology

In the field of pure culture fermentation of large quantities of aerobic bacteria or facultative aerobic bacteria, the traditional fermenter liquid aeration culture method is mostly used. This method generally has the disadvantages of easy pollution in the production process, low production efficiency, difficulty in concentrating the bacterial liquid, and sewage discharge. Bottlenecks such as many and high production costs
