Laboratory anaerobic fermentation equipment and anaerobic fermentation method

Abstract

The invention discloses laboratory anaerobic fermentation equipment and an anaerobic fermentation method.The laboratory anaerobic fermentation equipment comprises a bottle body, a rubber plug is arranged at an opening of the bottle body, the rubber plug can seal the bottle body so as to guarantee the sealed oxygen-free environment in the bottle body, and a sampling pipe for sampling detection is arranged on the rubber plug; the rubber plug is provided with an alkali adding pipe and an air outlet pipe ; the alkali adding pipe is used for adjusting the pH value and adding alkali liquor, the air outlet pipe is used for adjusting the air pressure in the bottle to ensure that the bottle body is not damaged, the anaerobic fermentation process can be completed, the method is easy to operate, the overall sealing effect is good, correct experimental data can be obtained, and the problems of high cost and much waste caused by experiments in the prior art are solved. Different from the problem that the existing simple fermentation device cannot be randomly sampled, the laboratory anaerobic fermentation equipment is extremely high in flexibility and is very suitable for reducing the experiment cost in a laboratory.

Description

technical field [0001] The invention specifically relates to a laboratory anaerobic fermentation equipment and an anaerobic fermentation method. Background technique [0002] Laboratory anaerobic fermentation mainly relies on 5L-20L fermenter for anaerobic fermentation test. The fermenter equipment is expensive, the operation is complicated, and the test cost is high. It is not suitable for simultaneous testing of multiple formulas in the screening medium test. [0003] The anaerobic fermentation device disclosed in existing patents, such as a kind of anaerobic fermentation device whose patent number is CN209210795U, a kind of graphite anaerobic fermentation device whose patent number is CN207072939U and a kind of anaerobic fermentation device whose patent number is CN202786227U, etc. There are more or less defects. There are problems that the anaerobic fermentation device cannot take samples and count, detect the pH value, and adjust the pH of the fermentation broth during...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned problem of lack of suitable equipment for anaerobic fermentation experiments in laboratories, the present invention provides a laboratory anaerobic fermentation equipment, which requires simple equipment and high cost performance, and can solve the problem of sampling at different time points during the test process. , detect the pH value, adjust the pH, maintain the anaerobic environment of fermentation, etc.; and can not only carry out the anaerobic fermentation test of aerobic bacteria, but also can carry out anaerobic fermentation without gas production, and at the same time discloses a laboratory Anaerobic fermentation method, dedicated to this equipment for anaerobic fermentation experiments
