Culture Devices for Microbiological Testing

Abstract

The invention discloses a culture apparatus for microbiological detection. The culture apparatus comprises a base, a supporter, a crystal oscillator, conductive wires and a top cover. The upper surface of the base is sunken to form a cavity; the supporter is accommodated in the cavity; and the upper surface of the supporter is provided with a circular groove. The crystal oscillator consists of a holder and a quartz oscillator; the holder is of a circular structure, the quartz oscillator is embedded in the holder, both ends of the holder are provided with conductor limit structures, foil-type exciting electrodes are uniformly arranged on the front and back sides of the quartz oscillator respectively, and the joint between each exciting electrode and an external circuit is designed into a disc-shaped structure. The conductive wires include conductors and disc-like clamp structures connected to tail ends of the conductors; the disc-like clamp structures are clamped to the disc-shaped structures to form electrical connection; and the conductors penetrate the conductor limit structures. The top cover seals the base and is provided with connectors for feeding and discharging of culture solution / sample solution. The culture apparatus for microbiological detection has the advantages of shortening culture cycle and improving detection accuracy.

Description

technical field [0001] The invention relates to the technical field of microorganism detection, in particular to a microorganism cultivation device capable of shortening cultivation time and improving detection accuracy. Background technique [0002] With the development of the economy and the continuous improvement of people's living standards, the awareness of food safety is also constantly improving. In the past, as a method for judging whether spoilage bacteria are contained in food or beverage, there are machine-based methods such as immunoassay, ELISA, gas chromatography mass spectrometry, liquid chromatography mass spectrometry, etc., but the pretreatment of the measurement It is complicated, and the accuracy of judgment cannot be said to be sufficient. Thus, it generally takes a long time to cultivate spoilage bacteria. [0003] Use techniques that include labeling the microorganisms to highlight the contrast between the light emitted by the microorganisms and the ...

Problems solved by technology

The disadvantage of these methods is that relatively long incubation periods are required in order for the colonies formed on the agar medium to be detectable with the naked eye

The disadvantage of these methods is that several kinds of DNA strands are required, that is, several kinds of microorganisms, generally at least dozens of microorganisms, which are not as sensitive as growth-based methods.

[0005] The method of cultivating the microorganisms to be detected on agar medium is relatively common, but its disadvantage is that the cultivation time is too long. How to shorten the cultivation time and improve the efficiency has become a bottleneck that needs to be broken through
