Lactic acid bacteria separating, screening and culturing device

Abstract

The invention discloses a lactic acid bacteria separating, screening and culturing device, and relates to the technical field of lactic acid bacteria separating and culturing. The lactic acid bacteriaseparating, screening and culturing device comprises a constant-temperature box, supporting bases are arranged at the bottom of the constant-temperature box, the multiple supporting bases are arranged, a disinfection box is fixedly connected to the top of the constant-temperature box, supporting plates are connected between the inner walls of two sides of the constant-temperature box in a slidingmode, culture dishes are arranged at the tops of the supporting plates, the number of the support plate and the culture dish are multiple, and a first clamping plate and a second clamping plate are correspondingly and fixedly connected between the inner walls, close to the top, of two sides of the disinfection box. According to the device, by arranging the disinfection box, rapid disinfection ofa inoculating loop is realized, the defect that the inoculating loop needs to be disinfected by an alcohol lamp every time the inoculating loop is used during streak separation of lactic acid bacteriaby a plate streak method is avoided, and the inoculating loop is placed in the disinfection box and can be directly taken out for use during use.

Description

technical field [0001] The invention relates to the technical field of separation and cultivation of lactic acid bacteria, in particular to a device for separating, screening and cultivating lactic acid bacteria. Background technique [0002] Lactic acid bacteria is a general term for a class of bacteria that can use fermentable carbohydrates to produce a large amount of lactic acid. This type of bacteria is widely distributed in nature and has rich species diversity. It includes at least 18 genera and more than 200 species in total. Except for a few, Most of them are essential flora in the human body and have important physiological functions, and widely exist in the intestinal tract of the human body.

Problems solved by technology

[0003] At present, before large-scale cultivation of lactic acid bacteria, a small amount of culture testing is usually carried out on the lactic acid bacteria that require a large amount of cultivation, to detect the high quality of lactic acid bacteria and to screen the lactic acid bacteria. Currently, when separating and screening lactic acid bacteria, usually The high-quality lactic acid bacteria are screened and cultivated by the plate streaking method. When streaking the petri dish with an inoculation loop, it usually needs to be sterilized with an alcohol lamp every time it is streaked, which is very troublesome, and it is necessary to wait for inoculation before use. The ring can only be used when it is completely cooled down, so a lactic acid bacteria isolation and screening culture device is introduced to solve the above-mentioned problems
