Preservation device of walnut endophytic bacteria HB1310 for producing oil by fermenting cotton stalk and hydrolyzing sugar liquor

Abstract

The invention discloses a preservation device of walnut endophytic bacteria HB1310 for producing oil by fermenting cotton stalk and hydrolyzing sugar liquor. The preservation device comprises a shell mechanism, a combination mechanism, a freezing mechanism, a connecting mechanism, a sealing mechanism and a storage mechanism. The combined mechanism is arranged on the shell mechanism, the freezing mechanism is arranged in the shell mechanism through the connecting mechanism, the sealing mechanism is fixedly installed on the upper surface of the interior of the shell mechanism, the sealing mechanism is located over the freezing mechanism, and the storage mechanism is placed in the freezing mechanism. According to the device, by arranging the combination mechanism, a plurality of devices can be combined, so that different strains can be conveniently classified and placed, and a large amount of space can be saved; through the arrangement of the box door and the connecting mechanism, a worker can put in and take out strains more conveniently; and by arranging the sealing mechanism, a sealing effect can be achieved on the freezing mechanism, and the cleanness of the interior of the freezing box can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of microorganism preservation devices. Specifically, it is a storage device for walnut endophytic bacteria HB1310 produced by hydrolyzing sugar liquid from fermented cotton stalks. Background technique [0002] In genetic engineering, it is necessary to store the constructed strains at low or even ultra-low temperatures, place the cultivated strains in a test tube, and then store them in a low-temperature environment so that they are in a dormant state; while in existing applications Most of the low-temperature environments used to store strains are refrigerators, which are relatively large in size. When using this method to store the test tubes containing the strains, the test tubes cannot be fixed, and the strains should be taken out or filled. When entering, you need to hold the test tube or need a separate test tube rack, which is very inconvenient. Contents of the invention [0003] For this reason,...

[0002]In genetic engineering, it is necessary to store the constructed strains at low or even ultra-low temperature, place the cultivated strains in a test tube, and then store them at low temperature environment, so that it is in a dormant state; and the low-temperature environment used to store strains in existing applications is mostly refrigerators, which are relatively large in size. When using this method to preserve test tubes containing strains, The test tube cannot be fixed, and it is very inconvenient to hold the test tube or need a separate test tube rack when taking out or loading the seed solution
