The invention discloses bradyrhizobium japonicum vitrified cryopreservation liquid and a method for vitrified cryopreservation of bradyrhizobium japonicum and relates to microorganism vitrified cryopreservation liquid and a method for vitrified cryopreservation of microorganisms. The bradyrhizobium japonicum vitrified cryopreservation liquid contains ethanediol and is simple in compound composition. The bradyrhizobium japonicum vitrified cryopreservation liquid is composed of glycerinum, ethanediol, DMSO and distilled water. According to the method for vitrified cryopreservation of the bradyrhizobium japonicum, bradyrhizobium japonicum liquid is added into the bradyrhizobium japonicum vitrified cryopreservation liquid, and then the bradyrhizobium japonicum vitrified cryopreservation liquid is put into liquid nitrogen for fast vitrified cryopreservation. The bradyrhizobium japonicum vitrified cryopreservation liquid and the method for vitrified cryopreservation of the bradyrhizobium japonicum are used in the field of microorganism preservation.
Description
technical field [0001] The invention relates to a microorganism vitrification freezing storage solution and a method for vitrification freezing storage of microorganisms. Background technique [0002] Rhizobium is a class of Gram-negative rod-shaped bacteria that live in soil. Under suitable conditions, Rhizobium can infect legumes and perform symbiotic nodulation and nitrogen fixation with them. It is estimated that the nitrogen fixed by rhizobia accounts for about 65% of the total biological nitrogen fixation, which plays an extremely important role in agricultural production. Strain resources are an important part of my country's rich natural resource treasure house. With the continuous development of biological technology, the utilization of germplasm resources plays an increasingly important role in the research of life sciences. higher and higher requirements. In order to make the wild-type strains isolated from nature and the excellent strains obtained by artificial ...
