| titleOfInvention | Strain preservation method applied to fermentation massive production |
| abstract | The invention discloses a strain preservation method which is characterized by comprising the following steps: 1, eluting a sterilization eluting solution in a grown-up strain on a solid slant culture medium to prepare a bacterium suspension; 2, filtering the bacterium suspension to remove the culture medium; 3, subpackaging the filtered bacterium suspension by using a cryovial; and 4, placing the strain loaded with the subpackaged bacterium suspension in an environment with a temperature of minus 78 DEG C to minus 82 DEG C for ultralow temperature preservation. By adopting the technical scheme, the strain preservation method has the remarkable advantages that the frequent passage of the strain is not needed, the strain characters are ensured and do not easily mutate; the preservation space can be reduced, the safe and reliable environment for preserving the strain is ensured; and living contaminants are reduced or avoided. The production efficiency and quality are favorably improved. |
