| titleOfInvention | A kind of preparation method of mutant strain with high production of vitamin B12 |
| abstract | The invention belongs to the technical field of strain preparation in bioengineering, and relates to a mutant strain with high vitamin B12 component production and industrial fermentation technology, in particular to a production and cultivation method for a mutant strain with high vitamin B output; The specific mutagenesis process steps include: preparation of starting bacteria suspension, mutagenesis, colony counting, strain primary screening and strain re-screening; after mutagenizing the original strain, it is subjected to normal temperature and normal pressure plasma (ARTP) mutagenesis again. The technology mutates a strain with typical mutagenic characteristics, and finally obtains a strain with stable genetic properties and high fermentation level; the involved mutant strain TP-121 realizes industrial fermentation to produce vitamin B12 The method includes the following steps: Bottle preparation, seed tank culture and fermentation tank culture; the process principle is reliable, the operation steps are simple, the technical conditions are mature, the strains are high-quality, the vitamin yield is high, and the application environment is friendly. |
