The reporter learned yesterday from Henan Coal Chemical Group that the research institute of the group cooperated with the Key Laboratory of Ion Beam Bioengineering of Henan Province, Zhengzhou University, and started the research on the production of high-yield strains of methanol protein by ion implantation mutagenesis and the research of its production process to promote the enterprise's coal chemical industry. Industrial transformation and upgrading, extending the methanol downstream industrial chain. The partners will use this research as a breakthrough point to develop the technology for the fermentation of methanol protein and the separation and preparation of products with independent intellectual property rights, and is expected to make breakthroughs in the first half of next year.
The project applies the ion implantation mutagenesis technology pioneered in China to improve the strains of methanol protein production, and provides a new way to increase the strain tolerance and conversion efficiency of high concentration methanol. According to reports, compared with conventional mutagenesis methods such as ultraviolet mutagenesis, ion implantation mutagenesis technology can provide more mutagenic conditions, so that methanol proteins with high methanol conversion rate, short fermentation period, and good genetic stability can be screened out. Production strains.
Experts from the Institute of Feed Research of the Chinese Academy of Agricultural Sciences believe that under the current background of excess domestic methanol production capacity, the development of methanol protein can open up a huge potential market for methanol. He analyzed that the gap in the supply of protein for feed in China reached 38 million tons last year. If 10% of it is replaced by methanol, it can consume about 8 million tons of methanol. Up to now, methanol protein has been used abroad for more than 20 years, and it has been proved to be a safe animal feed additive, but at present there is no mature production technology in China. In order to break the monopoly of this technology abroad, the production of methanol protein technology has become a hot spot in domestic research and development.
It is understood that methanol protein is a single-cell protein produced from methanol, and its production technology is very high. Studies have shown that the addition of phosphate, **, etc. nutrients in methanol into the fermentation broth, and then under the appropriate pH and temperature conditions, implantation of methanol protein strains for fermentation, can produce methanol single cell protein, but suitable The cultivation and screening of methanol protein strains is a technical problem that has plagued the production of methanol protein for many years.
