In recent years, microbial breeding is a research hot spot. Mutation breeding is an important way in modern food industry and fermentation industry. On the basis of understanding the traditional physical mutation breeding, a series of new mutation methods, such as ion implantation, microwave, laser, ultra-high pressure, space and other new mutation factors and the emergence of mutation agents, have added many bright spots to the physical mutation technology, and further improved the efficiency and success of mutation breeding. |
