Editor's note: On May 26, 2017, on the occasion of the 60th anniversary of the establishment of the Chinese Academy of Agricultural Sciences, General Secretary Xi Jinping specially sent a congratulatory letter, giving important instructions on "three aspects" and "two first-rate". In the past three years, the Oil Research Institute has conscientiously implemented the spirit of the important instructions of General Secretary Jinping, abided by the mission of the National Agricultural Research Team, took rural revitalization as the overall focus, and accelerated personnel training, technological innovation, achievement transformation, international cooperation, and system and mechanism construction, and achieved good results. Achievement. In order to thoroughly implement the spirit of the congratulatory letter from General Secretary Xi Jinping, accelerate the construction of the "three-oriented" and "two first-class" institutes, and promote the high-quality development of the oil industry, rural revitalization, and the implementation of the healthy China strategy, some scientific and technological achievements, scientific research progress and development achievements are now Be displayed.

　　In view of the long-term research lag in green and high-value utilization technology of oilseed meal, low bioconversion efficiency of meal meal, single meal conversion product and low added value, the oil quality chemistry and processing and utilization team of the oil plant has worked together for many years to research and establish The bio-conversion technology of meal fermentation and enzyme coupling breaks through the key bottleneck of high-value bio-conversion of oil-seed meal, creates a series of high-value products, and opens up a new way for the diversified value-added processing of oil meal resources in my country.

　　The team obtained a series of excellent microbial strains with independent intellectual property rights, biosafety, high-efficiency conversion of cakes and high-yield target substances through coupled ion beam biological mutagenesis and high-throughput targeted screening technology of strains; combined with metabonomics and Exhaust gas analysis technology establishes a dynamic model of culture environment-cell metabolism-process control to achieve dynamic regulation of fermentation bacterial biomass and target production.Compared with the current fermentation production technology, based on the high-efficiency fermentation process using oilseed meal as a new nitrogen source, the fermentation biomass and DHA yield of Schizochytrium were increased by 34.7 times and 17.1 times, respectively, and the fermentation biomass and β of B. trispora were increased. -Carotene production increased by 1.6 times and 5.9 times, respectively. The yield of iturin A produced by Bacillus fermentation was 2.4 times higher than the level reported at home and abroad.This achievement has been successfully applied in many enterprises in Hubei, Zhejiang, Jiangsu, Shandong, etc., and has achieved significant social and economic benefits. It has provided strong technical support for the high-quality and optimal use of oil and sustainable development, enterprise efficiency and farmers' income.
