Xu Guohua's personal experience.

Comrade Xu Guohua has been engaged in the production practice, technological innovation and application research of new technologies and achievements of biological fermentation and related technologies for many years. He has presided over and participated in 6 national projects, 3 provincial projects and more than 50 municipal and enterprise self-reliance projects; 3. Participate in the formulation of national/industry standards; 37 patents were applied, including 13; Participate in the preparation of 4 monographs; Published more than 20 papers. Eight scientific research achievements, such as glutamic acid green manufacturing technology, which he presided over have reached the international advanced level through the appraisal of provincial achievements, and won two second prizes for provincial scientific and technological progress, three third prizes for provincial technological invention 1 kloc-0/,three third prizes for provincial scientific and technological progress and six municipal scientific and technological awards. The scientific research team led by Comrade Xu Guohua has successfully developed the new technology of dry granulation of bio-fermented fertilizer, reformed and implemented the new technology of starch precipitation, designed and used the largest aerobic fermentor in the international amino acid fermentation industry, popularized and implemented the crystallization process, developed the green manufacturing technology of glutamic acid, and developed and transformed the new technology of extracting small amino acids by full membrane method. At the same time, the development benefits of new products such as branched-chain amino acids, threonine, polyglutamic acid and new xanthan gum are remarkable. These achievements not only improve the core technical level and international market competitiveness of enterprises, but also create remarkable social, environmental and economic benefits for enterprises. At present, a number of projects have been promoted to the whole industry by China Fermentation Industry Association, especially in the innovative application of clean production, recycling efficiency, energy saving and emission reduction, which has made outstanding contributions to the technological progress of China fermentation industry. He has won many scientific and technological progress awards, among which, the research and development and application of key technologies and equipment for green manufacturing of glutamic acid (the international leading level) won the second prize of scientific and technological progress in Shandong Province in 2009; Research on key technologies of two-stage extraction of glutamic acid and reuse of reclaimed water (international advanced level), won the second prize of scientific and technological progress in Shandong Province in 2008; "Study on comprehensive treatment of flue gas from spraying granulation of glutamic acid fermentation waste liquid" (international advanced level) won the third prize of technical invention in Shandong Province in 2008; The research and development (international advanced level) of the new technology of extracting amino acids by full membrane method won the third prize of Shandong Province for scientific and technological progress in 2009; The research and application of the new technology of starch gluten sedimentation (international advanced level) won the second prize of Linyi technical invention in 2008; The research on the production of sodium glutamate from β -glutamic acid and its key technology (international advanced level) won the second prize of scientific and technological progress in Linyi City in 2008; The research and development of key technologies of new monosodium glutamate production process (international advanced level) won the second prize of scientific and technological progress in Linyi City in 2009; New technology for efficient production of polyglutamic acid functional materials by microorganisms (international advanced level).
