Recommended by graduate tutor: Min, from Da 'an City, Jilin Province, party member, CPC. In September, 20__, I was admitted to the School of Food Science and Nutritional Engineering of China Agricultural University to pursue my doctorate.
During the doctoral study, the student earnestly studied the spirit of "Theory of Three Represents" and "18th National Congress" and actively participated in various activities of Party organizations, schools and laboratories. Treat people sincerely and enthusiastically, experiment carefully, work hard and work hard. He has completed all the courses required to apply for a doctoral degree, with excellent academic performance, and completed 17 credits, with an average score of 8 1. At home, < Food and Fermentation Industry >: 5 papers published in relevant professional journals.
The project undertaken by Min Weihong is an international cooperation project. Taking early indica rice, which accounts for 80% of the national overstocked rice, as raw material, she explored the production of rice noodles by pure lactic acid bacteria for the first time on the basis of traditional natural fermentation, and studied the mechanism of improving the eating quality of rice noodles by lactic acid bacteria and the mechanism of starch denaturation and gelation of lactic acid bacteria. The fermentation technology of rice flour by lactic acid bacteria was discussed, and the evaluation model and method of starch gel food such as rice flour, vermicelli and rice flour were established. So as to lay a theoretical foundation for producing high-quality rice flour from early indica rice.
In this paper, the improvement effect of lactic acid bacteria fermentation products on the quality of rice noodles was innovatively studied, and the gluten sensory model of starch gel food was established. Study on the technology of rice flour fermented by lactic acid bacteria.
The author of this paper can comprehensively consult domestic and foreign literatures and grasp the trends in this research field. The results of the paper reflect that the author has a solid theoretical foundation, is proficient in advanced experimental skills in microbiology, physical chemistry and food engineering, and has the ability to engage in the above scientific research independently.
I think this doctoral thesis has met the requirements for applying for a doctoral degree. I hereby agree to reply and recommend applying for a doctoral degree.
The second Ding Changhe is a doctoral student in Class 20. I graduated from Beijing Agricultural Engineering University in with a bachelor's degree in food engineering and a master's degree in food science and engineering from Wuxi Institute of Light Industry. He also served as the technical director of Henan Jinxing Brewery, the sixth largest beer group in China, for three years.
While studying at school, Ding Changhe supported the Party's line, principles and policies and actively participated in various activities organized by schools and colleges. In daily research and study, I can be strict with myself, stick to the truth, be brave in exploration, be sincere and enthusiastic, be helpful and unite my classmates.
Ding Changhe paid attention to the study of basic theoretical knowledge and the improvement of experimental skills, and read a large number of books and materials related to research, with a wide range of knowledge. During my study, I worked hard and got excellent grades, with a total score of 17 credits and an average score of 85 points. In the research work, two academic papers were accepted by domestic core journals. Another 1 paper has been accepted by foreign SCI index source magazines and is being revised. The research topic I am engaged in is a sub-project of "Functional Oligosaccharides", a key scientific and technological project of the Tenth Five-Year Plan, and the project number is _ _ _ _. The preliminary research of this project was appraised as a scientific and technological achievement by the Ministry of Education in June, 20 _ _, and won the second prize of Shandong Science and Technology Progress in September, 20 _ _, and Ding Changhe was one of the main finishers of this project.
Ding Changhe's graduation thesis "Study on High Yield and Enzymatic Properties of Streptomyces Xylanase" was completed. On the basis of consulting a large number of domestic and foreign literatures, a Streptomyces tiande with high xylanase production was screened and identified for the first time in China, and the effects of mutation and optimization of enzyme production conditions on Streptomyces tiande's enzyme production were studied. The activity of liquid fermentation enzyme is the highest in China. In this paper, xylanase from Streptomyces tiande was purified, and electrophoretic pure low molecular weight xylanase was obtained. The enzymatic properties of the enzyme were further studied, which laid the foundation for its application. In addition, the enzyme production conditions of Streptomyces fuscus were optimized and the pilot test was carried out. The xylanase activity of Streptomyces olivaceus is the highest at home and abroad.
The research paper is closely combined with the development of national economy, and the experimental scheme is reasonable, the data is accurate and the conclusion is reliable.
The research results have important theoretical significance and practical value, which laid the foundation for the high yield and industrial application of xylanase.
The paper mainly involves microbiology, biophysics, biochemistry, fermentation engineering and other disciplines, which shows that Ding Changhe has mastered profound basic theoretical knowledge and systematic professional knowledge and has the ability to carry out scientific research independently.
There are still some contents in this paper, such as the mechanism of inducing high-yield xylanase by corn cob water-insoluble xylan and the optimization of fermentation conditions for enzyme production in 200-liter pilot fermentor, which can not be perfected due to the limitation of time and conditions.
In a word, I think Ding Changhe's thesis has reached the level of doctoral thesis, and I recommend to participate in the doctoral thesis defense, and I suggest that the doctoral degree be awarded after the defense is passed.
Part III 1
_ _ In the postgraduate study stage, I seriously studied the relevant core courses and laid a solid foundation for scientific research; During the preparation of master's thesis, I actively participated in various teaching and scientific research activities, and during the teaching practice, I carefully read the teaching materials and consulted academic materials, which greatly improved my professional level. At the same time, he also has strong hands-on ability, participated in many topics of his tutor, and greatly improved his theoretical and practical level. I believe that these experiences and accumulation will become valuable wealth on his life path.

_ _ In the postgraduate study stage, pay attention to the study of political theory, care about state affairs, support the party's line, principles and policies, always bear in mind social responsibilities, resolutely resist cult organizations, and take a firm political stand. In the study of specialized courses, I have carefully studied the core courses of software engineering, and all the selected courses have met the national requirements. In the practice of scientific research, I have widely read doctoral and master's theses and a large number of foreign language documents, and have strong practical ability, and participated in many research projects of my tutor. After studying, students pay attention to the improvement of personal comprehensive quality. He once participated in Wuhan University football competition on behalf of the college and won the first place. He often participates in extracurricular activities with his classmates. These activities not only exercised his body and mind, but also deepened the friendship between his classmates. I believe that these experiences and accumulation will become valuable wealth in Hu Guang's life. In the future work and study, I hope this student will continue to maintain and carry forward the rigorous style of study, be conscientious and strive for greater achievements.
