| 1 | Research Status and Progress on Modification of Dietary Fiber at Home and Abroad显示文摘Studies have shown that modified dietary fiber has better physical and chemical properties and functions,and can better play its physiological effects.This paper systematically and comprehensively expounded the application progress of chemical separation method,microbial fermentation method,physical method,enzyme method and steam explosion method in dietary fiber modification,and expounded the development prospect of modified dietary fiber,so as to provide reference for further study on development and application of dietary fiber. | Xiaoran DUAN Suyan GAO Shoumin JIA Litian ZHANG Ruihuan DU Aili XIANG Biao QI Lei WANG | 2019 | Agricultural Biotechnology2019，8，4： | 5 |
| 2 | Preliminary Study on Biological Control of Mycotoxin Contamination in Agricultural Products and Its Mechanism显示文摘Aflatoxin is the most powerful carcinogen and highly toxic mycotoxin known in nature. It can cause serious toxin pollution to agricultural products, foods and fodders, and is extremely harmful to human and animal health. For aflatoxin pollution, the emphasis is on the control of source, and biological control is favored by scientists because of its advantages of environmental protection and ecological safety. According to the morphology, color and appearance of microbial colonies isolated from maize kernels, 300 bacterial strains were obtained from main maize-producing areas including Tangshan City, Handan City, Shijiazhuang City and Cangzhou City. Two biocontrol bacterial strains(B120 and B65) having a strong control effect on aflatoxins were screened. After identification by molecular biology and physical and chemical properties, the two biocontrol bacterial strains were identified as Bacillus amyloliquefaciens. Their effects on spore germination, mycelial growth and toxin degradation of Aspergillus flavus were investigated. The results showed that strains B120 and B65 could significantly inhibit the spore germination and mycelial growth of A. flavus and reduce aflatoxin production. This study provides a new way to prevent and control the pollution control of aflatoxins in agricultural products. | Shoumin JIA Suyan GAO Sining TANG Litian ZHANG Haitao ZHAO Yuli WANG Aili XIANG Zhaoju WU Lixue DONG | 2019 | Agricultural Biotechnology2019，8，2： | 0 |
| 3 | Correlation of Aflatoxin Contamination in Peanuts with Rhizosphere Microorganisms and Its Comprehensive Control显示文摘Aflatoxin contamination is an important hazard factor affecting the quality safety and food safety of peanut production, which seriously threatens people's health and safety. In this paper, the background and harmful causes of aflatoxin contamination were analyzed in detail, with attention focusing on its control measures, which has certain guiding significance for the comprehensive control of aflatoxin contamination. | Suyan GAO Shoumin JIA Litian ZHANG Yi ZHANG Haitao Zhao Aili XIANG Biao QI Lixue DONG | 2019 | Agricultural Biotechnology2019，8，2： | 0 |
| 4 | Brucellosis Outbreak Caused by Brucella melitensis--Jingyang County,Shaanxi Province,China,March–May,2020显示文摘What is already known about this topic?Brucellosis is one of the world’s most overlooked zoonotic diseases,and humans can easily acquire brucellosis from animals and their products.Reemerging brucellosis outbreaks are probably attributable to sociocultural factors and compounded by the lack of adequate control measures in sheep and goat rearing systems.What is added by this report?This is the first identified outbreak caused by Brucella melitensis bv.3 in Jingyang County,Xianyang City,Shaanxi Province.A total of 13 seropositve cases(7 acute patients and 6 asymptomatic persons)were identified from March to May,2020,and the investigation indicated that sheep-to-canine-to-human was the likely transmission route.What are the implications for public health practice?Effective control of sheep brucellosis will significantly reduce the risk of human brucellosis.Priority should be given to building cooperation between all stakeholders,maintaining epidemiological surveillance to detect human brucellosis at medical centers,and making case reporting mandatory for both veterinary and public health services. | Wenhui Chang Yangxin Sun Suoping Fan Cuihong An Shoumin Nie Guozhong Tian Boyan Luo Hongxun Yang Xiaohua Zhai Haiying Tian Jia Zhang Hai Jiang | 2020 | China CDC weekly2020，2，39： | 0 |
