A Variety of BFU Academic Achievements Honored with Liangxi Forestry Science and Technology Awards

2020-11-18

On October 25, 2020, the list of winners of the 11th Liangxi Forestry Science and Technology Awards was announced; 19 projects led by Beijing Forestry University (BFU) won the Awards. Among the awarded projects, 10 were accomplished with BFU as the first completion unit, including one with first prize of Natural Science Awards, one with first prize of Technological Invention Awards, six with second prizes and two with third prizes of Science and Technology Progress Awards. Professor John Innes, Dean of the Faculty of Forestry at University of British Columbia of Canada, won the International Science and Technology Cooperation Award. He has been a leading figure of a major institution in longtime cooperation with BFU. 

 

Among the awardees, Professor Dai Yucheng and his team of the Institute of Microbiology at BFU School of Ecology and Nature Reserve completed the “Research on Diversity and Resources of Wood-decay Fungi in Southwest China”, which won the first prize of the Natural Science Awards, which is the first project that has ever received the first prize of the awards. From 2004 to 2016, Prof. Dai’s team conducted an in-depth and systematic research on the diversity and resources of wood-decay fungi in Southwest China, discovering and publishing one new family, five new genera and 100 new species of fungi, which made an important breakthrough in the research of species diversity.

 

The finding greatly enriched the diversity of wood-decay fungi nationwide as well as worldwide, putting the research at the leading position of the world. At the same time, the polygenic phylogeny analysis of five new genera was carried out, and the phylogenetic and evolutionary relationships between these genera and their corresponding groups were constructed, which made the research on these fungal groups in China attain the world-class level. In addition, compared with those before the research started, the total numbers of wood-decay fungi, medicinal wood-decay fungi and pathogenic wood-decay fungi in Southwest China increased by 2.9, 3 and 2.8 times respectively. The research provides a theoretical basis for the development of medicinal fungi industry and the prevention and control of forest diseases. 

 

Another project, “Key Techniques for Green Separation and Full-Quality Utilization of Fibrous Biomass”, led by Professor Xu Feng at College of Material Science and Technology of BFU, won the first prize of the Technological Invention Awards. Aiming at the technical bottleneck issues of low separation efficiency, high environmental protection load and low added value of fiber biomass, the project successfully developed the green separation techniques for main components of solid alkali catalysis/active oxygen, and converted the separation components into water-soluble cellulose, eco-friendly lignin resin and other materials, realizing the green separation and full-quality conversion of fibrous biomass. These achievements have formed key techniques with independent intellectual property and have been widely applied in such fields as pulp and paper making, cellulose purification and plate processing in China. The large-scale industrial production is of great significance for promoting the utilization of fibrous biomass, improving the added value of products and environmental benefits. The project proposed the in-situ Raman microscopic detection for the regional distribution of hemicellulose, stripped off the overlapping Raman signals of hemicellulose and cellulose with great accuracy and efficiency, invented the technique of solid alkali catalysis / active oxygen separation of wood and gramineae materials, achieved the clean and efficient separation of main components and the joint production of organic fertilizer, created such new productions as high-quality refined cellulose products, water-soluble cellulose and resin barrier inhibitor, and eco-friendly lignin-based resin. The research has established the value-added processing of fibrous biomass, significantly improved the utilization rate of resources, as well as solved the problem of environmental pollution in the traditional biomass processing.

 

The Liangxi Forestry Science and Technology Awards, as is known, ranks as the highest science and technology award in forestry industry approved by the Ministry of Science and Technology of China. It represents an important component in the discipline evaluation system of the Ministry of Education. This year witnessed 103 awards being granted, of which 9 Natural Science Awards (including 2 first prizes and 7 second prizes), 5 Technological Invention Awards (including 1 first prize and 4 second prizes), 89 Science and Technology Progress Awards (including 6 first prizes, 57 second prizes and 26 third prizes). In addition, three experts abroad won the International Science and Technology Cooperation Award.
