Extracellular Enzymes in Environments

Professor and doctoral supervisor, is currently the deputy dean of the School of Ecology and Environment, Chengdu University of Technology. He has been engaged in research on the theory and technology of coordinated groundwater restoration of polluted sites for more than ten years. Research fields include the interactive pollution process of pollutants in water and soil media, the adsorption/desorption, migration transformation and fate behavior mechanism of water-soil-biointerface; collaborative control and joint restoration technology based on multidisciplinary theories and methods. At present, he has published more than 110 academic papers and more than 20 patents; he has presided over 5 projects of the National Natural Science Foundation of China, 1 project of the National Key R&D Program, and more than 20 other projects. He has been selected as a Xiangjiang Scholar, Sichuan "Thousand Talents Program" Rongpiao Program, etc.; won the first "Young Scientist Award" of the Chinese Society for Environmental Sciences; the first prize (2020) and the second prize (2019) of the National Environmental Protection Science and Technology Award each item Shibin Liu is an Associate Professor at Chengdu University of Technology. He got his Master’s degree from Northwest University of Agriculture and Forestry and his PhD degree from the Department of Soil Science of Temperate Ecosystems, University of Göttingen. Dr Liu’s research focuses on the mechanisms of soil degradation and restoration. His main research areas include: (1) Effect of grassland degradation and subsequent restoration on soil properties and plant characteristics in the Tibetan Plateau. (2) Influence of organic fertilizer and its pyrolyzed biochar on soil biochemical properties and plant growth; (3) Fate and environmental behaviors of soil contaminants (e.g. heavy metals, microplastics and organic pollutants) and mechanisms of their remediation. Various methods (i.e. zymography, isotope labelling, 16S sRNA sequencing and so on) are involved in these studies. He has published 27 academic articles and presided or precipitated over 10 projects.
