Extracellular Enzymes in Environments (Paperback)

Extracellular Enzymes in Environments: Responses to Collaborative Remediation of Contaminated Soil and Groundwater provides an overview of the functions, activities, and analysis methods of enzymes in soil and water environments. In addition, the response of enzymes to environmental changes (e.g., contamination, remediation, climate change, fertilization) is also summarized based on experimental results. Spatial and temporal distribution of enzyme activities is assessed using in-situ zymography. Furthermore, variation of enzyme activities in hotspots (i.e., rhizosphere, detritusphere) and controlling factors are also summarized.

• Provides detailed information on the in-situ zymography technique, which can visualize enzyme activities in soil and water environments
• Quantifies distribution of enzyme activities in response to nano-metal oxides contamination and use of enzymes to evaluate remediating effect of various carbon-based biomass materials on heavy metal contamination
• Covers the responses of enzymes to environmental changes (e.g., contamination, remediation, climate change, and fertilization) are summarized

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 behaviours of soil contaminants (e.g., heavy metals, microplastics and organic pollutants) and mechanisms of their remediation. Various methods (i.e., in-situ zymography, isotope labelling, 16S sRNA sequencing and so on) are involved in these studies. He has published 35 academic articles and presided or precipitated over 10 projects. He also serves as the youth editorial board members of several Chinese journals, i.e., Soil, Chinese Journal of Soil Science, Journal of Agricultural Resources and Environment and review editor for Frontiers in Environmental Science.
