Abstract:Environmental biotechnology, as an emerging interdisciplinary subject combining modern biotechnology and environmental engineering, has been widely used in environmental pollution control and environmental monitoring. Efficient purification of environmental pollution and the production of useful substances have the potential to fundamentally solve environmental problems. In the present special issue, the principle and application of environmental biotechnology in the field of environmental pollutant degradation such as polycyclic aromatic hydrocarbons, antibiotics, and petroleum-based plastics has been summarized. Application of indole, microbial iron carrier and other molecules in bioremediation has been introduced. Hope to give a comprehensive view on basic environmental biotechnology, future research directions and comprehensive governance strategies.
