The natural environment on Earth is the only space where we and all living beings can survive. However, with the advancement of industrial civilization and the continuous expansion of human society, the Earth's environment poses a huge threat to humans and other living organisms, becoming a highly challenging issue faced by countries around the world. According to the definition by the European Federation of Biotechnology in 1919, "environmental biotechnology is a comprehensive science that combines biochemistry, microbiology, and engineering technologies, with the primary aim of utilizing microorganisms and plants and animals in fields such as agriculture, environment, industry, and healthcare, to promote sustainable development." Therefore, "environmental biotechnology" is an emerging discipline that closely integrates modern biotechnology with environmental science and engineering. It has developed into a systemic engineering technology aimed at the sustainable use of environmental resources, covering upstream and downstream technology integration, and has become a new growth point in global economic development. As a result, it is hoped that students taking this course will engage in immersive learning that continuously extends and expands their understanding of the bio-environmental protection industry alongside the rapid development of modern biotechnology. This course focuses on introducing bioremediation techniques for environmental pollution, biological remediation technologies for environmental pollution, and biotechnologies for preventing environmental pollution. The course content includes theoretical analysis and introduces the latest research advances and development trends both domestically and internationally.
