Our modern society is depending on adequate supply of energy, clean and safe water, air, and foods, and essential materials, as well as efficient waste management for preservation of a global environment. Environmental Bioengineering is a branch of biotechnology whose objective is to utilize biological functions for the preservation and remediation of a global environment.
This course covers several biological functions (mainly microbial functions) regarding the following topics: global cycles of major elements; metabolisms of carbon, oxygen, nitrogen, phosphorous, and others; biodegradation of wood resources and some environmental pollutants; bioremediation of polluted environments. The course concludes by discussing the conrtibution of the biological functions to establishment of sustainable society, such as production of biofuels and biomaterials from renewable biomass resources.
By the end of this course, students will be able to:
1. Understand material balance and circulation of carbon and water in a global environment
2. Explain metabolisms of nitrogen, phosphorous, and others in water environments and application of them to wasterwater treatment
3. Explain metabolisms of carbon, oxygen, nitrogen, and volatile compounds in gaseous environments
4. Explain biodegradation of wood resources and some pollutants in soil environments
5. Understand the contribution of the biological functions to establishment of sustainable society, as well as discuss about sustainable development of society

|Intercultural skills||Communication skills||Specialist skills||Critical thinking skills||Practical and/or problem-solving skills|
The lecture will proceed along with reviewing of basic knowledge of biochemistry, molecular biology, microbiology, and genetic engineering, as well as summary of the previous class. When necessary, the points in this class will be given by questioning and students will be asked to answer the questions. It is strongly recommended to read syllabus and the corresponding part in the text before the class.
