Course description and aims

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.

Student learning outcomes

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

Keywords

Material balance, circulation, wastewater treatment, nitrification, denitrification, methane fermentation, composting, carbon fixation, nitrogen fixation, biodegradation, bioremediation, biomass resources, sustainable society

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

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.

Out-of-Class Study Time (Preparation and Review)

To enhance effective learning, students are encouraged to spend approximately 100 minutes preparing for class and another 100 minutes reviewing class content afterwards (including assignments) for each class.
They should do so by referring to textbooks and other course material.

Textbook(s)

Kankyo Seibutsukougaku (Koudansha Scientific, Unno et al.,) ISBN 4-06-139806-7

Reference books, course materials, etc.

Handouts will be distributed at the beginning of class when necessary and elaborated on using PowerPoint slides. PowerPoint documents that are to be used in class will be made available in advance via the OCW system. Students are expected to use these documents for preparation and review purposes.

Assessment criteria and methods

Midterm exam: 50%, Final exam: 50%
(FY2020) The 7th and 14th classes review what was taught during the classes. The overall grade will be decided based on mid-term and term-end report assignments.
