Course description and aims
On Earth, diverse environments respectively accommodate unique microbiota, and the microbial communities greatly contribute to the global material and energy cycle. In this class, the physiology, ecology, and phylogenetic diversity of environmental microbes, as well as how to investigate them, are outlined, and the applications of environmental microbes are also explained. Prof. Wachi presents the methods of isolation and identification of soil microbes and their applications in agriculture, bioremediation and screening of antibiotics. Prof. Yatsunami explains the ecology of extremophiles and the structures and functions of their enzymes. Prof. Hongoh outlines metagenomics and single-cell genomics of uncultured microbes. Prof. McGlynn explains diverse energy conserving strategies of environmental microbes and outlines arguments on the Last universal common ancestor of extant organisms.
Student learning outcomes
By the end of this course, students will understand and be able to explain the outline of:
1. The phylogenetic diversity, physiology, and ecology of microbes in diverse environments
2. The application of soil microbes in agriculture, bioremediation, and mass production
3. The functions and application of extremophiles
Keywords
soil microbes, extremophiles, applied microbiology, uncultured microbes, metagenomics, energy conservation, origins of life
Competencies that will be developed
| ✔ Specialist skills | ✔ Intercultural skills | Communication skills | ✔ Critical thinking skills | ✔ Practical and/or problem-solving skills |
Class flow
The lectures are given in English by using PowerPoint slides (ZOOM), which will be uploaded prior to each lecture.

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)
None required.
Reference books, course materials, etc.
Brock Biology of Microorganisms (14th edition)
Handouts will be distributed at the beginning of class when necessary and elaborated on using PowerPoint slides.
Assessment criteria and methods
Reports or online exams by each instructor.
If your reports are found to contain materials plagiarized from literature, including the Internet, or reports by other students, your grade will be marked zero, and the University may take further disciplinary action.
