Class Objectives
/Class Outline
This class will introduce the organisms that live in "extreme environment" such as deep sea, deep underground, Antarctica and deserts, and give overviews of biological characteristics with which these organisms have evolved to adapt to extreme conditions. In addition, for the organisms whose genomes and/or proteomes have been analyzed, this class will delve into molecular mechanisms of adaptations and examine their biotechnological applicabilities.

Suggestions on
Preparation and
PDF version of the PowerPoint files that are used in video lectures will be provided; so please use them for your preparations and reviewes of lectures, and watch videos repeatedly as needed.  
Grading Method Grades will be evaluated based on the submission status and content of assignment reports.
3 points will be given to each submission, and a maximum of 45 points will be given to the total of 15 submissions.
And, 1 to 4 points will be added depending on the content of each assignment report, so that a overall total of 60 to 100 points will be given to a total 15 report submissions.  
Practical Experience Experienced  
Summary of Practical Experience and Class Contents based on it I have participated in profesional expeditions to dee-sea, deep underground, Antarctica, Arctic areas, deserts, alpines, caves etc.
Based on these experiences, I think I can provide more concrete and realistic class contents, including examples of extremophiles that I have seen with our own eyes.  
Please fill in the class improvement questionnaire which is carried out on all classes.
Instructors will reflect on your feedback and utilize the information for improving their teaching.
