Professor / OGASAWARA Wataru
Prof. Ogasawara and Shida are cheerful teachers who guide us sometimes strict and sometimes kindly. We are given various chances such as attending academic conferences and internships at universities and companies. They always encourage us to be independent in research activities.

Research Content

We aim to deepen understanding about the world of microorganisms and how to exploit their promising potential for industrial applications.
Filamentous fungi (mold): Analysis of enzyme production mechanism of filamentous fungi capable of decomposing plant biomass with the aim of producing useful substances.
Oleaginous yeast: Study on the production mechanism of yeast accumulateing lipid in the cell for stable supply of edible lipid.
Bacteria: Drug development for periodontal pathogens and multidrug-resistant bacteria through investigation of proteolytic enzymes.
Screening of microorganisms: Establishment of state-of-the-art culture technology using emulsion and screening for useful microorganisms.

(A)Filamentous fungi, (B)Oleaginous yeast,
(C)Structure of enzyme crystallized in space,
(D)Screening of microorganisms by emulsion

A Day in the Lab

The core time in our laboratory is from 10:00 to 18:00. Seminars are held on every Monday, where students present their research progress and review a publication related to their research theme. We have great opportunities to share our research information with professors and students from other universities or institutes via domestic and international conferences. Because there are many seniors and assistants, we have an environment that supports how to conduct research and how to create presentation materials.


Thesis Subjects
