Masaharu Ishi, Ph.D., is a Professor at the Laboratory of Applied Microbiology, Department of Biotechnology, Graduate School of Agricultural and Life Sciences, University of Tokyo. Holding a Ph.D. from the University of Tokyo, his work focuses on the energy and carbon metabolisms in various microorganisms with special emphasis on hydrogen-oxidizing bacteria (Hydrogenobacter thermophilus and Hydrogenophius thermoluteolus).
Satoshi Wakai, Ph.D., is a Scientist at the Institute for Extra-cutting-edge Science and Technology Avant-garde Research (X-star), Japan Agency for Marine-Earth Science and Technology (JAMSTEC), Yokosuka, Japan, and a Guest Associate Professor at the Graduate School of Science, Technology, and Innovation, Kobe University, Japan. He holds a Ph.D. from Okayama University and is currently an associate editor for Microbes and Environments (an open access journal on microbial ecology). His work focuses on the development of diagnostic technologies and molecular mechanisms in microbiologically influenced corrosion, energy conversion of extremophiles, and metabolic engineering for the microbiological production of useful chemicals.
