Diverse microbial energy metabolisms in anaerobic environments


Microorganisms have a surprisingly diverse variety of energy metabolisms and novel metabolic pathways are still discovered in recent years. Our research group conducts fundamental and applied studies on microbial energy metabolisms in anaerobic environments. Our main research targets are:

  1. Energy metabolisms by electron exchange with solid conductive materials,
  2. Methane/acetate generation involved in corrosion of iron,
  3. Methanogenic degradation of crude oil and coal in deep subsurface environments, and
  4. Anaerobic wastewater treatment.
