Research Interests
Interaction between biomolecules and solid surface has been applied to many technical fields such as bioreactor, bioseparation and biosensor technologies. We are aiming to design biointerface where microorganisms make their communities, and apply it to biological wastewater treatment processes. In view of engineering, it is greatly advantageous for wastewater treatment to immobilize microorganisms onto surfaces of small carrier particles and fluidize them in the reactor. A "biofilm", which is a thick layer made up of microorganism clusters, can be obtained by elucidating and controlling an interaction between a microorganism cell and solid surface. We are trying to monitor microbial ecology of biofilms using molecular probes in order to understand their structures and functions, which is expected to enable the successful application for efficient wastewater treatments. Following topics are now investigated.
[Basic and practical study on biofilm]
- Biofilm formation on controlled surface
- Extracellular polymeric substances for biofilm
- Microbial ecology detected by molecular tools
- Mathematical analysis by diffusion-reaction model
- Granule process using aerobic upflow fluidized bed
[Nutrient removal from wastewater]
- Denitrifying phosphorus accumulating organisms
- Autotrophic nitrogen removal in single reactor
- Nitrogen removal from metallurgic wastewater
- Membrane-aerated biofilm reactor
[Treatment of biorefractory wastewater]
- Metal removal using sulfate reducing bioreactor
- Oxidation of organic compounds by UV/H2O2
[Others]
- Isolation and analysis of nonculturable bacteria
- Real-time monitoring of bacterial activity by mRNA
- Novel gene screening by microarray technique
- Wastewater treatment approaching to zero-emission
