AboutAbout the lab
Tackling resource and environmental challenges with the power of living organisms
The Resource Bioengineering Lab works to solve problems of resources, the environment, and energy by using and imitating the remarkable functions of the many kinds of organisms found in nature.
It uses the ability of microorganisms and other organisms to adsorb metals to remove harmful metals from the environment and to recover valuable metals from urban mines.
Learning from beachrock, the rock formed when sand and gravel on a seashore naturally harden, the lab has also developed a technique that uses microorganisms to solidify soil in a short time.
Key terms
- Biosorption
- A technique that uses components on the surface of cells, such as those of microorganisms, to bind and collect metal ions
- Urban mine
- The idea of treating waste accumulated in cities, such as used home appliances and electronic devices, as a "mine" of metal resources
- Beachrock
- Rock formed when sand and gravel on a seashore are naturally cemented by calcareous materials such as calcium carbonate

ResearchResearch themes
The lab works to solve problems of resources, the environment, and energy by using and imitating the remarkable functions of the diverse organisms found in nature, with fresh ideas. It pursues research on collecting metals with living organisms and research on solidifying ground with microorganisms.
*Illustrative imageCollecting Metals with Living Organisms
Proteins and polysaccharides on the surface of cells can attract and adsorb positively charged metal ions. Using this biosorption, the lab works on removing harmful metals from the environment, recovering valuable metals from urban mines, and analyzing the interactions between metals and microorganisms. With genetic engineering, it is also possible to design microorganisms that adsorb only specific metals.
*Illustrative imageGround Solidification Inspired by Beachrock
Some beachrock in Japan has turned into rock within a few decades. The lab found microorganisms suited to precipitating calcium carbonate around beachrock in Okinawa Prefecture, and used them to develop a technique that hardens soil into rock- or concrete-like material in a short time. Its effectiveness has also been confirmed with coral sand from the coasts of Okinawa Prefecture.
