Coal ash of more than 8000 thousand tons generates a year in Japan. It is classified by fly ash and clinker ash. As a new treatment method, bioremediation was applied to the fly ash. It was found that concentration of Cr (VI) can be reduced by mixing the microorganisms such as lactic acid bacteria, yeast and bacillus natto. The reducing effect was nearly connected with a quantity of the microorganisms. Furthermore, one of potential bacteria was selected from coal ash damping site. The strain exhibited high boron resistance. The strain was capable of removing boron from the artificial medium containing boron. It is expected that these microorganisms are useful for remediation of fly ash.
