Man-made chemical compounds did not exist in previous environment and it is presumed that microbe that degrade the compounds, are rapidly evolving the degradation ability during the past several decades. Therefore, it is expected that a precious knowledge on the evolutionary mechanism of bacteria can be obtained when the microorganisms that degrade those chemical compounds are examined. From this viewpoint, this Microbial Evolution Project was conducted.
As a result, various new PCB-degrading bacteria were identified and those enzymes and genes were examined. Consequently, the concept of the multi-gene family of degradation genes was clarified for the first time, enabling successful analysis of degradation mechanism of the powerful PCB-degrading bacteria and elucidation of the three-dimensional structure of the degrading enzyme.
