| Outline of Final Research Achievements |
We studied on behavior of environmental bacteria in microbial community and oligotrophic growth state by using a bacteria degrading recalcitrant organochlorine insecticide and a microbial community from which the bacterial strain was isolated as models. We showed (i) the importance of non-degrading bacterial strains in the community and (ii) the generality of the phenomenon that environmental bacteria can grow on the solid minimal salt medium without addition of any carbon source accompanying CO2 fixation by expression of the alcohol dehydrogenase gene, and obtained a lot of knowledge leading to the elucidation of the mechanisms of these phenomena. A theoretical foundation for the practical application of bacteria in real environments has been established.
