Outline of Final Research Achievements |
An anoxic enrichment culture from sandy sediment was established with toluene as a carbon source. An aerobic anoxygenic phototroph (AAnP) was isolated from the enrichment culture. AAnPs are so far unknown to be involved in aromatic hydrocarbon degradation. In this study, we analyzed its functional characteristics and a draft genome sequence of the newly isolated strain. The unique physiological characteristics and genetic makeup and provide hints for understanding the involvement of AAnPs in the aromatic hydrocarbon degradation.

Academic Significance and Societal Importance of the Research Achievements |
光照射のみで芳香族炭化水素を分解できる光合成細菌の多様性を解明し、新規集積培養株を得ることは、将来的な光合成細菌のバイオレメディエーションへの利用の幅を広げる。集積培養株を得られたことで、これまで1種しか知られていなかった芳香族炭化水素分解光合成細菌の多様性と、その生理学的な機能の詳細な検討が可能になった。また得られた単離株は系統的に新規な微生物として記載できる可能性がある。
