| Outline of Final Research Achievements |
Pseudanabaena strains were isolated from Japanese Lakes, ponds and reservoirs. After the taxonomic treatment, we newly described three new species including five taxa. The genes of 16S rRNA and rbcL were varied in these taxa.
The secondary structures of the ITS regions of the rRNA operon, was useful for distinguishing the Pseudanabaena taxa. It was difficult to distinguish these strains by morphological characters.

| Academic Significance and Societal Importance of the Research Achievements |
藍藻類（シアノバクテリア）のプセウドアナベナ属は、カビ臭物質（2-MIB）を産生するため、水道水や2枚貝のカビ臭問題を引き起こす。本研究では、この2-MIBを産生する本邦のプセウドアナベナ属藍藻の分類学的検討を行い、３種５分類群を記載した。日本から見つかった2-MIB産生種はすべて新分類群であった。
従来カビ臭の産生/非産生の判別形質として用いられてきた方法はいずれも使えないことが判明した。
私たちの今回の研究は、今後のカビ臭問題解決のための基盤となる研究であると考えている。
