RT @amikura1986: 謎の極小微生物CPR/DPANNとリボソームについて、生物工学会誌のバイオミディアに書きました.分野発展の一助となれば幸いです.校閲者の先生方にはここで感謝申し上げます.尚,昨年はCPR/DPANN研究会が発足しました.会の情報交換用Slack…
70度の高温条件で窒素固定をするバクテリアは、以前の研究 (Nishihara et al. 2018)に続き2例目になります。 https://t.co/DB87MnVuiu
論文が公開されました: https://t.co/pB801Bb8nR 本研究では、Firmicutes門に属するCaldicellulosiruptor属細菌の一種を新たに分離し、70度の高温条件で窒素固定をすることを示しました。
This is the second report of a bacterium that performs nitrogen fixation under high temperature conditions of 70°C, following the previous report (Nishihara et al. 2018): https://t.co/DB87MnVuiu
Our paper is now available online: https://t.co/pB801Bb8nR We isolated thermophilic fermentative bacterium belonging to the genus Caldicellulosiruptor. The isolate demonstrated nitrogenase activity at 70ºC despite of harboring imcomplete nif gene sets (lacking NifN).

In 3rd paper, nitrogenase activity in the isolates belonging to the Aquificae phylum was detected. To the best of our knowledge, this is the first demonstration of active nitrogen fixation in thermophilic bacteria at 70°C and in the phylum Aquificae. https://t.co/xkbQM95wY4
In 2nd paper, candidate nitrogen-fixing bacteria were examined in the community, where nitrogenase was detected. https://t.co/Em4aAGIMae
1st paper is about the detection of nitrogenase activity in the microbial mats (thick biofilms) at 70ºC in the terrestrial hot springs. https://t.co/r43yhaEbnK
