炭素飢餓および光照射条件は紅色光合成細菌Rhodopseudomonas palustrisの浸透圧ストレス抵抗性を上昇させる

新井 沙和, 菅野 菜々子, 松浦 克美, 春田 伸 首都大学東京大学院理工学研究科生命科学専攻 炭素源の枯渇によって飢餓状態になると、高温や高浸透圧、酸などのストレスに対する抵抗性が上昇することが、病原細菌や土壌細菌で報告されている。このような飢餓によるストレス抵抗性の上昇は、自然環境中で微生物が生残性を維持するのに重要な機構のひとつだと考えられる。我々はこれまでの研究で、光合成細菌が炭素源飢餓条件でも光照射があれば、長期間、高い生存率を維持することを報告しており、光エネルギーが飢餓生残に有効であることを示している1)。本研究では、土壌や水圏に広く分布する紅色光
