Volatile organic compounds (VOCs), 2-methyl-1-butanol, 3-methyl-1-butanol and 2-phenylethanol, were detected together with β-cyclocitral from the cyanobacterium Microcystis aeruginosa NIES-843. These alcohols were optimally produced after 35 d of culture, during which nitrate nitrogen in the cultured broth became exhausted. Additionally, these alcohols were definitely produced using the 2-keto-acid decarboxylase (MaKDC) in Microcystis strains. These results suggested that these VOCs from Microcystis are significant for their lifecycle, because these compounds are not produced by any other genus of cyanobacteria. This is the first report of 2-keto-acid decarboxylase producing 3-methyl-1-butanol and 2-phenylethanol by an oxygenic photosynthetic microorganism.
挥发性有机化合物（VOCs）、2-甲基-1-丁醇、3-甲基-1-丁醇和 2-苯乙醇，与β-环柠檬醛一起从蓝藻铜绿微囊藻 NIES-843 中被检测到。这些醇在培养 35 天后最佳产生，在此期间，培养物中的硝酸氮耗尽。此外，这些醇是在微囊藻菌株中使用 2-酮酸脱羧酶（MaKDC）绝对产生的。这些结果表明，这些来自微囊藻的 VOCs 对其生命周期很重要，因为这些化合物不是由任何其他蓝藻属产生的。这是首次报道有氧光合作用微生物产生 3-甲基-1-丁醇和 2-苯乙醇的 2-酮酸脱羧酶。
