在日本西湖的超寡营养中检测了颗粒有机磷 (P) 化合物。使用筒式过滤器收集足够量的悬浮颗粒，用于通过二维 NMR（1H-31P 异核多重键关联）进行分析。在西湖的悬浮颗粒中检测到了磷酸盐 2-氨基乙基膦酸 (2-AEP)。通过与市售化合物比较，证实了膦酸酯的身份。由于 2-AEP 具有生物利用度，因此微生物可以在磷极其有限的条件下储存和使用该化合物。这是第一项在超寡营养环境中检测 2-AEP 的研究。
Particulate organic phosphorus (P) compounds were examined in ultraoligotrophic Lake Saiko, Japan. A cartridge filter was used to collect sufficient amount of suspended particles for analysis by a two-dimensional NMR (1H-31P heteronuclear multiple bond correlation). 2-Aminoethylphosphonic acid (2-AEP), a phosphonate, was detected in suspended particles in Lake Saiko. The identity of the phosphonate was confirmed by comparison with a commercially available compound. Because 2-AEP is bioavailable, microorganisms can store and use this compound under extremely P-limited conditions. This is the first study to detect 2-AEP in an ultra-oligotrophic environment.
