Abstract

A filamentous, heterocystous, nitrogen-fixing marine cyanobacterium, Anabaena torulosa, has been shown to harbour surface associated, acid soluble polyphosphate bodies. Uranium immobilization by such polyphosphate bodies, reported in cyanobacteria for the first time, demonstrates a novel uranium sequestration phenomenon.

摘要

已证实，束丝鱼腥藻是一种具有异形胞、固氮功能的海洋蓝藻，其体内含有与表面相关、可溶于酸的多磷酸盐体。这种多磷酸盐体对铀的固定作用在蓝藻中尚属首次报道，它展示了一种新型的铀螯合现象。
