Iron uptake by microcystin-producing and non-microcystin-producing strains of Microcystis aeruginosa was investigated through short-term uptake assays. Although strain-specific differences were observed, the siderophore-independent Fe uptake kinetics were essentially similar (e.g., maximum uptake rates of 2.0 to 3.3 amol·cell(-1)·h(-1)) for the wild-type toxic strain PCC7806 and a genetically engineered mutant unable to produce microcystin.
通过短期摄取实验研究了产微囊藻毒素和非产微囊藻毒素的铜绿微囊藻菌株对铁的摄取。尽管观察到了菌株特异性差异，但铁的摄取动力学基本相似（例如，野生型产毒株 PCC7806 和无法产生微囊藻毒素的遗传工程突变体的最大摄取速率为 2.0 到 3.3 amol·细胞(-1)·h(-1)）。
