Copper toxicity to cyanobacteria and its dependence on extracellular ligand concentration and degradation

Abstract

Copper toxicity to the cyanobacteriumPlectonema boryanum (UTEX 594) has been investigated in the presence of citrate and nitrilotriacetic acid (NTA) using a copper-saturated culture medium. The coppercitrate complex was biodegradable, and toxicity was dependent on the free ligand concentration. The ratio of citrate to copper also affected the extent of… (More)
