Abstract

The study involved the isolation, purification and culturing of the cyanobacterial Chroococcidiopsis cubana from the Shatt al-Arab River in the Basrah Governorate, southern Iraq. The growth curve of Ch. cubana was schemed after its cultivation in the liquid culture medium BG-11. The growth analysis indicated a growth constant (k) = 1.3 and a generation time (G) = 0.5 days. Ch. cubana ability to produce hepatoxic microcystins (MCs) was detected after isolating and purifying the toxins. The toxins were determined quantitatively and qualitatively using the technique of High-Performance Liquid Chromatography (HPLC), which revealed that Ch. cubana exhibited a high production capacity of these toxins, with a concentration rate = 4.053 ug/l.
