| Abstract | ||
| A cyanobacteria strain Chroococcus sp. was isolated from moist land (Abo Al-Khasib) in Basrah city purified and exposured to different concentrations (3, 5 and 10ppm) of Copper(Cu+2) and Nickel (Ni+2) ions as singly and in dual combinations. Chlorophyll-A was extracted at different exposure periods (0, 1, 2, 3 and 4) weeks as indicat the growth response. Results showed that growth response of cyanobacterium Chroococcus sp. was depending on the ions concentration and the exposure periods the effect of Nickel ions on growth response of Chroococcus sp. isolate better than Copper ion expertly in 1st week exposure while the antagonistic (increasing of growth) effect was appeared at most treatments in dual compaction and synergestic (decreasing of growth) effect in some, the synergistic effect of dual compaction in increasing of Copper ion concentration compared with Nickel ion also, the antagonistic effect was appeared at most treatment in dual combinations. Synergestic or antagonistic effect was depending on the concentration of each ion and the exposure periods | ||
