Abstract:
In the current work, the cyanobacterium A. doliolum was pre-exposed to copper chloride (5 µM) for a range of time duration—24 hours, 48 hours, and 72 hours—and then treated with doses of 150 and 200 mM NaCl to better understand how pre-exposure modifies the physiologic activities of the A. doliolum. The findings show that the test cyanobacterium's cellular components did not significantly change after being pre-exposed to copper chloride for 24 and 48 hours. However, the pre-exposure produced an enhanced profile of proline and antioxidant enzymes. The findings demonstrated the detrimental effects of salinity and copper on the development of the cyanobacterium A. doliolum as well as the significance of pre-exposure in the control of the cellular antioxidant machinery.
