Abstract
Inhibitory impact of Artemisia herba-alba extract on Klisinema persicum growth was investigated. This study looked at the effects of different concentrations of A. herba-alba extracts on the growth and antioxidant enzyme (superoxide dismutase and Catalase) activity of K. persicum in order to determine the optimal dose range for the good anti-algal action. Concentrations were used (2.5,5, 10, 20, 40,80 and 160) mg. L-1 as well as control. Results showed that both crude extracted, alcoholic extract, and aqueous extract of A. herba-alba had an obvious inhibitory effect on K. persicum growth, as such the obtained results demonstrated A. herba-alba crude extracted inhibited algal growth more efficiently than alcoholic extract and aqueous extract of A. herba-alba. This investigation found that a dose of 10 mg. L-1 with above 50% of IR of extracted crude, alcoholic extractand aqueous of A. herba-alba was best, based on changes in algal cell density and inhibitory ratio (IR). Additionally, after 4 days, the extracted A. herba-alba group saw a significant decline in Chlorophyll-a concentration and antioxidant enzymes activity, falling below the detection threshold. Our findings may pave the way for further investigation into the mechanisms underlying inhibitory effects on dangerous algae, which in turn could lead to the creation of novel anti-algal materials.
