Study alcoholic extract effecting of Actinidia in the growth of two types of algae Microcystis sp. & Chroococcus sp.

Abstract

The main objective of this study is examine the effect of (Actinidia) Kiwi Peel extract against growth two species of blue-green algae(Cyanobacteria) : Chroococcus sp and Microcystis sp. the growth rate of algae counted directly by Chamber. The algae farms were dividedin to Three groups as following : the first group(C1): Treatment control concentration 0% , the second group(C2): Treatment of alcoholic extract concentration of the Kiwi plant  1%  , the third group( C3): alcoholic extract concentration of the Kiwi plant  5% . All groups were noted during the time periods.

The results showed the (Actinidia) Peel extract caused a significant inhibition (p<0.05) in the rate of growth of algae at concentration 5% for two species, and the colonies  were reached in Microcystis sp (72) cell in ml compared with control , in Chroococcus sp. was least cells (60 ). Microcystis sp was more resistance for Actinidia Peel extract.
