Study alcoholic extract effecting of Punica granatum L. plant in the growth of two types of algae Microcystis sp. & Chroococcus sp.

Abstract

The present study was conducted to identify liveliness effect the alcoholic extract of medical pomegranate plant was stimulate or inhibition for growth two species of blue-green algae(Cyanobacteria) : Chroococcus sp and Microcystis sp. the growth rate of algae counted directly by Chamber.to add alcoholic extract concentration of pomegranate(pith and peel) ......٪ (1,3,5,8 ) was 8% the highest efficacy in inhibition for two species and the less colonies were reached in Microcystis sp (100,98) cell in ml compared with control , in Chroococcus sp. was least cells (64,50 ). Microcystis sp was more resistance for alcoholic extract of pomegranate(pith and peel) from another species . observe increase in inhibition for increase the time periods and alcoholic extract of pomegranate peel the highest efficacy in inhibition from alcoholic extract of pomegranate pith for two species.
