Effect of Spirogyra fluviatile Alga Extract on Aspergillus carbonarius Pathogenic Fungus

Abstract

Spirogyra. fluviatilis was collected from the Damascus Ghouta region (Deir Al-Asafir), Damascus countryside governorate. Extraction was carried out using distilled water, methanol and chloroform as solvents. The total content of phenols and flavonoids in all extracts was calculated. The effect of different extracts concentrations on Aspergillus carbonarius was investigated. The highest content of phenols and flavonoids was in the methanol extract and reached 236.6±0.89 and 86.47±0.14 mg/g, respectively, and the highest inhibition rate reached 81.05% for the methanol extract at a concentration of 100 mg/ml, and the lowest inhibition rate was 67.89% for the water extract at a concentration of 60 mg/ml.
