Study the effect of some algae extracts against activity of some fungi

Abstract EN

Study is carried out to investigate the effect of algae extracts on the activity of some fungi (Trichophyton rubrum ; Aspergillus flavus ; Microsporium canis and Cryptococcus neoformans).

The minimal inhibitory concentrations (MIC) of algae against fungi were for Oscillatoria irrigua (blue green algae) (150-250μg / ml) less than it's for Scenedesmus quadricauda (green algae) (400 μg / ml).

Also the minimal cidal concentrations (MCC) were at the same above trend for algae.

The inhibition zones diameters were for Oscillatoria irrigua extract varied between (5-33) mm and for Scenedesmus quadricauda ranged between (2-24) mm, results showed no mortality occur in experimental animals after injected by high concentrations of algae extracts.

Generally, study concluded the effects blue-green algae extracts on fungi activity were higher than its for green algae extracts ; and the Cryptococcus neoformans (yeast) was significantly (p < 0.01) more sensitive somewhat to algae extract then other studied filamentous fungi.
