Antifungal activities of Avicennia marina and Rhizophora mucronata extract against four fungal pathogens

In vitro assessment of the Antifungal activities were evaluated in this present study for both aqueous and ethanol extracts prepared from leaves of Avicennia marina and Rhizophora mucronata. Antimicrobial tests were carried out by the disk diffusion method. The ethanol extracts of both species had shown antifungal activities on P. pupurogenome, P. chrysogenum, P. notatum, A. niger, A. alternata and Penicillium italicum. However, none of the water extracts showed antimicrobial activity on the studied fungi. Among the all pathogens tested A. flavus was the most resistant fungi. Different concentration of extracts from Avicennia marina and Rhizophora mucronata exhibited different degree of growth inhibition against tested fungal strains. This study indicate capable mangrove species for the utilization as source of natural antifungal
