Inhibition of Aspergillus parasiticus NRRL 2999 by Pollen and Propolis Extracts

Abstract

The inhibitory effects on mycelial growth of Aspergillus parasiticus strain NRRL 2998 of pollen and propolis extracts from different regions of Turkey were investigated in culture media. The least active concentration towards the tested fungus was 2% of both extracts. But, the inhibitory effects of all propolis extracts on mycelial growth were higher when compared with pollen extracts. While the effect of a 5% level of Antakya propolis extract increased with increasing incubation period, the antifungal effect of pollen extract from the same region on mycelial growth was less than that of the control group. As a result, none of the extracts tested completely inhibited mycelial growth. The highest inhibition rate was established at the 5% level of Taşkent and Alanya propolis samples.
