Volatile compounds in the aroma of three species of wood-rotting basidiomycetes and their antifungal potential
Journal Title: Journal of Plant Development - Year 2017, Vol 24, Issue
Abstract
rotting basidiomycetes: Coriolopsis gallica, Megacollybia platyphylla and Lentinus arcularius and test their antifungal potential. The species were cultivated on liquid media and kept for 25 days at 25 °C. The surface cultures were then homogenized, filtrated and extracted using solid-phase extraction and analyzed by GC-MS. The volatile compounds identified were mainly alcohols, ketones, aldehydes and terpenes. The most common volatiles identified in the experiment are: 1-octen-3-ol, 3-hexanol, 3-methyl-1-butanol, 3-octanone, 2-hexanone, benzaldehyde, and limonene. The volatiles metabolites of these species were tested for their antifungal activity using the bi-compartmented Petri dishes method against two species of plant pathogenic fungi: Fusarium solani and Sclerotinia sclerotiorum, on three media. The volatiles produced by Coriolopsis gallica showed the highest antifungal potential against the phytopathogens. The results revealed the importance of media composition in the synthesis of antifungal volatile compounds.
