Inhibition of fungal growth and sporulation by volatile metabolites from bacteria

Abstract

Volatile metabolites produced by eight bacterial species greatly inhibited growth and sporulation of all fungi tested, namely Fusarium oxysporum f. conglutinans, Gelasinospora cerealis, Penicillium viridicatum, Trichoderma viride, and Zygorhynchus vuilleminii. Alterations of colony morphology were induced in all test fungi, except G. cerealis. In P. viridicatum, colony contour and color were altered; in F. oxysporum f. conglutinans, T. viride, and Z. vuilleminii, the amount or distribution of aerial growth was altered.
