Inhibitors of aquatic and aero-aquatic hyphomycetes in pine and oak wood

Abstract

Addition of pine and English oak wood powder to agar depressed the mycelial growth of nine aquatic and two aero-aquatic Hyphomycetes and spore germination of three aquatic Hyphomycetes. Both powders were highly effective in depressing the growth of Aegerita Candida, Dactylella aquatica, Tetracladium marchalianum and T. setigerum , and spore germination of Dactylella aquatica . They were least effective as inhibitors of Heliscus lugdunensis and Lemonniera aquatica . Inhibition is stronger with pine powder than with oak powder, and the inhibitory effects were reduced or completely lost in leached powders.
