FIG. 1.

Effect of initial treatments (microwave and nutrient addition) of Oostvoorne dune soil on temporal dynamics of the hyphal extension ability of Chaetomium globosum (A) and Fusarium culmorum (B), soil respiration (C), and bacterial CFU (D). Hyphal extension from potato dextrose agar disks into soil was measured at all indicated time intervals and is given as a percentage of the extension measured into acid-purified beach sand. Symbols: •, control; ○, microwave; ▪, tryptic soy broth; □, acetylglucosamine; ▴, glucose.
