A. nidulans cclAΔ inhibits the growth of A. fumigatus strains on GMM agar. Both 2-OH-overproducing strains [cclAΔ and alcA(p)::mdpE] prevented hyphal intercalation of the radial growth of both A. nidulans (data not shown) and A. fumigatus wild-type strains. In contrast, the mycelia of wild-type A. nidulans and A. fumigatus strains overlapped with no signs of inhibitory activity. The cclAΔ mdpGΔ strain, which failed to produce 2-OH, showed interactions similar to wild type. All strains were grown on GMM with the exception of the confrontation between A. nidulans alcA(p)::mdpE and A. fumigatus, which was conducted on LMM with cyclopentanone.
