Metabolites of Trichoderma species isolated from damp building materials.

Buildings that have been flooded often have high concentrations of Trichoderma spores in the air while drying. Inhaled spores and spore and mycelial fragments contain large amounts of fungal glucan and natural products that contribute to the symptoms associated with indoor mould exposures. In this study, we considered both small molecules and peptaibol profiles of T.

Fungal Planet description sheets: 371-399.

Novel species of fungi described in the present study include the following from Australia: Neoseptorioides eucalypti gen. & sp. nov.

First Report of "Candidatus Phytoplasma asteris"-Related Strains in Brassica rapa in Saskatchewan, Canada.

"Candidatus phytoplasma asteris" and related strains (i.e., aster yellows group 16SrI) have been associated with diseases of numerous plant species worldwide.

Glucanolytic Actinomycetes Antagonistic to Phytophthora fragariae var. rubi, the Causal Agent of Raspberry Root Rot.

A collection of about 200 actinomycete strains was screened for the ability to grow on fragmented Phytophthora mycelium and to produce metabolites that inhibit Phytophthora growth. Thirteen strains were selected, and all produced (beta)-1,3-, (beta)-1,4-, and (beta)-1,6-glucanases. These enzymes could hydrolyze glucans from Phytophthora cell walls and cause lysis of Phytophthora cells.
