Abstract
Chaetomium-like fungi growing on indoor building materials produce toxic substances. Fourteen toxigenic indoor Chaetomium-like isolates from buildings in Finland where investigated. Six Chaetomium globosum-like strains from indoor dusts were toxic with boar sperm assay and cytotoxic to porcine kidney cells (PK-15), emitted green fluorescence and produced chaetoglobosins inhibiting cellular glucose transport. OT7 and OT7b strains fromindoor dust were cytotoxic to PK-15 cells, non fluorescent and produced the extremely cytotoxic protein synthesis inhibitor, chaetomin. The six Chaetomium globosum-like strains were resistant to borax and very sensitive to the wetting agent genapol used in cleaning chemicals. This may indicate that indoor Chaetomium-like fungi occupy their own ecological niche in buildings.
