چکیده

Chaetomium globosum is frequently isolated in water-damaged buildings and produces two mycotoxins called chaetoglobosins A and C when cultured on building material. In this study, the influence of ambient pH on the growth of C. globosum was examined on an artificial medium. This fungus was capable of growth on potato dextrose agar ranging in pH from 4.3 to 9.4 with optimal growth and chaetoglobosin C production occurring at a neutral pH. In addition, our results show that sporulation is favored in an acidic environment.

The possible role of fungal contamination in sick building syndrome.

The following is a review of some of the work that we have done since 2007 regarding the importance of molds in the phenomenon of sick building syndrome (SBS). In these studies we first examined mold contamination in air handling units (AHU). Our results showed that Cladosporium sp. were commonly recovered in AHU as growth sites and free spores. They were found mainly on the blower wheel fan bl...

Adaptation of marine derived fungi , Chaetomium globosum ( NIOCC 36 ) , under alkaline stress using antioxidant properties

The fungi are an exceptionally useful model in elucidating the cell functions under extreme conditions (temperature, salinity, pH values) and mechanisms underlying adaptation to those extreme environmental conditions. Here, Chaetomium globosum was examined for its adaptation mechanism under alkaline stress using antioxidant properties. The aqueous extracts of C. globosum exhibited different lev...
