The production of toxic metabolites by Chaetomium spp. isolated from solis of permanent pasture.
One hundred and two isolates of Chaetomium spp. have been identified from 2563 soil samples collected from permanent pasture at Nappan, Nova Scotia. Chaetomium umbonatum was the Chaetomium species most commonly isolated. Fifty-six of the Chaetomium isolates were grown in the laboratory and the cultures examined for the production of toxic metabolites. The culture filtrates of 12, and extracts of mycelium of 18, of these isolates inhibited bacterial growth. Chetomin was detected in nine mycelium extracts and isolated from four of the mycelium extracts. Chaetoglobosins were isolated from three mycelium extracts.
