Abstract
There is an increasing demand for novel antibiotics that are highly effective, but simultaneously reveal minimal side effects. Currently, major sources of antibiotics are found among bacterial genus Streptomyces and among fungal genera Penicillium and Aspergillus. Chaetomium represents the largest genus of the family Chaetomiaceae actually containing more than 100 described species. This rather complex genus has been reported as a rich source of secondary metabolite products with important biological activities, such as enzyme-inhibitory, antitumour, cytotoxic, antimalarial and also antibiotic effects. One of them, chaetomin, a part of Chaetomium cochliodes antimicrobial equipment was discovered already in the early period of antibiotics discovery, but later not investigated in sufficient detail. In this contribution we have studied Chaetomium cochliodes Palliser CCM F-232 for its possible antibacterial properties. For comparisons, a closely related fungus Chaetomium globosum was also employed. Antibacterial properties of Chaetomium sp. were tested on natural bacterial isolates of Staphylococcus aureus and Bacillus subtilis. We performed several antimicrobial tests with a correlating output. Antibacterial effects of these filamentous fungi were demonstrated either by the presence of susceptibility zones on solid agar media in the case of S. aureus or by growth inhibition in liquid broth in the case of Staphylococcus aureus and Bacillus subtilis.
