Abstract
|
|
|
|
S. chartarum, a toxigenic mould, can produce various volatile chemicals which collectively are termed microbial volatile organic compounds (MVOC). To identify and characterize MVOC production, S. chartarum spores were inoculated onto sterilized gypsum boards containing 2 lbs/msf borate preservative or no added borate control. Mould growth was monitored by weekly changes in MVOC profiles by SPME on a gas chromatograph with flame ionization detector. MVOC were identified and confirmed using gas-chromatography/mass spectroscopy. A variety of compounds were produced by S. chartarum on gypsum board, including ketones such as acetone, anisole (the main metabolite), terpenes and sesquiterpenes, and trichodiene, pre-cursor of the tricothecene. The anisole peak was detected beginning at 15 days of incubation, and reached a maximum at 35 days incubation, and then gradually decreased. Borates were effective at preventing or reducing mould growth. Borate-treated materials appeared to be resistant to S. chartarum growth and no anisole was detected.
