A new Paecilomyces variotii strain was isolated from the marine habitat. The fungal biomass necessary for the chemical study was produced with success, at a laboratory scale. A total of 28 structural groups were identified from volatile compounds that, in the main, are normal lipid compounds involved in the fatty acid pathway, fragments from their catabolism, terpenoids, and a metabolite from the shikimic acid route. In addition, two non-volatile compounds, triolein and ergosterol peroxide, were isolated and identified by spectroscopy. This is the first report to describe these compounds for the species P. variotii, suggesting its potential use as a natural source to produce nutraceuticals and functional foods.
