Abstract
The purpose of the work was to investigate the ability of the Penicillium fungi to synthesize nitrogen-containing mycotoxins. Most fungi of the genus were shown to produce various classes of mycotoxins such as ergot alkaloids, diketopiperazines, quinoline alkaloids. The dependence of the activity of the producer on cultivation conditions and their physiological states were investigated. Methods of isolation, purification and analysis of both previously known and new mycotoxins were developed.
