Lipolytic activity and radial daily growth rate changes during incubation of thermomyces lanuginosus on natural and synthetic fatty substrates.

The aim of the study was to compare lipolytic activity and radial growth rate changes during the incubation of Thermomyces lanuginosus strains on natural (sunflower oil, soybean oil, rapeseed oil, and corn oil) and synthetic (tributyrin, Tween 20, Tween 40, Tween 60, Tween 80, and Tween 81) fatty substrata. The general lipolytic activity index decreased on natural substrata and increased on synthetic substrata during a five-day incubation period. The general daily growth rate changes were found to be similar on both natural and synthetic fatty substrates.
