Abstract

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.

摘要

本研究的目的是比较羊毛嗜热丝孢菌菌株在天然（向日葵油、大豆油、菜籽油和玉米油）和合成（三丁酸甘油酯、吐温20、吐温40、吐温60、吐温80和吐温81）脂肪底物培养期间的脂解活性和径向生长速率变化。在为期五天的培养期内，天然底物上的总体脂解活性指数下降，而合成底物上的总体脂解活性指数上升。发现在天然和合成脂肪底物上，总体每日生长速率变化相似。
