| Abstract: | Oospora lactis was found to use Tweens 20, 40, 60 and 80 as a source of carbon in a nutrient medium for lipase biosynthesis. The highest production of lipase was registered in the medium with Tween-80. The lipase activity of the culture increased if even small quantities of Tweens 40, 60 and, particularly, 80 (0.05--1.0%) were added to the medium containing cottonseed oil. All the tested Tweens stimulating the biosynthesis of lipase were also, at a particular concentration, the inhibitors of this enzyme. |
