  • My thesis focuses on the antifungal properties and chemical composition of extractives obtainable from the bark and knots of Finnish pine. Bark and knots were specifically chosen because both contain large amounts of extractives and are industrial side-products of low value. My results show that knot extract is rich in antifungal compounds and can reduce the growth of fungi, whereas bark extract has no antifungal properties.
