Impact of extractive chemical compounds from durable wood species on fungal decay after impregnation of nondurable wood species

Popis výsledku v původním jazyce

This study aims at evaluating the antifungal activity of extractive compounds obtained with fexIKA accelerate extraction process. Black locust (Robinia pseudoacacia L.) and African padauk (Pterocarpus soyauxii Taub.) heartwood as well as black locust bark were used as the source material for investigation. After grinding, extraction, impregnation and rapid durability test, the efficiency of extractive compounds was assessed by the mass loss of European beech (Fagus sylvatica L.) samples used for impregnation and as reference samples. Results showed that the extractive compounds obtained from black locust heartwood were able to increase the native durability of European beech from class 5 (i.e. not durable with an average mass loss of 43.6 %) to class 3 (i.e. moderately durable with an average mass loss of 12.7 %), rendering this study's finding encouraging for the future use of extractive compounds as protective agents for wood.
