Thymol is a renewable substance and has a high antimicrobial efficiency, which indicates that it could be used to produce sustainable biacides. ln this study, we used kraft lignin as a partial replacement for a traditional surfactant in order to solubilize thymol in water. ln this sense, this article reports an unprecedented method for using a kraft lignin solution to stabilize a thymol-based biacide with high fungicida! activity. The results showed that the lignin was crucial for stabilizing the suspensions. When the lignin was not added to the surfactant, there was a water-oil phase separation and the thymol crystallized after its rest for 30 days. Results obtained by in vitro experiments indicated that one of the studied lignin: thymol suspension {volume ratio of 1 :0.1) presented an excellent fungai resistance. Furthermore, even the sample with the smallest thymol concentration (e.a. 0.5%) was able to inhibit the mycelial growth of the bracket fungus (Ganoderma applanatum), which is a promising feature for a biacidai application. |
