Application of Biological-Based Antifungal Agent for Controlling the Growth of Wood Decaying Fungi of Rubberwood

Article Preview

Abstract:

Rubberwood played a crucial role in industries development in Malaysia, particularly in furniture sector. Preservative of rubberwood becomes important tool in order to obtain an environmental friendly antifungal agent. Thus, biological-based control agent was an alternative way to solve this issue. This study was conducted on the bio-production of antifungal agent towards the growth of wood decaying fungi of rubberwood. Schizohpyllum commune had reported to product schizophyllan during secondary metabolites, in which could possed antimicrobial activity. Batch solvent extraction using three solvent systems was carried out. After hydrodistillation process for 48 h, the results showed that 70% (v/v) methanol-water system provided the maximal extraction yield (41.47 %) for S. commune mycelia. The extracted antifungal agent had applied on the rubberwood block to investigate its effectiveness. The result found that the concentration at 5 μg/μl could inhibit the growth of white-rot fungi, in which was similar to that observed using minimum inhibitory concentration (MIC) assay previously.
