Description
Summary:Abstract Wood and wood-based materials are commonly used for storage, but their surfaces are prone to biodegradation by microorganisms, especially fungi. This study focuses on the microbial communities on pine wood storage boxes treated with an anti-termite and mold solution in a tropical region in Dong Nai, Vietnam. We isolated 13 fungal strains from these surfaces and classified them into six genera: Rhizopus, Aspergillus, Fusarium, Curvularia, Penicillium, and Trichoderma. Enzyme activity tests revealed that strains Curvularia eragrostidis TD4.2 and Aspergillus sydowii TD5 were the most effective producers of cellulase, amylase, and laccase. Shotgun metagenomics analysis of the biological sample of the discolored surface of pine storage boxes indicated that Ascomycota was the dominant phylum, with Dothideomycetes and Sordariomycetes as the prevalent class. Aureobasidium (0.33%) and Chaetomium (1.1%) were the most abundant genera in the Dothideomycetes and Sordariomycetes, respectively. This research illustrates the complexity of microbial communities on wood surfaces, providing insights into the fungal dynamics affecting wooden storage materials in tropical climates.
