Sliced bamboo veneer used as a high-end decoration material is a highly innovative material for the deep processing of bamboo. However, bamboo is rich in starch and small molecular soluble sugars, making it susceptible to mildew infection and limiting the wide application of sliced veneer plybamboo. Spice essential oils are considered green and safe antimildew agents, which are cheap and accessible. The natural phenolic substances in plant essential oil have a good inhibitory effect on bamboo mildew. In this study, three types of spice essential oils (clove essential oil, oregano essential oil, and fennel essential oil) were employed, and their antifungal activity against bamboo mildews was assessed using the Oxford cup method, scanning electron microscopy, transmission electron microscopy, and a micro pH meter. The results demonstrated that the diameters of the Inhibition Zone against four common bamboo mildews (AN TV PC, ; MM, Mixed Mildews) caused by clove essential oil were 25.68 mm, 23.22 mm, 30.68 mm, and 25.43 mm, respectively. As an explanation, clove essential oil can inhibit or eliminate mildew by damaging and disrupting the cell membrane of the bamboo mildew, leading to significant shrinkage, distortion, surface roughness, formation of holes, or partial structural cracks in the mildew's mycelium. Additionally, it may interfere with and disrupt the pH balance of the intracellular and extracellular fluids within the cell. Furthermore, we also report that sliced veneer plybamboo impregnated with clove essential oil on each layer showed fine inhibition rates of 50%, 75%, 100%, and 25% against AN, TV, PC, and MM, respectively. This research underscores a sustainable approach to mildew prevention, crucial for advancing bamboo's utilization in high-value furniture decor applications.
Mildew growth in sliced veneer plybamboo poses a significant challenge, particularly in its use for high-end furniture and decor. Traditionally, chemical treatments have been the primary solution though they often raise environmental concerns. Essential oils, with their well-documented antimicrobial properties, have emerged as an important natural and eco-friendly alternative for preventing mildew. These oils inhibit mildew growth effectively while offering a sustainable, non-toxic solution that reduces harm to both the environment and human health. By leveraging essential oils, it becomes possible to extend the lifespan of bamboo products, making them more durable and suitable for broader applications in furniture and decor, all while addressing the ecological limitations of conventional mildew prevention methods.
竹切片单板作为一种高端装饰材料，是竹材深加工的创新性材料。然而，竹子富含淀粉和小分子可溶性糖，容易受到霉菌感染，限制了竹切片单板的广泛应用。香料精油被认为是绿色和安全的防霉剂，价格低廉，容易获得。植物精油中的天然酚类物质对竹霉菌有很好的抑制作用。本研究采用 3 种香料精油（丁香精油、牛至精油、茴香精油），采用牛津杯法、扫描电子显微镜、透射电子显微镜和微 pH 计评价其对竹霉菌的抑菌活性。结果表明，丁香精油对 4 种常见竹霉菌（AN TV PC，； MM，混合霉菌）的抑菌圈直径分别为 25.68mm、23.22mm、30.68mm 和 25.43mm。这可以解释为丁香精油通过破坏和扰乱竹霉菌的细胞膜来抑制或消除霉菌，导致霉菌菌丝明显收缩、变形、表面粗糙、形成孔或部分结构裂纹。此外，它可能会干扰和破坏细胞内外液的 pH 平衡。此外，我们还报告称，每层浸渍丁香精油的竹切片单板对 AN、TV、PC 和 MM 的抑制率分别为 50%、75%、100%和 25%。这项研究强调了一种可持续的防霉方法，对于推进竹材在高价值家具装饰应用中的应用至关重要。
竹切片单板中的霉菌生长是一个重大挑战，尤其是在其用于高端家具和装饰方面。传统上，化学处理一直是主要的解决方案，但它们往往会引起环境问题。精油以其经过充分记录的抗菌特性而成为一种重要的天然和环保替代品，可有效防止霉菌生长。这些油在提供可持续、无毒的解决方案的同时，减少对环境和人类健康的危害，有效地抑制霉菌生长。通过利用精油，可以延长竹制品的使用寿命，使它们更耐用，更适合家具和装饰的广泛应用，同时解决传统防霉方法的生态限制。
