The wood preservation industry has depended on toxicity as a mechanism of effectiveness against decay fungi to extend the life of wood used in adverse conditions. An alternative to toxicity, however, is to study and understand the mechanism of fungal attack and stop it before it can start. Knowing that fungi need moisture for colonization, a new approach to wood preservation is to lower the cell wall moisture content below that needed for fungal attack. Acetylation chemistry is known to reduce the moisture content in the cell wall, and it was used to study moisture levels in the bulk cell wall and in the isolated cell wall polymers. Resistance to brown-rot was determined using a 12-week soil block test with . Weight loss was measured and an analysis of what was lost was determined.
木材防腐行业一直依赖毒性作为对抗腐朽真菌的有效机制，以延长在恶劣条件下使用的木材的使用寿命。然而，毒性的替代方法是研究和了解真菌侵袭的机制，并在其开始之前加以阻止。由于已知真菌定殖需要水分，木材防腐的一种新方法是将细胞壁水分含量降低到真菌侵袭所需水平以下。已知乙酰化化学可降低细胞壁中的水分含量，并用于研究整体细胞壁和分离的细胞壁聚合物中的水分水平。使用为期12周的土壤块试验，测定了对褐腐病的抗性。测量了重量损失，并对损失的物质进行了分析。
