The spruce is the one of the refractory wood species. In this study, the spruce sapwood samples were treated with enzymes to improve its permeability. The pit membranes play an important role for water transporting between the adjacent cells. The spruce wood pit membranes are prone to close under the fiber saturated point. As a result of the liquid transportation is blocked, the impregnation process is getting difficult. The wood pits compose of cellulose, hemicellulose, lignin, pectin, and phenolic components. The torus surface is covered with pectin. Bioprep 3000 L, Viscozyme L, Texazym BFE, Texazym DLG are commonly used in the textile industry to remove lignocellulosic materials. It was aimed to destroy the closed pits via enzymatic treatment. At the end of the study, the retention and penetration increments were obtained after the enzymatic treatment. The wood samples treated with enzymes which are composed of enzymes mixtures gave more penetration and retention values.

Doğu ladini (Picea orientalis L.) geçirgenliği düşük olan ağaç türlerinden bir tanesidir. Bu çalışmada doğu ladini diri odun örnekleri enzimatik muameleye uğratılarak, geçirgenliği arttırılmaya çalışılmıştır. Geçit membranları, komşu hücreler arasındaki su iletiminin gerçekleştirilmesinde önemli bir rol üstlenmektedir. Doğu ladini geçitleri, lif doygunluk noktası altındaki rutubetlerde kapanmaya meyillidir. Bu durum odundaki sıvı iletimini engelleyerek, emprenye işlemini zorlaştırmaktadır. Geçitler selüloz, hemiselüloz, lignin, pektin ve fenolik bileşiklerden oluşmaktadır. Torusun yüzeyini pektin maddesi kaplamaktadır. Bioprep 3000 L, Viscozyme L, Texazym BFE, Texazym DLG enzimleri tekstil endüstrisinde, lignoselülozik materyalin uzaklaştırılmasında yaygın olarak kullanılan enzimlerdir. Enzimatik muamele ile kapalı geçitlerin yapısı tahrip edilerek açılması hedeflenmiştir. Çalışmanın sonucunda, enzimatik muamele ile ladin odununun retensiyon ve penetrasyon derinliği değerlerinde artışlar elde edilmiştir. Farklı karışımlarından oluşan enzimler ile muamele edilen örneklerin retensiyon ve penetrasyon değerlerinde daha fazla artış meydana gelmiştir.
