The aim of this study was to characterize the properties of juvenile and mature heartwood of Robinia pseudoacacia L. (black locust). The content, the composition, and subcellular localization of heartwood extractives were studied in 14 old-grown trees from forest sites in Germany and Hungary, as well as in 16 younger trees of four clone types. Heartwood extractives (methanol and acetone extract...

The Atlas cedar, Cedrus atlantica is a resinous species of Pinaceae originated from North Africa and well known for its noble timber. This work was conducted to assess the natural durability of its wood, to study the chemical composition of essential oil extracted from its sawdust wood and to test the bioactivity of this essential oil against four wood decaying fungi: Gloeophyllum trabeum, Olig...

Three commercial silicone emulsions with different functional groups i.e., quat-silicone micro-emulsion (<40 nm particle size), amino-silicone macro-emulsion (110 nm), and silicone macro-emulsion with alkylmodified side groups (740 nm) were used to protect wood samples against fungal decay. The addition of the emulsions to an agar growth medium revealed that all three silicone formulations inhi...

Abstract Pressurized hot water extraction (HWE) treatment has the benefit of simultaneous hemicellulose-based carbohydrates and modification solid phase, but it does not drastically improve wood durability. However, removing hemicelluloses from by HWE creates water-filled spaces in cell walls which could be filled with agent order to properties wood. Without drying, can added into saturated via...

Sugarcane Bagasse (SCB) has some characteristics that hinder its direct use as fuel. Torrefaction pre-treatment could be considered to improve the SCB properties for an energy and reduce impact of storage on reduction these properties. were torrefied at 290 °C in a screw reactor, during 5, 7.5 10 min. Then, raw samples exposed successively water-leaching white brown rot fungi, emulate condition...

Dünya nüfusunda meydana gelen artışa bağlı olarak orman ürünlerinin kullanımı yaygınlaşmıştır. Ancak, artan ürünleri ihtiyacını ekosistemi tehlikeye sokmadan karşılamak dikkat edilmesi gereken en önemli husus olmaktadır. Bu bakımdan ormanlardan elde edilen ağaç malzemelerin kullanım sürelerinin arttırılması araştırmacıların ilgi duyduğu konular arasında yer almaktadır. çalışma ile ülkemizde doğ...

Abstract The order Boletales is a group of fungi with complex life styles, which include saprophytic and ectomycorrhizal mushroom-forming fungi. In the present study, complete mitogenomes two species, Coniophora olivacea, C. puteana, were assembled compared Boletales. Both comprised circular DNA molecules sizes 78,350 bp 79,655 bp, respectively. Comparative mitogenomic analysis indicated that s...
