1. Resistance of acetylated Jacaranda copaia wood to termites and decaying fungi attack
RESUMO A durabilidade natural da madeira é essencial para a definição de seu uso, e essa propriedade pode ser potencializada com o tratamento químico adequado da madeira. Assim, o objetivo deste trabalho foi avaliar a resistência da madeira de Jacaranda copaia modificada quimicamente por acetilação a cupins e fungos apodrecedores. Cinco tratamentos ex

2. BEHAVIOR OF THERMALLY MODIFIED WOOD TO BIODETERIORATION BY XYLOPHAGE FUNGI
ABSTRACT Thermally modified wood undergoes chemical, physical, and mechanical modifications, resulting in changes in resistance to wood biodegrading agents. The objective of this study was to evaluate the resistance to biodeterioration of thermally modified wood by the industrial process VAP HolzSysteme® of Eucalyptus grandis, Pinus taeda and Tectona grandi

3. Programa de secagem para a madeira de seringueira (Hevea brasiliensis Muell. Arg.)
Resumo A seringueira (Hevea brasiliensis Muell. Arg.) tem sido cultivada para extração de látex e utilizada para produção de madeira ao fim do ciclo produtivo do látex. A secagem é uma etapa fundamental no processamento mecânico da madeira. No caso da madeira de seringueira, faz-se particularmente necessária a secagem artificial em estufa para a sua

4. Wood-decay fungi (Agaricomycetes, Basidiomycota) in three physiognomies in the Savannah region in Brazil
RESUMO Este estudo foi realizado visando Cerrado do Brasil). Visando entender se há correlações entre fisionomia e diversidade da vegetação (disponibilidade de substratos), grau de preservação, história de manejo da área e a proximidade de cursos de água com a diversidade de fungos decompositores de madeira. 796 espécimes foram coletados em quatro

5. Deterioration of Teak Wood in Accelerated Decay Test
ABSTRACT The present study aimed to evaluate the biological resistance of teak (Tectona grandis) heartwood and sapwood to the action of Trametes versicolor and Gloeophyllum trabeum fungi in laboratory accelerated decay assays. The mass loss evaluation of the samples was performed periodically. The heartwood presented a higher percentage of extractives and th

6. Alternative vibro-dynamic compression processing of wood-cement composites using Amazonian wood
RESUMO Compósito madeira-cimento é um potencial material de construção para regiões tropicais, devido a suas propriedades físico-mecânicas e resistência ao ataque de fungos e podridão. Contudo, é importante testar métodos alternativos de produção e madeiras que sejam mais simples e baratos do que os tradicionalmente usados, para que se alcance u

7. Natural Wood Resistance of Mimosa caesalpiniifolia in Field Testing
ABSTRACT The natural wood resistance of sabiá (Mimosa caesalpiniifolia) was evaluated under field conditions for use in organic agriculture. A total of 97 one-meter length logs with bark and diameter classes (5.0-7.9 and 8.0-11 cm) were fixed (0.4 m) in the soil at a distance of 0.5 m from the edges of a forest fragment in Viana, Espírito Santo, Brazil and

8. Natural decomposition of hornbeam wood decayed by the white rot fungus Trametes versicolor
ABSTRACT The impacts of white-rot fungi on altering wood chemistry have been studied mostly in vitro. However, in vivo approaches may enable better assessment of the nature of interactions between saprotrophic fungi and host tree in nature. Hence, decayed and sound wood samples were collected from a naturally infected tree (Carpinus betulus L.). Fruiting bod

9. Host-exclusivity and host-recurrence by wood decay fungi (Basidiomycota - Agaricomycetes) in Brazilian mangroves
ABSTRACT This study aimed to investigate for the first time the ecological interactions between species of Agaricomycetes and their host plants in Brazilian mangroves. Thirty-two field trips were undertaken to four mangroves in the state of Pernambuco, Brazil, from April 2009 to March 2010. One 250 x 40 m stand was delimited in each mangrove and six categori

10. Wood-associated fungi produce volatile organic compounds toxic to root-knot nematode
ABSTRACT Since volatiles do not leave residues in food and cause low toxicity to humans, they can act as a skeleton for new nematicidal molecules, once they have demonstrated activity against phytonematodes. The aim of this study was to evaluate the effect of volatile organic compounds (VOCs) released by wood-associated fungi on controling second-stage juven

11. Hydroxylation of 1,8-cineole by Mucor ramannianusand Aspergillus niger
The monoterpenoid 1,8-cineole is obtained from the leaves of Eucalyptus globulus and it has important biological activities. It is a cheap natural substrate because it is a by-product of the Eucalyptuscultivation for wood and pulp production. In this study, it was evaluated the potential of three filamentous fungi in the biotransformation of 1,8-cineole. The

12. On the use of capsaicin as a natural preservative against fungal attack on Pinus sp. and Hymenaea sp. woods
Capsaicin (capsicum oleoresin) extracted from two peeper species, Capsicum frutescens and Capsicum baccatum, was investigated as a natural preservative against fungal (Paecilomyces variotti) attack on Pinus sp. and Hymenaea sp. Static contact angle measurements were performed as a function of time in order to investigate the wetting properties of the wood sa
