1. 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

2. Decolorization of remazol brilliant blue R with laccase from Lentinus crinitus grown in agro-industrial by-products
ABSTRACT Lentinus crinitus is a white-rot fungus that produces laccase, an enzyme used for dye decolorization. Enzyme production depends on cultivation conditions, mainly agro-industrial by-products. We aimed to produce laccase from Lentinus crinitus with agro-industrial by-products for dye decolorization. Culture medium had coffee husk (CH) or citric pulp p

3. 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

4. Tannic extract potential as natural wood preservative of Acacia mearnsii
ABSTRACT High toxicity of the preservatives most frequently used in wood treatment and the resulting risks of handling pose a threat to small producers and to the environment. In an attempt to mitigate these problems, the present study was conducted with the objective of evaluating the preservative effect of tannic extract on biodeterioration of Acacia mearn

5. In vitro free radicals scavenging activity and antioxidant capacity of solid-state fermented wheat bran and its potential modulation of antioxidative molecular targets in chicken PBMC
ABSTRACT The purpose of this study was to demonstrate the in vitro free radical scavenging activity and antioxidant capacity in solid-state fermented wheat bran and its potential modulation of antioxidative molecular targets in chicken peripheral blood mononuclear cells (PBMC). After solid-state fermentation of wheat bran by white rot fungi for 12 d, the sca

6. Preliminary studies of new strains of Trametes sp. from Argentina for laccase production ability
Abstract Oxidative enzymes secreted by white rot fungi can be applied in several technological processes within the paper industry, biofuel production and bioremediation. The discovery of native strains from the biodiverse Misiones (Argentina) forest can provide useful enzymes for biotechnological purposes. In this work, we evaluated the laccase and manganes

7. Hardness, Decay and Water Resistance of Polypropylene/Montmorillonite/Almond Shell Flour Composites
The effect of montmorillonite (MMT) loading (0, 2.5, and 5 wt%) and almond shell flour (ASF) content (30, 35, and 40 wt%) on the decay resistance, hardness, water resistance of injection molded polypropylene (PP) composites was investigated. The amount of maleic anhydride grafted polypropylene was kept constant at 2% for all formulations. White-rot (Trametes

8. Aflatoxin detoxification by manganese peroxidase purified from Pleurotus ostreatus
Manganese peroxidase (MnP) was produced from white rot edible mushroom Pleurotus ostreatus on the culture filtrate. The enzyme was purified to homogeneity using (NH4)2SO4 precipitation, DEAE-Sepharose and Sephadex G-100 column chromatography. The final enzyme activity achieved 81UmL-1, specific activity 78 U mg-1 with purification fold of 130 and recovery 1.

9. Doenças quiescentes em goiabas: quantificação e controle pós-colheita / Quiescent diseases in guava: quantification and post-harvest control
Post-harvest diseases in guavas may represent damages from 20 to 40%. Environmental conditions and disease management, before or after harvesting, are among their major causes. Standards proposed by the Integrated Production Fruit (IPF) ensure fruit quality and sustainable production with rational use of agrochemicals. Using the white-fleshed variety Kumagai

10. Evidence that the Ceratobasidium-like white-thread blight and black rot fungal pathogens from persimmon and tea crops in the Brazilian Atlantic Forest agroecosystem are two distinct phylospecies
The white-thread blight and black rot (WTBR) caused by basidiomycetous fungi of the genus Ceratobasidium is emerging as an important plant disease in Brazil, particularly for crop species in the Ericales such as persimmon (Diospyros kaki) and tea (Camellia sinensis). However, the species identity of the fungal pathogen associated with either of these hosts i

11. Sobrevivência de escleródios de Sclerotinia sclerotiorum em solo, com aplicação de Clonostachys rosea / Survival of sclerotia of Sclerotinia sclerotiorum in the soil, with application of Clonostachys rosea
Sclerotinia sclerotiorum causes white mold, stem rot, watery rot and white rot disease in many important crops such as bean, soybean, cotton, tomato, and pea. The pathogen produces sclerotia that can survive in the field for several years, which hinders white mold control. In the perspective of assessing biocontrol in the management of the disease, we tested

12. ASPECTOS DO CONTROLE BIOLÓGICO DE Botrytis cinerea Pers. Ex. Fr. EM VIDEIRA / ASPECTS OF Botrytis cinerea Pers. Ex. Fr. BIOLOGICAL CONTROL ON GRAPEVINE
Rio Grande do Sul (RS), the most important state of grape production in Brazil, harvests, approximately, 780 thousand tons annually. One of the biggest constraint factors to the obtainment of higher production numbers is the incidence of late season diseases in vineyards, being botrytis bunch rot, caused by Botrytis cinerea, one of the major contributors for
