1. Biodeterioração, anatomia do lenho e análise de risco de queda de árvores de tipuana, Tipuana tipu (Benth.) O. Kuntze, nos passeios públicos da cidade de São Paulo, SP / Biodeterioration, wood anatomy and falling risk analysis of tipuana, Tipuana tipu (Benth.). O. Kuntze trees, in the sidewalks of São Paulo city, SP
Os objetivos do presente trabalho foram: avaliar o processo de biodeterioração do lenho das árvores de tipuana na cidade de São Paulo e relacionar as alterações da sua estrutura anatômica e propriedades físico-mecânicas com o seu risco de queda. Nos passeios públicos de regiões selecionadas da cidade, 1109 árvores de tipuana foram caracterizadas

2. Efeito inibitÃrio de Ãleos essenciais de citros sobre o crescimento de microrganismos. / Inhibitory effect of essential oils of citros on the growth of microorganisms.
The current trend adopted by the lawmaking agencies of food production and consumers has demanded a progressive removal of chemical additives in food production. The essential oils found in medicinal, aromatic and seasoning plants have interested to the food industries as an alternative to synthetic additives. Essential oils present an antimicrobial activity

3. Degradation of Wood Preservatives by Fungi
Wood-inhabiting fungi, not necessarily responsible for major decay, are shown to be capable of degrading a toxic compound into a less potent form, thus rendering it less effective in protecting wood from decay by less-tolerant basidiomycetous wood-destroyers. Sweetgum or pine sapwood blocks treated with preservatives (ammoniacal copper arsenate, fluor-chrome

4. Equine zygomycosis caused by Conidiobolus lamprauges.
A 15-year-old Arabian mare from southern Louisiana with a 2-month history of periodic epistaxis and severe weight loss had a large, fibrosing, granulomatous mass containing numerous nodules ("kunkers") projecting dorsally into the nasopharynx, and was euthanized at the owner's request. In addition to these kunkers, the mass contained a single trematode tenta

5. Biochemical and Molecular Characterization of a Laccase from Marasmius quercophilus
The basidiomycete Marasmius quercophilus is commonly found during autumn on the decaying litter of the evergreen oak (Quercus ilex L.), a plant characteristic of Mediterranean forest. This white-rot fungus colonizes the leaf surface with rhizomorphs, causing a total bleaching of the leaf. In synthetic liquid media, this white-rot fungus has strong laccase ac

6. Rapid and Pervasive Occupation of Fallen Mangrove Leaves by a Marine Zoosporic Fungus †
Samples of leaves of red mangrove (Rhizophora mangle) were incubated on an agar medium selective for pythiaceous oomycetes. Leaves on trees above the water did not contain oomycetes. Marine oomycetes, principally Phytophthora vesicula, had colonized leaves within 2 h of leaf submergence, probably finding them by chemotaxis. The frequency of occurrence of P.

7. Clonal Reproduction and Limited Dispersal in an Environmental Population of Cryptococcus neoformans var. gattii Isolates from Australia
Cryptococcus neoformans var. gattii is a causative agent of cryptococcosis and is thought to have a specific ecological association with a number of Eucalyptus species in Australia. However, the role that the tree plays in the life cycle of the fungus and the nature of the infectious propagule are not well understood. This study set out to examine whether se

8. Lignin-Modifying Enzymes of Flavodon flavus, a Basidiomycete Isolated from a Coastal Marine Environment†
A basidiomycetous fungus Flavodon flavus (Klotzsch) Ryvarden (strain 312), isolated from decaying sea grass from a coral lagoon off the west coast of India, mineralized nearly 24% of 14C-labeled synthetic lignin to 14CO2 in 24 days. When grown in low-nitrogen medium (2.4 mM N) this fungus produced three major classes of extracellular lignin-modifying enzymes

9. PCR Assays That Identify the Grapevine Dieback Fungus Eutypa lata
Eutypa lata is the causal fungal agent of Eutypa dieback, a serious grapevine necrotic disease. The erratic and delayed (1 to 2 months) appearance of characteristic conidia on culture media and the presence of numerous microorganisms in decaying wood make it difficult either to identify or to detect E. lata in grapevine wood samples. We designed six pairs of

10. Inhibition of the alveolar macrophage oxidative burst by a diffusible component from the surface of the spores of the fungus Aspergillus fumigatus.
BACKGROUND: Aspergillus fumigatus is a fungus that grows on dead and decaying organic matter in the environment and whose spores are present ubiquitously in the air. The fungus causes a range of diseases in the human lung. A study was undertaken to demonstrate and partially characterise an inhibitor of the macrophage respiratory burst from the surface of A f

11. Palo Podrido: Model for Extensive Delignification of Wood by Ganoderma applanatum
Chemical and micromorphological analysis revealed that South Chilean “palo podrido” results from a white-rot fungus that causes highly selective and extensive delignification. Palo podrido samples from 10 different hardwood trunks (Eucryphia cordifolia, Drimys winteri, and Nothofagus dombeyi) decayed by Ganoderma applanatum were analyzed. Of 14 samples,
