Antifungal γ-Pyrone and Isoprenylated Cyclohexanoids from the Fungus Beenakia informis.

Chemical investigation of the extract of the macroscopic fungus Beenakia informis led to the isolation of a previously unreported γ-pyrone and two new isoprenylated cyclohexanoids, together with speciocin N. Their structures were elucidated spectroscopically and the absolute configuration was determined by comparison of the experimental vs. calculated ECD curves.

Solid-state bioprocessing of sugarcane bagasse with for phenolic compounds extraction.

Sugarcane bagasse is a natural source of phenolic compounds. However, these compounds are bound to lignocellulose components, reducing their ability to function as good antioxidants. These linkages are hydrolyzed by enzymes like -glucosidases, increasing free phenolics.

Lanostanoid triterpenes from the fungus .

Five new lanostanoid triterpenes were isolated from the extract of . Three of the metabolites () present a Δ skeleton with an uncommon keto functionality at C-1. Another compound () has an unprecedented rearranged skeleton in which methyl-19 was transposed to C-1, with conjugated double bonds at Δ and Δ.

Biodiversity and threats in non-protected areas: A multidisciplinary and multi-taxa approach focused on the Atlantic Forest.

Along many decades, protected environments were targeted by the scientific community for ecological research and for the collection of scientific information related to environmental aspects and biodiversity. However, most of the territory in hotspot regions with weak or even non legal protection has been left aside. These non-protected areas (NPA) could host high biodiversity values.

Influence of light on lignin-degrading activities of fungal genus Polyporus s. str.

Six strains belonging to five species of Polyporus (P. arcularius, P. arcularioides, P.

Decrypting the Polyporus dictyopus complex: Recovery of Atroporus Ryvarden and segregation of Neodictyopus gen. nov. (Polyporales, Basidiomyocta).

Polyporus dictyopus, with a large number of heterotypic synonyms, has been traditionally considered a species complex, characterized by wide morphological variation and geographic distribution. Thus, neotropical specimens previously identified as P. dictyopus from Amazonia, Cerrado and Atlantic Forest biomes were studied based on detailed macro- and micromorphological examination and phylogenetic analyses, using distinct ribosomal and protein-coding genomic regions: the nuclear ribosomal internal transcribed spacer (nrITS), nuclear ribosomal large subunit (nrLSU), and RNA polymerase II second subunit (RPB2).

Grape stalks as substrate for white rot fungi, lignocellulolytic enzyme production and dye decolorization.

The aim of this work was to evaluate the potential of grape stalks, an agroindustrial waste, for growth and lignocellulolytic enzyme production via solid-state fermentation, using the following three white rot fungi: Trametes trogii, Stereum hirsutum and Coriolus antarcticus. The decolorization of several dyes by the above mentioned cultures was also investigated. Similar values of dry weight loss of the substrate were measured after 60 days (33-43 %).
