The new phenalenone metabolites 1, 2, 4, and 6 were isolated from the marine-derived endophytic fungus Coniothyrium cereale, in addition to the ergostane-type sterol (3) and entatrovenetinone (5). Compounds 1 and 2 represent two unusual nitrogen-containing compounds, which are composed of a sterol portion condensed via two bonds to phenalenone derivatives. Compound 6, which contains unprecedent...

To assess the impacts of Cu and Zn on fungi, we tested the growth of 18 taxonomically different saprotrophic (basidiomycete, ascomycete and zygomycete) fungi and their production of extracellular oxidative enzymes on Cu(0, 100, 200, 400 mg kg–1) or Zn(0, 100, 200, 400 mg kg–1) containing ABTS (2,2 ́-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) agar plates. Coniothyrium sp. was the most toler...

Three aviculariine genera endemic to Brazil are revised. Typhochlaena C. L. Koch, 1850 is resurrected, including five species; Pachistopelma Pocock, 1901 includes two species; and Iridopelma Pocock, 1901, six species. Nine species are newly described: Typhochlaena ammasp. n., Typhochlaena costaesp. n., Typhochlaena curumimsp. n., Typhochlaena paschoalisp. n., Pachistopelma bromelicolasp. n., Ir...

O presente estudo teve por objetivo realizar a identificação dos fungos encontrados na própolis produzido Apis mellifera L. da Baía do Iguape, Brasil. Para tanto, foram utilizadas técnicas morfológicas, bioquímicas e moleculares, sendo averiguado o perfil de restrição gerado espaçador interno transcrito (ITS1 ITS4). tamanho produtos PCR foi analisado quanto ao obtidos com endonuclease (HhaI, Ha...
