Sulfonation and anticoagulant activity of fungal exocellular β-(1→6)-d-glucan (lasiodiplodan)
(2013-02-15)
An exocellular β-(1→6)-d-glucan (lasiodiplodan) produced by a strain of Lasiodiplodia theobromae (MMLR) grown on sucrose was derivatized by sulfonation to promote anticoagulant activity. The structural features of the ...
Filamentous fungi from the Atlantic marine sponge Dragmacidon reticulatum
(2013-02-01)
Dragmacidon reticulatum is a marine sponge of wide occurrence in the Eastern and Western Atlantic. Little is known about D. reticulatum fungal diversity. Filamentous fungi recovered from D. reticulatum were assessed in the ...
Benzopyrans from Curvularia sp., an endophytic fungus associated with Ocotea corymbosa (Lauraceae)
(2005-10-01)
An isolate of Curvularia sp. was obtained from the leaves of Ocotea corymbosa, a native plant of the Brazilian Cerrado. The ethyl acetate extract from culture of this fungus afforded two benzopyran derivatives: ...
Purification and characterization of two β-glucosidases from the thermophilic fungus Thermoascus aurantiacus
(2002-12-01)
β-Glucosidase from the fungus Thermoascus aurantiacus grown on semi-solid fermentation medium (using ground corncob as substrate) was partially purified in 5 steps-ultrafiltration, ethanol precipitation, gel filtration and ...

CYTOPLASMIC AND PLASMA-MEMBRANE ULTRASTRUCTURE OF PARACOCCIDIOIDES-BRASILIENSIS YEAST-PHASE CELLS AS REVEALED BY FREEZE-ETCHING
(Cambridge University Press, 1990-12-01)
Using a freeze-etch technique the cytoplasmic and plasma membrane ultrastructure of Paracoccidiodies brasiliensis yeast-phase cells was studied. The multinucleate yeast-phase cells which grow by simultaneous multiple ...
Candida bromeliacearum sp nov and Candida ubatubensis sp nov., two yeast species isolated from the water tanks of Canistropsis seidelii (Bromeliaceae)
(Soc General Microbiology, 2005-09-01)
Strains belonging to two novel yeast species, Candida bromeliacearum and Candida ubatubensis, were isolated from the bromeliad tank of Canistropsis seidelii (Bromeliaceae) in a sandy coastal plain (restinga) ecosystem site ...
Modelling the lethargic crab disease.
(2009-01-01)
The lethargic crab disease (LCD) is an emergent infirmity that has decimated native populations of the mangrove land crab (Ucides cordatus, Decapoda: Ocypodidae) along the Brazilian coast. Several potential etiological ...
Purificação e caracterização de uma gentioexaose obtida de botriosferana por hidrólise ácida parcial
(Sociedade Brasileira de Química, 2008-01-01)
A hexa-oligosaccharide was obtained by partial acid hydrolysis from botryosphaeran, an exopolysaccharide (EPS) β(1→3; 1→6)-D-glucan type, produced by the ascomyceteous fungus Botryosphaeria rhodina. The oligosaccharide was ...
Paracoccidioides brasiliensis: phylogenetic and ecological aspects
(Springer, 2008-04-01)
The knowledge on the biological aspects of Paracoccidioides brasiliensis has evolved greatly since the first description of the disease in 1908. From the pioneers, who were able to clearly demonstrate the fungal nature of ...
