| ABSTRACT Twenty-seven Tritirachium strains were present in the URM culture collection originally founded in Brazil by Augusto Chaves Batista. Fifteen freshly-prepared cultures were obtained from these original strains preserved under mineral oil. DNA was extracted for analysing phylogenetic relationships using the sequence information available from Tritirachium type materials and reference strains. Phylogenetic analysis using the internal transcribed spacer (ITS) ribosomal DNA sequences revealed that eight of these strains belong to the same clade as of T. oryzae and that the four other strains belong to the same clade as of T. candoliense. The strain URM 38, which was previously identified as “T. brumptii”, appeared to exist as a single lineage, related... |

| ABSTRACT We studied the fungal endophyte community of the leaves of Myracrodruon urundeuva in Brazil along with their potential to produce L-asparaginase. In total, 187 endophytes were isolated. The colonization rate of leaf fragments from caatinga (10.41 %) was lower than those from brejo de altitude (39.58 %). Sequences of ITS rDNA from all endophytes revealed relationships with Ascomycota (Botryosphaeriales, Chaetothyriales, Diaporthales, Eurotiales, Glomerellales, Hypocreales, and Pleosporales) and Basidiomycota (Polyporales). The most frequent endophytes were members of the genus Diaporthe. Talaromyces was an indicator genus for caatinga while Phyllosticta, Diaporthe, and Colletotrichum were for brejo de altitude. The composition of endophytic fungi... |

| ABSTRACT Here, Quambalaria fabacearum and Neopestalotiopsis brasiliensis are introduced as new species from Brazil, isolated as endophyte from Mimosa tenuiflora and causing post-harvest rot disease on fruits of Psidium guajava, respectively. Diaporthe inconspicua is emended to include a more detailed morphological description. Neopestalotiopsis egyptiaca is reported as new to the Americas and as causing post-harvest rot disease on fruits of Psidium guajava, while Umbelopsis isabellina is reported as endophyte. |

| A presença de metais pesados no solo proporciona impacto sobre os microrganismos, vegetação e os processos funcionais do ecossistema. Visando comprovar que Mucorales são afetados pela extração de cobre na Mineradora Caraíba, Jaguarari, BA, espécies de Mucorales foram isoladas de amostras de solo coletadas nas épocas seca e chuvosa. Os Mucorales foram identificados e caracterizados quanto à capacidade de degradar amido e inulina. Utilizando os métodos de diluição e placa de solo, foram obtidos 46 isolados de Mucorales pertencentes a sete diferentes espécies. Absidia blakesleeana Lendner, A. cylindrospora Hagem, A. hialospora (Saito) Lendn., Cunninghamella elegans Lendner, Rhizopus microsporus V. Thieghen, R. oryzae Went. & Prinsen Geerl. e... |

| ABSTRACT A literature-based checklist of species of Aspergillus, Penicillium, and Talaromyces recorded in the Brazilian tropical dry forest (Caatinga), the largest tropical dry forest region in South America, is provided. A total of 130 species (60 Aspergillus, 57 Penicillium, and 13 Talaromyces) are reported. Soil was the most common substrate, with 122 species records. Various reported species are well known in biotechnological processes. This checklist reflects the limited knowledge of fungal species in tropical dry environments. These data provide a good starting point for biogeographical studies on species of Aspergillus, Penicillium, and Talaromyces in dry environments worldwide. In addition, the new species Penicillium vascosobrinhous is introduced,... |

| This work aimed at the assessment of fermentative capacity of original diploid, monocellular haploid and recuperated diploid cultures of S. cerevisiae in sterilized sugar-cane wort. Twenty eight cultures were analyzed, four being original diploids (URM-4420, Itaiquara Ferment FIT, Lallemand Ferment FLA and Wild Ferment SEL); 12 monocellular haploids from original ones and 12 recuperated diploids from the monocells. The ethanol percentage ranged from 1.7 to 6.2% and the unfermentable reducing sugars from 0.45 to 0.50g/100mL. The highest ethanol percentages were produced by the monocellular cultures URM-MH3 (4.8%) in 12 h and SEL-MH1 (6.2%) in 24 h, corresponding to the productivity values of 3.15 and 2.03 g.L-1.h-1, respectively. The recuperated diploids... |

| Abstract Protein hydrolysates originating from egg white have already been reported to be bioactive and, among their biological activities, possess the antioxidant property that protects the body from early ageing and diseases linked to oxidation. Therefore, the objective of this work was to evaluate the antioxidant activity of hydrolysates obtained by the hydrolysis of egg white from hen poultry. The protease produced by Aspergillus avenaceus URM 6706 was purified and subsequently applied to hydrolysate the egg white, and the degree of hydrolysis was verified during the protease exposure time (4-24 h). The hydrolysis was intensified over time of exposure to the protease. It was possible to detect the antioxidant activities of eliminating the... |

| This study investigated the ocurrence of Malassezia species in clinically healthy students and with macules with a slight fawn discoloration and characterized the isolates as to the pathogenicity factors such as growth at 37ºC, lipase, phospholipase and protease detection. Clinical samples were collected from different body sites of one hundred students of different ages and both sexes. The samples, obtained by scrapping the skin surface and the scalp, were treated with potassa and cultured. Cultures were obtained in Petri dishes containing Sabouraud agar medium added of olive oil, incubated at room temperature and at 37ºC. Culture identifications were based in their morphological and physiological properties. Lipase, phospholipase and protease detection... |
