Fermentation capacity of Saccharomyces cerevisiae cultures BABT
Alencar,Elvira Maria Bezerra de; Souza-Motta,Cristina Maria de; Walter,Bruno Souza; Santos,Rejane Maria Pessoa; Marques,Olga Martins; Queiroz,Lusinete Aciole de.
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...

Fusarium lateritium (NEES) as an agent of fungemia in a patient infected with the human immunodeficiency virus (HIV) BJM
Cambuim,Idalina Inês Fonsêca Nogueira; Neves,Rejane Pereira; Queiroz,Lusinete Aciole de; Magalhães,Oliane Maria Correia; Lima,Débora Maria Massa.
Emerging fungal pathogens are associated with significant morbidity and mortality in the immunocompromised host. The association of fungi from the Fusarium genus with human infection in uncommon. The objective of this paper is to report the first case of fungaemia caused by Fusarium lateritium in a 42-year-old HIV-infected patient.

Identification and pathogenicity of Malassezia species isolated from human healthy skin and with macules BJM
Neves,Rejane Pereira; Magalhães,Oliane Maria Correia; Silva,Merivânia Lucas da; Souza-Motta,Cristina Maria de; Queiroz,Lusinete Aciole de.
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...

Occorrence of Pseudomicrodochium suttonii in Brazil Rev. Microbiol.
Nunes,Amanda Torres; Cavalcanti,Maria Auxiliadora de Q.; Queiroz,Lusinete Aciole de.
Pseudomicrodochium suttonii was isolated from the soil of Derby Square, a leisure area in Recife city, Pernambuco, Brazil. For the isolation, suspensions were made in distilled sterile water. According to the literature, this is probably the first occurrence reported in South America.

Pathogenic aspects of Epidermophyton floccosum langeron et milochevitch as possible aethiological agent of Tinea capits BJM
Macêdo,Danielle Patrícia Cerqueira; Neves,Rejane Pereira; Magalhães,Oliane Maria Correia; Souza-Motta,Cristina Maria de; Queiroz,Lusinete Aciole de.
The aim of this research was to verify the ability of 15 isolates of Epidermophyton floccosum to perforate hair in vitro and characterize them for pathogenicity factors such as growth at 37ºC and proteinase and phospholipase production. Fourteen isolates perforated hair and from these twelve produced perforating organs. All isolates grew at 37ºC and produced proteinase, but not phospholipase. These results suggest that E. floccosum may be a possible aethiological agent of tinea capitis.
