| 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... |

| 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... |
