| identification, antifungal susceptibility and scanning electron microscopy of a keratinolytic strain of rhodotorula mucilaginosa: a primary causative agent of onychomycosis. | onychomycosis is a dermatological problem of high prevalence that mainly affects the hallux toenail. onychomycosis caused by the yeast rhodotorula mucilaginosa was identified using colony morphology, light microscopy, urease and carbohydrate metabolism in a 57-year-old immunocompetent patient from rio de janeiro, brazil. high-resolution scanning electron microscopy of nail fragments, processed by a noncoating method, led to the observation with fine detail of the structures of both nail and fung ... | 2009 | 19170752 |
| yeasts in the intertidal sediments of a polluted estuary in rio de janeiro, brazil. | yeasts were found concentrated at the sediment surface and with the highest counts at the most polluted site. candida krusei, pichia membranaefaciens and similar species typically forming rugose colonies with radiating ridges were the prevalent yeasts in these sediments, and species like rhodotorula rubra related to basidiomycetous fungi were found in relatively low numbers. | 1982 | 7092202 |
| yeasts associated with the white shrimp penaeus schmitti, sediment, and water of sepetiba bay, rio de janeiro, brasil. | samples were collected in a polluted site with mean fecal coliform counts of the water being 9.0 x 10(2)/100 ml and less polluted areas including commercial fishing areas with fecal coliforms typically below 2.0 x 10(1)/100 ml. yeast populations from the polluted site were 4.6 x 10(2) to 9.2 x 10(3)/g of shrimp intestine, 1.0 x 10(1) to 2.4 x 10(2)/g of sediment and 4.0 x 10(-1) to 4.6 x 10(1)/ml of water, and in the less polluted site 3.0 x 10(1) to 2.3 x 10(2)/g of intestines and 3.0 x 10(-1) ... | 1989 | 2750315 |
| yeast communities associated with sugarcane in campos, rio de janeiro, brazil. | yeast communities associated with sugarcane leaves, stems and rhizosphere during different phases of plant development were studied near campos, in rio de janeiro, brazil. atmospheric temperature, soil granulometry and ph, and sugar cane juice degree brix and ph were determined. yeast communities associated with sugarcane were obtained after cellular extraction by shaking, blending and shaking plus sonication, and cultured on yeast nitrogen base agar plus glucose (0.5%) and yeast extract-malt ex ... | 1998 | 10943361 |
| taxonomic implications of rhodotorula rubra isolates from polluted sea water in rio de janeiro, brazil. | sixty two strains of rhodotorula rubra which were all isolated from marine and estuarine waters of rio de janeiro were found variable for 19 to 32 carbon assimilation tests used in yeast taxonomy. two r. rubra strains which had latent assimilation of maltose and melizitose appeared to be intermediate with r. pilimanae. strains of r. glutinis var dairenensis which differed from r. rubra only by weak assimilation of nitrate appeared to be intermediated between these two species. our physiological ... | 1979 | 572568 |
