We studied the dynamic behavior of wild yeasts during spontaneous wine fermentation at a winery in the Valais region of Switzerland. Wild yeasts in the winery environment were characterized using a PCR-RFLP method. Up to 11 different yeast species were isolated from the vineyard air, whereas only seven were recovered from the grapes surface. We initially investigated a cultureindependent method...
We present a case of postoperative infection which presented as nonunion fracture femur in a 30-year-old man due to Rhodotorula mucilaginosa. This is the first report of Rhodotorula infection in a patient with fracture nonunion. The patient underwent repeated surgical debridement and received intensive antibiotic therapy before the diagnosis was made. The diagnosis could have been made earlier ...
In industry, the yeast Rhodotorula mucilaginosa is commonly used for the production of carotenoids. The production of carotenoids is important because they are used as natural colorants in food and some carotenoids are precursors of retinol (vitamin A). However, the identification and molecular characterization of the carotenoid pathway/s in species belonging to the genus Rhodotorula is scarce ...
Rhodotorula spp, though considered a common saprophyte, recently has been reported as causative agent of opportunistic mycoses. We present a case of meningitis in an immunocompromised human immunodeficiency virus infected patient who presented with longstanding fever. He was diagnosed as a case of chronic meningitis. Diagnosis was confirmed by cell cytology, India ink preparation, Gram staining...
The reaction of two D-amino acid oxidases from the yeasts Rhodotorula gracilis and Trigonopsis variabilis with the substrates alanine and valine in their 2-1H and 2-2H forms was studied employing the stopped-flow spectrophotometric technique. The turnover numbers at infinite substrate and oxygen concentrations were: 20,700/4,250 and 1,730/360 ([2-1H]/[2-2H]alanine and valine, respectively) for ...
BACKGROUND Sophorolipids are one of the most promising glycolipid biosurfactants and have been successfully employed in bioremediation and various other industrial sectors. They have also been described to exhibit antimicrobial activity against different bacterial species. Nevertheless, previous literature pertaining to the antifungal activity of sophorolipids are limited indicating the need fo...
سابقه و هدف: فناوری نانو رویکردهای جدیدی برای مبارزه و جلوگیری از بیماری ها از طریق استفاده از اتصال در مقیاس اتمی مواد می گشاید. در میان بهترین مواد با خاصیت ضد میکروبی، نانوذره ی نقره به عنوان یکی از پرکاربردترین نانوذرات در علوم پزشکی، دارویی و بهداشتی مورد استفاده قرار گرفته است. توسعه ی روش های زیستی تولید نانوذرات، به عنوان روشی سازگار با محیط زیست و ارزان، مطرح است. اگرچه اثرات سمی یون ن...
BACKGROUND The production of microbial lipids has attracted considerable interest during the past decade since they can be successfully used to produce biodiesel by catalyzed transesterification with short chain alcohols. Certain yeast species, including several psychrophilic isolates, are oleaginous and accumulate lipids from 20 to 70% of biomass under appropriate cultivation conditions. Among...
