Exudates of Rhodotorula mucilaginosa, a yeast commonly found in the rhizosphere, increased hyphal length of the arbuscular mycorrhizal (AM) fungi Gigaspora rosea and Gigaspora margarita. Rhodotorulic acid (RA), a siderophore compound obtained from R. mucilaginosa exudates, increased hyphal length and branching. Thus, the increase in the number of entry points and the higher AM root colonization...

PURPOSE To describe a case of fungal keratitis involving an atypical organism with confirmatory in vivo confocal microscopy and to review the literature on Rhodotorula keratitis. METHODS Case report and review of the medical literature. RESULTS A 22-year-old college student was struck in the left eye with a tree branch and subsequently developed pain, redness and photophobia. Upon presentat...

Yeasts of 17 processed fresh edible (raw) sea urchins obtained from seven countries were analyzed. In total, 45 to 7 x 10(4) colony-forming units (CFU)/g of sea urchins were recovered, and 23 yeast species were identified. Of these species, six pathogenic yeasts (Candida albicans, C. sake, Debaryomyces hansenii, Pichia anomala, Rhodotorula mucilaginosa, and Trichosporon mucoides) were detected ...

We compared the in vitro activities of isavuconazole, posaconazole, voriconazole, and fluconazole against Dipodascus capitatus (n = 21), Saccharomyces cerevisiae (n = 20), Rhodotorula mucilaginosa (n = 18), and Trichosporon spp. (n = 15). The MIC(50)s, MIC(90)s, and MIC ranges (in microg/ml) obtained using the CLSI M27-A3 procedure were as follows: isavuconazole, 0.125, 0.5, and < or = 0.015 to...

  Objective(s): Carotenoids which are naturally synthesized by fungi such as yeasts can act as an antioxidant which is closely related to their ability to decrease the risk of a variety of degenerative diseases. In recent years, the increase of demand for carotenoids obtained from natural sources has promoted major efforts to improve carotenoid production from biological sources such...

Exopolysaccharides (EPSs) are important biopolymers with diverse applications such as gelling compounds in food and cosmetic industries bio-flocculants pollution remediation bioplastics production. This research focuses on enhancing crude EPS production from Rhodotorula mucilaginosa sp. GUMS16 using the central composite design method which five levels of process variables sucrose, pH, ammonium...
