Phenylalanine ammonia-lyase (RgPAL) from Rhodotorula glutinis JN-1 stereoselectively catalyzes the conversion of the l-phenylalanine into trans-cinnamic acid and ammonia, and was used in chiral resolution of dl-phenylalanine to produce the d-phenylalanine under acidic condition. However, the optimum pH of RgPAL is 9 and the RgPAL exhibits low catalytic efficiency at acidic side. Therefore, a mu...

Most eukaryotic oleaginous species are yeasts and among them the basidiomycete red yeast, Rhodotorula (Rhodosporidium) toruloides (Pucciniomycotina) is known to produce high quantities of lipids when grown in nitrogen-limiting media, and has potential for biodiesel production. The genome of the CGMCC 2.1609 strain of this oleaginous red yeast was sequenced using a hybrid of Roche 454 and Illumi...

The 1-oxaspiro[2.5]octane moiety is a common motif in many biologically active spiroepoxide compounds. Stereochemistry plays an important role in the action of these spiroepoxides, since the O-axial C3 epimers are predominantly responsible for biological activity. In view of this, the reactivity of the yeast epoxide hydrolase (YEH) from Rhodotorula glutinis towards both O-axial and O-equatorial...

The imperfect yeasts are divided by Lodder (1934) into two families, Rhodotorulaceae and Torulopsidaceae, distinguished by the occurrence of carotenoid pigments in the former. Lodder employed a form of the Molisch test to demonstrate the carotenoid nature of the pigments in Rhodotaceae. This involved covering a large mass of cells with an alcoholic potassium hydroxide solution and storing in th...

conclusions in humans, rhodotorula species have been recovered as commensal organisms from the nails, the skin, and the respiratory, gastrointestinal (gi), and urinary tracts. due to their presence in the gi flora, broad-spectrum antibiotics could contribute to their overgrowth in the gi tract. localized infections, such as peritonitis, due to rhodotorula species following infected peritoneal d...

A novel single-step microbial transformation process for the efficient production of carthamidin and isocarthamidin from naringenin by yeast Rhodotorula marina in an aerated bioreactor was described. The biotransformation led to the total product concentration of 233 mg/l. The highest conversion efficiency observed for carthamidin was 0.31 mg/mg of naringenin and for isocarthamidin 0.47 mg/mg o...

Rhodotorula glutinis ATCC 204091 is an oleaginous oxidative red yeast that can accumulate lipids to >50% of its biomass when grown with appropriate carbon and nitrogen ratios. It produces a red pigment consisting of useful antioxidants, such as carotenoids, torulene, and torularhodin, when cultivated under carbon-deficient conditions.
