Biosynthesis of biodegradable polymers polyhydroxyalkanotes (PHAs) have been studied extensively in wild type and genetically modified prokaryotic cells, however the content and structure of PHAs in wild type yeasts is not well documented. The purpose of this study was to screen yeast isolates collected from different ecosystems for their ability to accumulate PHAs. Identification of the isolat...
Rhodotorula species live in the environment, but can also colonize human epithelium, as well as respiratory, and gastrointestinal tracts. Reports of infection, especially in the past 2 decades, have noted increasing numbers of Rhodotorula infections, particularly in immunocompromised hosts, leading it to be considered emerging opportunistic pathogen. The major risk factors for infection were pr...
Carotenoids from some of the coloured yeasts like Rhodotorula, Phaffia rhodozyma have attracted commercial interest as a natural pigment for foods. Red yeast isolated from the contaminated PDA plate yeast has been found to produce carotenoids. This red was characterized and designated as Rhodotorula glutinis DFR-PDY. The isolated crude pigment from the red yeast Rhodotorula glutinis DFR-PDY was...
Yeast exopolysaccharide (EPS) are composed of unique sugar units, which offers an interesting perspective with respect to various food applications. This study aimed to characterize the EPS from Rhodotorula minuta BIOTECH 2178. Toxicological assessment of the EPS was investigated to ensure that it is safe for human consumption. The yeast EPS revealed high total sugar composition (59.2162-47%) a...
Rhodotorula yeasts were isolated from various local sources in Damascus, Syria, during 2012 and 2013. Fifty isolates (23 from leaves trees, 13 from different soils, 6 from different meats, 6 from dairy products, 1 pickle and 1 traditional sweet) were identified using API 20C AUX system. Isolated yeasts were classified into three Rhodotorula species: R. mucilaginosa, R. glutinis and R. minuta re...
Stereospecifically labeled mevalonic acid was incorporated into the carotenoids of Rhodotorula. The randomized results are discussed in relation to mechanisms proposed for the conversion of isopentenyl pyrophosphate to dimethylallyl pyrophosphate and the prenol transferase enzyme system to Rhondotorula rubra.
The paper presents the research work done to study the discontinuous bioprocess for the intracellular carotenoidic pigment torularhodin formation with the yeast Rhodotorula rubra ICCF 209. The growth and carotenoid biosynthesis of the yeast Rhodotorula rubra was studied by cultivation in 3.7 L Bioengineering AG lab bioreactor with mechanical stirring at an air flow rate of 200 L/h and agitation...
