| evaluation of the relationship between the incubation time and carotenoid production in rhodotorula slooffiae and r. mucilaginosa isolated from leather tanning wastewater . | 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 as pigmented yeasts. the aim of this study was comparing incubation time and carotenoid production in rhodotorula slooffiae and r ... | 2013 | 24379970 |
| application of high-content image analysis for quantitatively estimating lipid accumulation in oleaginous yeasts with potential for use in biodiesel production. | biodiesel from oleaginous microorganisms is a viable substitute for a fossil fuel. current methods for microorganism lipid productivity evaluation do not analyze lipid dynamics in single cells. here, we described a high-content image analysis (hca) as a promising strategy for screening oleaginous microorganisms for biodiesel production, while generating single-cell lipid dynamics data in large cell density. rhodotorula slooffiae yeast were grown in standard (ctl) or lipid trigger medium (ltm), a ... | 2016 | 26744805 |
| application of issr-pcr for rapid strain typing of debaryomyces hansenii isolated from dry-cured iberian ham. | yeast populations of dry-cured iberian ham isolated from seven industries in the province of badajoz were characterized by issr-pcr using the (cag)4 primer and pcr-rflp of the its1-5.8s rrna-its2 fragment, and identified by dna sequencing. a total of 242 isolates were analyzed, indicating the primary species present was debaryomyces hansenii at 80.9% of the isolates followed by candida zeylanoides at 10.3% of the isolates. the remainders of isolates were identified as yamadazyma triangularis, sp ... | 2014 | 24929738 |
| molecular characterization and lipase profiling of the yeasts isolated from environments contaminated with petroleum. | in the present study, 120 yeast isolates from different sources (active sludge, soil, and wastewater samples obtained from petroleum refinery and soil contaminated by petroleum) were obtained. the yeast isolates were screened for lipase production and twelve of the isolates (d3, d17, d24, d27, d30, d38, d40, d42, d44, d46, d56, and d57) exhibited lipase activity. molecular characterization of the yeasts showing the lipase production was performed with rflp of its1-5.8s-its2 and 18s rrna and sequ ... | 2014 | 23712936 |
| rhodotorula benthica sp. nov. and rhodotorula calyptogenae sp. nov., novel yeast species from animals collected from the deep-sea floor, and rhodotorula lysiniphila sp. nov., which is related phylogenetically. | three novel species of the genus rhodotorula are described. rhodotorula benthica sp. nov. (type strain jcm 10901(t) = sy-91(t)) and rhodotorula calyptogenae sp. nov. (type strain jcm 10899(t) = sy-86(t)) were respectively isolated from the tubeworm lamellibrachia sp. and the giant white clam calyptogena sp., collected from the deep-sea floor of the pacific ocean off japan. rhodotorula lysiniphila sp. nov. (type strain jcm 5951(t)) is proposed for strains isolated previously in japan and pakistan ... | 2003 | 12807219 |
