Genetic transformation of astaxanthin mutants of Phaffia rhodozyma
(1998)
Stable red astaxanthin-producing transformants were obtained after genetic transformation of two Phaffia rhodozyma mutants. A yellow mutant, accumulating β-carotene, and an albino mutant, accumulating phytoene, from P. ...
Elementos genéticos extracromosómicos en Phaffia rhodozyma
(Universidad de Chile, 1995)
En este trabajo, se presenta la caracterizacion de EGEs y VLPs de
Phaffia rhrodozyma, una levadura productora de carotenoides de la
subdivisión Deuteromycotina (Blastomycetes), aunque sus propiedades
indican que es un ...

Advances and trends in biotechnological production of natural astaxanthin by Phaffia rhodozyma yeast
(2021-01-01)
Astaxanthin (AXT) is a natural xanthophyll with strong antioxidant, anticancer and antimicrobial activities, widely used in the food, feed, pharmaceutical and nutraceutical industries. So far, 95% of the AXT global market ...
Presence of double-stranded RNA and virus-like particles in Phaffia rhodozyma
(Springer-Verlag, 1994)
Four double-stranded RNA (dsRNA) molecules were isolated from Phaffia rhodozyma UCD 67-385. Their molecular sizes were approximately 4.3, 3.1, 0.9 and 0.75 kilobase pairs (kbp) as determined by agarose-gel electrophoresis ...
An eco-friendly approach for the recovery of astaxanthin and β-carotene from Phaffia rhodozyma biomass using bio-based solvents
(2022-02-01)
There is a growing demand in the development of environmentally friendly technologies, based on the use of more biocompatible solvents for the recovery of natural bioactive compounds. In this work, the red yeast Phaffia ...
Genetics and electrophoretic karyotyping of wild-type and astaxanthin mutant strains of Phaffia rhodozyma
(1997)
In this work we establish the chromosomal composition of a wild-type, one astaxanthin and two β-carotene overproducer strains of the red yeast Phaffin rhodozyma. The method used has been pulsed field gel electrophoresis, ...
Study of the expression of carotenoid biosynthesis genes in wild-type and deregulated strains of Xanthophyllomyces dendrorhous (Ex.: Phaffia rhodozyma)
(Sociedad de Biología de Chile, 2004)
Study of the expression of carotenoid biosynthesis genes in wild-type and deregulated strains of xanthophyllomyces dendrorhous (ex: Phaffia rhodozyma)
(Society of Biology of Chile, 2004)
The expression, at the mRNA level, of carotenoid biosynthetic genes from Xanthophyllomyces dendrorhous was studied by RT-PCR. The experimental conditions for the RT-PCR assay were standardized to quantify the relative ...
