Influence of the particle size and hydrocolloid type on lipid digestion of thickened emulsions

Riquelme, Natalia; Robert Canales, Paz; Troncoso, Elizabeth; Arancibia, Carla (Royal Society of Chemistry, 2020)

Hydrocolloids are used as stabilizing agents in order to enhance the physical stability of emulsions during their storage. However, they can also play an important role in nutrient release and bioavailability. In this ...

Molecular Characterization and Functional Analysis of Cytochrome b5 Reductase (CBR) Encoding Genes from the Carotenogenic Yeast Xanthophyllomyces dendrorhous

Gutiérrez, María Soledad; Rojas Garrido, María Cecilia; Sepúlveda, Dionisia; Baeza Cancino, Marcelo; Cifuentes Guzmán, Víctor; Alcaíno Gorman, Jennifer (Public Library Science, 2015)

The eukaryotic microsomal cytochrome P450 systems consist of a cytochrome P450 enzyme (P450) and a cytochrome P450 redox partner, which generally is a cytochrome P450 reductase (CPR) that supplies electrons from NADPH. ...

Cloning of the cytochrome p450 reductase (crtR) gene and its involvement in the astaxanthin biosynthesis of Xanthophyllomyces dendrorhous

Alcaíno Gorman, Jennifer; Barahona‑Crisóstomo, Salvador; Carmona, Marisela; Lozano, Carla; Marcoleta, Andrés; Niklitschek, Mauricio; Sepúlveda, Dionisia; Baeza Cancino, Marcelo; Cifuentes Guzmán, Víctor (BIOMED CENTRAL LTD, 2008-10-06)

Background: The yeast Xanthophyllomyces dendrorhous synthesizes astaxanthin, a carotenoid with high commercial interest. The proposed biosynthetic route in this organism is isopentenylpyrophosphate (IPP) -> geranyleranyl ...

Increased Nicotiana tabacum fitness through positive regulation of carotenoid, gibberellin and chlorophyll pathways promoted by Daucus carota lycopene beta-cyclase (Dclcyb1) expression

Moreno, J. C.; Cerda, A.; Simpson, K.; López Díaz, I; Carrera, E.; Handford, Michael; Stange Klein, Claudia (Oxford Univ Press, 2016)

The expression of Dclcyb1 in tobacco induces a positive feedback on the isoprenoid, carotenoid, gibberellin and chlorophyll pathways leading to an enhancement in fitness, biomass, photosynthetic efficiency and carotenoid ...

The involvement of mig1 from xanthophyllomyces dendrorhous in catabolic repression: An active mechanism contributing to the regulation of carotenoid productiom

Alcaíno Gorman, Jennifer; Bravo, Natalia; Córdova, Pamela; Marcoleta Caldera, Andrés; Contreras, Gabriela; Barahona Crisóstomo, Salvador; Sepúlveda, Dionisia; Fernández Lobato, María; Baeza Cancino, Marcelo; Cifuentes Guzmán, Víctor (Public Library of Science, 2016)

The red yeast X. dendrorhous is one of the few natural sources of astaxanthin, a carotenoid used in aquaculture for salmonid fish pigmentation and in the cosmetic and pharmaceutical industries for its antioxidant properties. ...

Oral Supplementation of beta-Carotene Benefits the Hepatic Structure and Metabolism in Mice (Mus musculus) Exposed to A Chronic Ethanol ConsumptionLa Suplementación Oral de Betacaroteno Beneficia la Estructura Hepática y el Metabolismo en Ratones (Mus musculus) Expuestos a un Consumo Crónico de Etanol

Sandoval, Cristian; Vasquez, Belgica; Vasconcellos, Adriana; Souza-Mello, Vanessa; Adeli, Khosrow; Mandarim-De-Lacerda, Carlos; del Sol, Mariano (UNIV KEBANGSAAN MALAYSIA, 2023)

Genome-scale metabolic models of Microbacterium species isolated from a high altitude desert environment

Mandakovic, Dinka; Cintolesi, Ángela; Maldonado, Jonathan; Mendoza, Sebastián; Aite, Meziane; Gaete, Alexis; Saitua, Francisco; Allende, Miguel; Cambiazo Ayala, Liliana; Siegel, Anne; Maass Sepúlveda, Alejandro; González Canales, Mauricio; Latorre Mora, Mauricio (Nature, 2020)

The Atacama Desert is the most arid desert on Earth, focus of important research activities related to microbial biodiversity studies. In this context, metabolic characterization of arid soil bacteria is crucial to understand ...

Differential Contribution of the First Two Enzymes of the MEP Pathway to the Supply of Metabolic Precursors for Carotenoid and Chlorophyll Biosynthesis in Carrot (Daucus carota)

Simpson Alfaro, Kevin; Quiroz Iturra, Luis; Rodríguez Concepción, Manuel; Stange Klein, Claudia (Frontiers Media, 2016)

Carotenoids and chlorophylls are photosynthetic pigments synthesized in plastids from metabolic precursors provided by the methylerythritol 4-phosphate (MEP) pathway. The first two steps in the MEP pathway are catalyzed ...

Regulation of carotenogenesis in the red yeast Xanthophyllomyces dendrorhous: the role of the transcriptional co-repressor complex Cyc8-Tup1 involved in catabolic repression

Córdova, Pamela; Alcaíno Gorman, Jennifer; Urrutia Bravo, Natalia Agnetta; Barahona, Salvador; Sepúlveda, Dionisia; Fernández Lobato, María; Baeza Cancino, Marcelo; Cifuentes Guzmán, Víctor (Biomed Central, 2016)

Background: The yeast Xanthophyllomyces dendrorhous produces carotenoids of commercial interest, including astaxanthin and beta-carotene. Although carotenogenesis in this yeast and the expression profiles of the genes ...
