Photoprotective effect of mycosporine-like aminoacids extracts on natamycin, saffron carotenoids and epigallocatechin gallate in acidified beverages exposed to different light sources
(2019-02-01)
Natamycin has been used as a natural food additive to control the growth of many microorganisms. However, this polyene is very sensitive to light exposure. Therefore, the objective of this study was to evaluate the ...
PCR-based method for the rapid identification of astaxanthin-accumulating yeasts (Phaffia spp.)Un método basado en la PCR para la identificación rápida de levaduras acumuladoras de astaxantina (Phaffia spp.)
(Asociación Argentina de Microbiología, 2016-01)
Recientemente, se ha encontrado que la distribución natural, el hábitat y la diversidad genética de levaduras productoras de astaxantina (p. ej., Phaffia rhodozyma, sinónimo Xanthophyllomyces dendrorhous) son mucho mayores ...
Comparative genomics provides new insights into the diversity, physiology, and sexuality of the only industrially exploited tremellomycete: Phaffia rhodozyma
(BioMed Central, 2016-11)
Background: The class Tremellomycete (Agaricomycotina) encompasses more than 380 fungi. Although there are a few edible Tremella spp., the only species with current biotechnological use is the astaxanthin-producing yeast ...
Identificação e caracterização de leveduras produtoras de micosporinas: uma abordagem biotecnológica para novos bloqueadores de radiação UV-A e UV-B
(Universidade Federal de São Paulo, 2023-06-27)
A radiação ultravioleta causa diversos efeitos nocivos aos organismos vivos, em especial na epiderme humana, onde as lesões podem culminar em câncer de pele. As alternativas existentes para evitar ou retardar esses impactos ...

Síntesis de filtros UV (micosporinas) en Phaffia rhodozyma. Caracterización de los genes y enzimas responsables
(2018-03-28)
La exposición a la radiación ultravioleta (RUV) es perjudicial no solo para los organismos vivos, sino también en los niveles más complejos de organización, como las comunidades y los ecosistemas. Muchos productos químicos ...
Contrasting patterns of MAAs accumulation in two populations of the copepod Boeckella gracilipes
(Royal Society Of Chemistry, 2014)
The bio-accumulation of mycosporine-like amino acids (MAAs) is common in planktonic copepods that inhabit environments exposed to high levels of solar radiation. MAAs accumulation in copepods can be affected both by extrinsic ...
Role of ROX1, SKN7, and YAP6 stress transcription factors in the production of secondary metabolites in xanthophyllomyces dendrorhous
(MDPI, 2022)
Xanthophyllomyces dendrorhous is a natural source of astaxanthin and mycosporines. This
yeast has been isolated from high and cold mountainous regions around the world, and the production
of these secondary metabolites ...
The Effects of NO– 3 Supply on Mazzaella laminarioides (Rhodophyta, Gigartinales) from Southern Chile
(American Society of PhotobiologyHoboken, 2014-10-30)
The effects of nitrate supply on growth, pigments, mycosporine-like amino acids (MAAs), C:N ratios and carrageenan yield were investigated in Mazzaella laminarioides cultivated under solar radiation. This species is ...
Photochemistry and Photophysics of Shinorine Dimethyl Ester
(Wiley Blackwell Publishing, Inc, 2018-09)
The photostability and photophysical properties of the dimethyl ester of the mycosporine-like amino acid shinorine have been experimentally evaluated in aqueous solution and in the presence of direct micelles prepared with ...
