Short communication: Mycosporine-like amino acids protect natamycin against photodegradation in milk exposed to fluorescent or light-emitting diode light
(2019-06-01)
Natamycin has been used as a natural antimicrobial in dairy products, but the poor light stability of natamycin can limit usefulness in food products. Mycosporine-like amino acids are strong UV absorbers and might be useful ...
Palythine-threonine, a major novel mycosporine-like amino acid (MAA) isolated from the hermatypic coral Pocillopora capitata
(ELSEVIER SCIENCE SA, 2009)
Using a high-resolution reverse-phase liquid chromatography method we found that the tissues of the hermatypic coral Pocillopora capitato (collected in Santiago Bay, Mexico) contain a high diversity of primary and secondary ...
Influence of mycosporine-like amino acids and gadusol on the rheology and Raman spectroscopy of polymer gels
(IOS Press, 2014-11)
BACKGROUND: The amphiphilic nature of polymers allows them to be widely incorporated as carriers in different pharmaceutical applications since they are able to work as vehicles for hydro- or lipo-soluble actives. OBJECTIVE: ...
Diurnal changes in the composition of Mycosporine-like Amino Acids (MAA) in Corallina officinalis
(Referee Gateway, 2006-12)
Thalli of Corallina officinalis Linnaeus were harvested at 1-h intervals during low tide in Barrancas Blancas (Patagonia, Argentina) on clear days to examine diurnal changes of the UV-absorbing mycosporine-like amino acids ...
A theoretical and mass spectrometry study of the fragmentation of mycosporine-like amino acids
(ELSEVIER SCIENCE BV, 2008)
In the present study, the mycosporine-like amino acids (MAAs) were isolated from the marine red alga Gracilaria tenuistipitata and analysed by high-resolution accurate-mass sequential mass spectrometry (MSn). In addition ...
Nitrate reduces the negative effect of UV radiation on photosynthesis and pigmentation in Gracilaria tenuistipitata (Rhodophyta): the photoprotection role of mycosporine-like amino acids
(INT PHYCOLOGICAL SOCLAWRENCE, 2012)
Photoprotection of the agarophyte red alga Gracilaria tenuistipitata against ultraviolet radiation (UVR) was investigated in algae submitted for 1 week to photosynthetically active radiation (PAR, 260 mu mol photons m(-2) ...
Effects of stressing high PAR on mycosporine-like amino acids in the red alga Gracilariopsis tenuifrons (Gracilariales, Rhodophyta)
(Society for Medicinal Plant and Natural Product ResearchGuimarães, 2014)
Studies in Rhodophyta species have been carried out to understand the mechanism of photoprotection against excessive photosynthetically active radiation (PAR). However, few studies concerning on the role of mycosporine-like ...
Analyses of photoprotective compounds in red algae from the Brazilian coast
(Sociedade Brasileira de Farmacognosia, 2011)
Qualitative and quantitative studies of mycosporine-like amino acids (MAAs) in three species of the genus Gracilaria Greville (G. birdiae, G. domingensis and G. tenuistipitata) were performed. A simple and efficient ...
UV-radiation effects on photosynthesis and photoprotection in gametophytic and sporophytic stages of the freshwater red alga Kumanoa ambigua (Rhodophyta, Batrachospermales)
(Wiley-Blackwell, 2018-04-01)
The aim of this study was to analyze the photosynthetic performance of gametophytic and sporophytic (Chantransia') stages of Kumanoa ambigua in culture under UV radiation. We hypothesized that both life history stages of ...
Mycosporine-like amino acids versus carrageenan yield in Mazzaella laminarioides (Gigartinales; Rhodophyta) under high and low UV solar irradiance
(2017)
The effects of increased solar photosynthetically active radiation (PAR) and ultraviolet radiation (UVR) on biomass, mycosporine-like amino acid (MAA) content, and carrageenan yield were studied for 14 days in tank-cultivated ...
