Mycosporine-like amino acids (MAAs) were studied in zooplankton from 13 Argentinian lakes covering a broad range in altitude, maximum depth and physico-chemical properties of the water. Four to nine different MAAs (predominantly porphyra-334 and shinorine) were found in the copepods Boeckella gibbosa, B. gracilipes, B. meteoris and Parabroteas sarsi, and in the ciliate Stentor amethystinus, whi...
Searching for economical, nonconventional sources of iron is important in underdeveloped countries to combat iron deficiency and anemia. Our objective was to study iron, vitamin C, and phytic acid composition and also iron bioavailability from 4 species of marine algae included in a rice-based meal. Marine algae (Ulva sp, Sargassum sp, Porphyra sp, and Gracilariopsis sp) were analyzed for month...
A novel antifungal protein (SAP) was found in the culture supernatant of a marine bacterium, Streptomyces sp. strain AP77, and was purified. This protein was characterized by chemical, biochemical, and biological analyses. By using gel filtration, the molecular mass of SAP was estimated to be 160 kDa. Structural analysis of SAP by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and ma...
The present study aimed to examine the signaling pathways and enzyme activity associated with the protective effect of Porphyra yezoensis glycoprotein (PYGP) on D‑galactosamine (D‑GaIN)‑induced cytotoxicity in Hepa 1c1c7 cells. D‑GaIN is commonly used to induce hepatic injury models in vivo as well as in vitro. PYGP was extracted from Porphyra yezoensis, a red algae distributed along the coasts...
BACKGROUND Pyropia haitanensis and P. yezoensis are two economically important marine crops that are also considered to be research models to study the physiological ecology of intertidal seaweed communities, evolutionary biology of plastids, and the origins of sexual reproduction. This plastid genome information will facilitate study of breeding, population genetics and phylogenetics. PRINCI...
