Discs of P. columbina were incubated with three ammonium concentrations (0, 50, and 300lM NH4Cl) in an illuminated chamber (PAR5300lmol photons . m 2 . s , UVA515W .m , UVB5 0.7W .m ) at 151 C. Algae incubated at 300lM ammonium showed a significant increase (Po0.05) in the concentration of mycosporine-like amino acids (MAAs) compared with the initial value or with the other ammonium treatments.. The increase of MAAs was, however, a function of the quality of irradiance received, with a higher increase in samples exposed to UVA compared with UVB (29% and 5% increase, respectively).

Also, photosynthetic activity as in vivo chlorophyll fluorescence of photosystem II, i.e. optimum quantum yield (Fv/Fm), electron transport rate (ETR) and quantum efficiency, were examined..

Suspension:Article Title: Optimization of the production of lipids and carotenoids in the microalga Golenkinia aff. brevispicula Article Snippet: Microalgae are a promising platform to produce natural pigments and lipids when compared to traditional sources, since they present faster growth and biomass productivity and there is a wide diversity that has not been studied yet.. The green microalgae belonging to the genus Golenkinia presents few reports of its biomass production and applications.. In this work, the productivity of lipids and carotenoids was studied in the strain Golenkinia aff. brevispicula FAUBA-3 using a two-stage cultivation system: a first step for biomass production under semicontinuous cultures, and a second step for the accumulation of lipids and carotenoids under batch salinity stress (35 g L−1). |
