title: Concentration of sterols of Porphyridium cruentum biomass at stationary phase.
abstract: The objective of this study was to investigate sterols content of Porphyridium cruentum batch cultured in laboratory at 18 degrees C and harvested in the stationary. The sterol distribution of this species is characterized by a predominance of cholesterol, with values as 199.0 mg 100 g(-1) freeze dry weight (92.2%). The second most important sterol was stigmasterol (4.9%) followed by beta-sitosterol (2.2%). Studied sterols give to this species a special importance in for being used in food as supplements/nutraceuticals (including aquaculture).
