KUFFERATH Ing?nieur agricole, docteur en sciences naturelles, Chef de laboratoire ? Porphyridium cruentum microalgae have great potential to be developed as a source of active ingredients in various fields of health. The cell density of P. cruentum was held around 25.1 x 106 cells mL-1 after the 9th day until the end of experiment with an average harvesting of 10%. The maximum biomass concentration of 0.91 g dcw/L was obtained with an aeration rate of 0.75 vvm, a light intensity of 300 μmol m-2 s-1, and a photoperiod of 24:0 h. The maximum lipid production of 51.8% (w/w) was obtained with a light intensity of 400 μmol m-2 s-1 and a photoperiod of 18:6 h. Additionally, the eicosapentaenoic acid and unsaturated fatty acid contents reached 30.6% to 56.2% at pH 6.0. (Rhodophyta) is a potential source for several products like fatty acids, lipids, cell-wall polysaccharides and pigments. A study was made of the effect of temperature, detention period, light intensity, and salinity on the growth rate and over-all light energy conversion efficiency of Porphyridium cruentum cultured on a medium consisting of concentrated sea water and sewage enriched with … AlgoSource a choisi un système de culture fermé pour cultiver cette souche afin de réduire les contaminations et d’augmenter les performances de croissance et de … Porphyridium cruentum est cultivée à des températures entre 20 et 25°C aussi bien dans des bassins ouverts de type raceways que dans des réacteurs fermés et éclairés par le soleil ou une lumière artificielle.
