Corresponding Author. The eicosapentaenoic acid content was increased by pH optimization. The microalga Porphyridium cruentum (Rhodophyta) has several industrial and pharmaceutical uses, especially for its polysaccharide production. The present study was undertaken to examine effect of myo-inositol on growth of Porphyridium cruentum. Porphyridium cruentum was cultured with modified F/2 medium in 14-L photo-bioreactors using a two-phase culture system, in which the green (520 nm) and red (625 nm) light-emitting diodes (LEDs) were used during the first and second phases for biomass production and lipid production, respectively. <>stream l'Institut Pasteur du Brabant,?
