About the Algae: The microalga Porphyridium sp. The P. cruentum were cultured in an experimental tubular photobioreactors as continuously culture method. 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. Porphyridium cruentum is one of the most valued microalgae species able to produce both pigments and exopolysaccharides. is a potential source for several products like fatty acids, lipids, cell-wall polysaccharides and pigments .  |  Glemser M, Heining M, Schmidt J, Becker A, Garbe D, Buchholz R, Brück T. Appl Microbiol Biotechnol. Le porphyridium d’AlgoSource. Various species are cultivated according to demands of different applications Nevertheless, different species need specific conditions such as light, temperature, and adapted culture medium. Thus, the control culture served as a stock culture. In this study, the culture conditions for Porphyridium cruentum were optimized to obtain the maximum biomass and lipid productions. 25 0 obj Beberapa jenis mikroalga yang telah banyak dikembangkan, namun mikroalga dari kelas Rhodophyceae belum terlalu banyak dimanfaatkan … 4 0 obj HHS application/pdf Apex PDFWriter l'Institut Pasteur du Brabant,?
