  1. * % total dry weight of major cellular composition estimated from S. platensis cell grown under autotrophy [23]. The stoichiometric coefficient of each building block was retrieved and expressed on the basis of one mole of dry cell. DGDG: digalactosyldiacylglycerol; MGDG: monogalactosyldiacylglycerol; SQDG: sulfoquinovosyldiacylglycerol.
