Cold stress treatment enhances production of metabolites and biodiesel feedstock in Porphyridium cruentum via adjustment of cell membrane fluidity

Abstract Porphyridium cruentum, a cell-wall-free marine Rhodophyta microalga was cultured under a 5-day cold stress at 0 °C and 15 °C, after reaching the late logarithmic growth phase. Compared with the control at 25 °C, the cold stress treatment significantly (p
