AbstractMicroalgal starch is a potential feedstock for bio-fuel production. Nutrient stress is widely used to stimulate starch accumulation in microalgae. Cell growth and starch accumulation in the marine green microalga Tetraselmis subcordiformis were evaluated under extracellular phosphorus deprivation with initial cell densities (ICD) of 1.5, 3.0, 6.0, and 9.0x10(6) cells mL(-1). The intracellular stored phosphorus supported cell growth when extracellular phosphorus was absent. The maximum starch content of 44.1 % was achieved in the lowest ICD culture, while the maximum biomass productivity of 0.71 g L-1 day(-1), starch concentration of 1.6 g L-1, and starch productivity of 0.30 g L-1 day(-1) were all obtained in the culture with the ICD of 3.0x 10(6) cells mL(-1). Appropriate ICD could be used to regulate the intracellular phosphorus concentration and maintain adequate photosynthetic activity to achieve the highest starch productivity, along with biomass and starch concentration. The recovery of phosphorus-deprived T. subcordiformis in medium containing 0.5, 1.0, or 6.0 mM KH2PO4 was also tested. Cell growth and starch accumulation ability could be recovered completely. A phosphorus pool in T. subcordiformis was shown to manipulate its metabolic activity under different environmental phosphorus availability. Though lower starch productivity and starch content were achieved under phosphorus deprivation compared with nitrogen-or sulfur-deprived conditions, the higher biomass and starch concentration make T. subcordiformis a good candidate for biomass and starch production under extracellular phosphorus deprivation.
