英文摘要	microalgal starch is considered a promising feedstock for bioethanol production. the biomass and starch accumulation in the marine microalga tetraselmis subcordiformis were characterized under different salinities in response to nitrogen repletion (+n) or depletion (-n) at high irradiance (hi) or low irradiance (li). under favorable nutritional conditions (hi+n), biomass accumulation was seldom affected under 20% normal salinity, though starch accumulation were somewhat reduced. increased salinity impaired overall biomass and starch accumulation, though it led to a temporary starch accumulation at initial cultivation phase. under nitrogen deprivation, decreased salinity strengthened biomass and starch accumulation regardless of irradiance. the highest starch content of 58.2% dry weight and starch productivity of 0.62 g l-1 d(-1) were obtained under hi-n with 20% normal salinity. decreased salinity combined with -n generated moderate stress to facilitate starch accumulation. salinity manipulation can be effectively applied for enhanced starch production in marine microalgae.
