Table 5 Performance based on biomass concentration, lipid accumulation, and CO 2 fixation of salinity-gradient culturing of Chlamydomonas sp. JSC4 with stepwise addition of sea salt at different increments

From: Optimizing biodiesel production in marine Chlamydomonassp. JSC4 through metabolic profiling and an innovative salinity-gradient strategy
