Dynamic metabolic profiling of Chlamydomonas sp. during semi-continuous cultivation. KOR1 and KAC1801 cells were harvested on day 1.5 of semi-continuous culture, and intracellular metabolites were labeled with ¹³C by adding NaH¹³CO₃. The x-axes show the labeling time and the y-axes show the ¹³C labeling ratio. Error bars indicate the standard deviation of three replicate experiments (*p < 0.05, **p < 0.01 via Welch’s t-test)
