∗Lag phase duration (LPD), growth rate (r), doubling time (Td), for Chloromonas brevispina (CB), Dunaliella salina (DS), and Chlorella vulgaris (CV) were the averages of the duplicate experiments reported in Supplementary Table 12 with the uncertainties on LPD, doubling time and growth rate are propagated for the average of the duplicate experiments.
aLag phase duration (LPD) was estimated as 15% of the culture carrying capacity and is reported in days.
bGrowth rate (r) as solved using the exponential growth equation (Eq. 3) and is reported as per day.
cDoubling time (Td) is the time it takes for a population to double in size found using Eq. 4 and is reported in days.
dCorrelation coefficient (R2) is used to measure the goodness of fit for non-linear regression.
