Figure 5
Bar plots for a comparison of the effects of an initial abundance of Pseudokirchneriella subcapitata and Chlorella vulgaris, the initial abundance ratio, and absolute initial abundance. The green bar and orange bar represent the rate of change of the maximum abundance ratio when each type of initial abundance increases and decreases by 20%, respectively. The initial abundance levels of P. subcapitata and C. vulgaris were 2.5 × 105 and 2.5 × 106 cells mL−1, respectively. Asterisks indicate that a data point was excluded from the outcome determination owing to severe inhibition of algal growth.
