Table 2

Results of cell concentration and productivity obtained from continuous cultivations of C. vulgaris carried out at different dilution rates.

Continuous culture	Dilution rate (day^−1)	𝑋𝑚 or 𝑋𝑆 (mg L^−1)	pH	Biomass productivity (𝑃𝑥, mg L^−1 d^−1)
1	0.1	570 ± 20	10.0 ± 0.2	57.0 ± 1.2
2	0.2	550 ± 10	9.5 ± 0.1	110.0 ± 2.3
3	0.3	420 ± 16	9.3 ± 0.2	126.0 ± 0.8
