Adaptive evolution was performed for Chlorella sp. to remove phenol in wastewater.
The resulting strain was obtained after 31 cycles for about 95 d.
The resulting strain could grow under 500 mg/L and 700 mg/L phenol.
The growth rates of resulting strain were more than twice of those of original one.
500 mg/L phenol could be fully removed in 7 d by the resulting strain.
