The removal of ρ-chlorophenol in aqueous cultures with free and alginate-immobilized cells of the microalga Tetraselmis suecica
The present study aimed at evaluating the ability
of some isolated cyanobacterial and microalgal strains for
the removal of ρ-chlorophenol (ρ-CP), an environmentally
harmful contaminant. To identify the most efficient species,
a screening program was carried out using 15 microalgal
and cyanobacterial strains. Among them, Tetraselmis suecica
was able to remove 67 % of the ρ-chlorophenol at an
initial concentration of 20 mg L−1 from the medium within a
10-day period. The efficacy of the process was dependent on
the ρ-chlorophenol concentration. At concentrations above
60 mg L−1 of the pollutant, no removal was observed due to
the inhibitory effect of ρ-chlorophenol on the T. suecica
cells. The effect of cell immobilization in alginate beads
on T. suecica removal capacity was also examined. Using
this technique, the removal efficacy for the initial ρ-CP
concentration of 20 mg L−1 increased up to 94 %
