Abstract(s)
An aquatic communitywas recovered from a waste discharge container fed with several aromatic pollutants. After 3
months of selective enrichment with p-chlorophenol and p-nitrophenol, two microalgae species, Chlorella vulgaris and
Coenochloris pyrenoidosa, were recovered from the microbial consortium. As an axenic culture, this microalgae
consortium was able to remove p-chlorophenol under different photo-regimes. Cultures grown under a 24 h light regime
were capable of biodegrading 50mg l 1 of p-chlorophenol within 5 days. Addition of zeolite, an adsorbing material, did
not improve the p-chlorophenol removal. However, when p-chlorophenol at 150mg l 1 was fed to the culture
supplemented with zeolite, the growth rate of the consortium improved, but the lag phase was longer (16 against 14
days in the absence of zeolite).
