These compounds are also important nutrient sources for
aquatic plants and specially algae (Finlayson et al., 1987;
Tiow-Suan & Anthony, 1988; Sevrin-Reyssac, 1998). Algae
use solar energy, while absorbing nutrients from wastewater
to fix carbon substances to produce plant biomass that
would constitute a valuable source of compounds for
animal feeding supplement and that can be at the same time,
as a decaying organic pollutant that decreases water
pollution.
