AB - The tanning industry transforms animal skins into leather and produces liquid effluents
with a high organic and inorganic pollutant load. This work evaluated the effect of the tannery
wastewater (TWW) concentration and the light/dark cycle on the production of biomass, carbohydrates, proteins, lipids, and pigments (carotenoids and phycobiliproteins) on two microalgae
(Chlorella sp. and Scenedesmus sp.) and one cyanobacterium (Hapalosiphon sp.). A non-factorial
central experimental design with a response surface was implemented using the STATISTICA 7.0
software. High removal percentages for nitrates (97%), phosphates (73.3%), and chemical oxygen
demand (93.2%) were achieved with the three strains. The results also highlight that the use of
a constant light regime (24:0) and the concentration of real TWW affect the biomass production,
since the highest concentration of biomass recorded was 1.31 g L−1 of Hapalosiphon sp. with 100%
undiluted wastewater.
