摘要: The influence of mineral nutrients on the growth and self-flocculation Tolypothrix tenuis was studied. identification possible limiting in culture medium performed by biomass elemental composition approach. A factorial experimental design used order to estimate contribution macronutrients micronutrients, as well their interactions. Iron identified be medium. micronutrients influenced mainly cellular without effects self-flocculation. Conversely, capacity increased at higher concentrations macronutrients. optimization nutrition T. allowed a 73% increase final level 3.5 times flocculation rates.
