of a multilayer, but for Allura red biosorption occurred by formation of a
monolayer on the S. platensis surface. The maximum biosorption capac-
ities were 363.2 mg g -1 and 468.7 mg g -1 for Tartrazine and Allura red,
respectively. The thermodynamic evaluation showed that the biosorption
of azo dyes onto S. platensis was a spontaneous, favorable and exothermic
