Abstract

This work is the first of a total of two papers, derived from the results obtained from the first author's master's dissertation in which we sought to evaluate the capacity of biosorption of heavy metals by the fungus Penicillium corylophilum (CCFIOC 4297). This paper presents a comparative study of the removal of nickel ions by the fungus P. corylophilum in vegetative and sporulated forms. For this purpose, the influence of seven parameters using design of experiments Plackett & Burmann was evaluated. Then, the fungus was tested for its ability to biosorption in two different ways: in vegetative and sporulated forms. The results showed great biosorption ability of this fungal lineage and little influence of the tested parameters. The tests for comparative purposes showed a very similar kinetic profile between sporulated and vegetative forms, in which, the fungus sporulated form showed a better performance. 

Keywords: Biosorption, Heavy Metals, Nickel, P. corylophilum.
