Adsorption process and mechanism of heavy metal ions by different components of cells, using yeast (<i>Pichia pastoris</i>) and Cu<sup>2+</sup> as biosorption models

Abstract
The Cu<sup>2+</sup> first bound to the outer mannan and finally entered the cytoplasm. During the whole adsorption process, the number of adsorption sites in the outer and middle cell walls was the largest, and then gradually decreased.
