Abstract
Exopolymers produced by bacteria cells during copper bioleaching from copper sulphides could modify the relative cell surface charge and thus change the relation between cell and substratum surfaces. All examined bacterial strains showed a hydrophilic cell surface independent of relative surface charge and adhesion depended on presence or absence of exopolymer. The effect of exopolymers on adhesion processes differed according to the strain and was clearer in the case of pure culture. © Rapid Science Ltd. 1998
