Abstract
A clear relationship was observed between the adhesion of Thiobacillus ferrooxidans and Thiobacillus thiooxidans to different substrates and the nutrient composition of the culture medium used for growth. Howev er, a linear relationship between the percentage of attachment and the efficiency of bioleaching by these microorganisms was not found. The direct attack mechanism on insoluble sulphides by Thiobacillus ferroox idans was confirmed in the absence of iron. (C) 1997 Elsevier Science Ltd.
