✦ Synopsis
The more complex inhibitory effect of As(m) than that of As(V) on Fe(n) oxidation in a non-growing Thiobacillus ferrooxidans suspension was demonstrated. The yield of arsenic bioextraction from a chalcopyrite concentrate was not affected by arsenic inhibition due to the low sensitivity of the strain to arsenic ions, supported by a spontaneous conversion of As(II1) to As(V).
