dc.description.abstract Acid mine drainage (AMD) is a common result of mining activities caused by bacterial oxidation of sulphide minerals (pyrite) that results in sulphate rich waste water. AMD can be treated biologically in the presence of sulphate reducing bacteria (SRB) and organic matter such as ethanol. During this process hydrogen sulphide (H2S) is formed, which can have toxic effects on the methanogenic activity (Koster et al.,1986) as well as on the sulphidogenic bacteria (Okabe et al., 1995). Lens & Hulshoff Pol (2000) showed that at neutral pH values, free H2S (which is more toxic than HS-), accounts for 50% of total dissolved sulphide, whereas at pH 8 it is only around 10%. en
