Abstract

Dimethylsulphide degradation by intact cells of Thiobacillus thioparus TK-m was stimulated by the addition of divalent metal ions (Ca2+ > Mg2+ > Mn2+). Mixtures of divalent ions were also found to be stimulatory with the exception of the Ca2+ + Mn2+combination (Mg2+ + Mn2+ > Mg2+ + Ca2+ > Ca2+ + Mn2+).

 

Key words: Thiobacillus thioparus Tk-m, dimethyl sulphide, divalent metal ions, degradation.
