Immobilization of the chemoautotroph Thiobacillus denitrificans for the oxidation of hydrogen sulfide.

摘要

The chemoautotroph Thiobacillus denitrificans (strain F) has been immobilized by aerobic coculture with floc-forming heterotrophs from an activated sludge treatment facility. Floc with excellent settling properties was produced. No addition of organic carbon was required. Presumably, the heterotrophs used waste products of the T. denitrificans or cell lysis products as a source of carbon and energy.;Subsequently, the immobilized T. denitrificans was used to remove H
