Abstract
The invention relates to a process and an apparatus for the removal of sparingly-soluble gaseous substances, especially sulfur-containing substances from waste gases with the aid of microorganisms. The waste gas containing the sparingly-soluble gas is directed (24) in the form of small gas bubbles into a suspension (16) of degrading microorganisms. A gas which has been pre-cleaned in this way is preferably led to another bioreactor (10), where microorganisms degrade the contaminant. The invention also relates to a new microorganism which is capable of degrading carbon disulfide and hydrogen sulfide.
