A strain of Acidithiobacillus thiooxidans immobilized in polyurethane foam was utilized for H2S removal in a bench-scale trickle-bed reactor, testing the limits of acidity and SO42– accumulation. The use of this acidophilic strain resulted in remarkable stability in the performance of the system. The reactor maintained a >98–99 percent H2S removal efficiency for c of up to 66 ppmv and empty bed residence time ≤12–15 s. Removal of >98 % H2S was achieved under steady-state conditions, over the pH range of 0.44–7.30. Despitethe accumulation of acidity and SO42– (up to 97 g/L), the system operated without inhibition

Pomocí kmene Acidithiobacillus thiooxidans imobilizovaný na polyuretanové pěně jako nosiči ve skrápěnám reaktoru byl odstraňován org. polutant H2S z kontaminovaného vzduchu. Kmen vykazoval významnou stabilitu v systému.Odstranění až 98 procent H2S bylo dosaženo v ustálenám stavu, v pásmu pH 0.44-7,30, s tím, že systém nevykazoval inhibici SO42
