Analysis of microbial composition on biotrickling filter used to remove SO2
净化SO2的生物膜填料塔中微生物类群分析

In this work, a bacterial strain Acidithiobacillus thiooxidans IEL001 and an acidophilic fungal strain Bispora sp.IEL002 was isolated from the biotrickling filter used to remove sulfur dioxide. Due to the extremely acidic environment and scarcity of organic nutrition in the biotrickling filters, only a low microbial diversity was observed. It was also found that Bispora sp. IEL002 could facilitate Acidithiobacillus thiooxidans IEL001 in oxidizing sulfur, but Bispora sp. IEL002 itself could not oxidize sulfur at all.
