采用堆肥沿着木屑填料、添加二甲基硫醚（DMS）降解菌球形芽孢杆菌（Bacillus sphaericus）的小型生物滤池对DMS的生物处理进行了研究。在最佳负荷为0.484g/m3/h、最佳空床接触时间（EBCT）为384 s、平均含水率为65- 70%的条件下，生物过滤塔对DMS的去除率为62-74%。DMS的生物降解产物为硫化物、硫代硫酸盐和硫酸盐。生物过滤器的微生物状态评价表明，除B外，还存在其他细菌培养物，即多粘类芽孢杆菌和巨大芽孢杆菌。球形的。
Biological treatment of dimethyl sulphide (DMS) was investigated in a bench-scale biofilter, packed with compost along with wood chips, and enriched with DMS degrading microorganism Bacillus sphaericus. The biofilter could remove 62–74% of the inlet DMS, at an optimum loading of 0.484g/m3/h with optimum empty bed contact time (EBCT) of 384s and an average moisture range of 65–70%. The biodegradative products of DMS were sulphide, thiosulphate and sulphate. Evaluation of microbiological status of the biofilter indicated the presence of other bacterial cultures viz. Paenibacillus polymyxa, and Bacillus megaterium, besides B. sphaericus.
