| dc.description.abstract | This study focus on isolation sulfur oxidizing bacteria (SOBs) from alum soil
and activated sludge. 11 strains of bacteria were isolated and tested sulfur-oxidizing
abilities. The experiment was designed for 11 strains of bacteria for evaluating the
thiosulfate and Dimethyl sulfide (DMS) oxidizing ability. The strains S3, W4, W7
were selected due to its best Dimethyl sulfide (DMS) removal over 3 days
incubation. In additionally, the concentration of sulfate (SO42-) produced also
supposed that all bacteria has influenced in thiosulfate oxidizing into sulfate (SO42-).
However, its change had not shown drastically. The selected bacteria strains for
identification were based on its results of DMS removal ability (S3, W4, W7). Based
on BLAST analysis of the partial 16S rRNA gene sequence indicated the identity of
strain W7, S3 and W4 as a strain of Microbacterium hominis, Bordetella trematum
and Ochrobactrum intermedium, respectively.
