Abstract | Microbial reduction of arsenate [As(V)] plays an important role in arsenic (As) mobilization in aqueous environments. In this study, we investigated reduction of arsenate by different bacterial isolates such as OSBH1 (GU329913), OSBH2 (GU329914), OSBH3 (GU329915), OSBH4 (GU329916) and OSBH5 (GU329917), isolated from the oil sludge of a sewage treatment plant operated by the China Petroleum Refinery Company in Kaohsiung, southern Taiwan. Bacterial strains of pure culture were identified by 16S rRNA analysis (≥99 % nucleotide similarity). Morphological and 16S rRNA analysis show that the isolate OSBH1 is similar to E. coli, OSBH2 is similar to P. stutzeri, OSBH3 is similar to P. putida, OSBH4 is similar to P. aeruginosa, and OSBH5 is similar to B. Cereus. The As(V) was transformed to As(III) in the presence of isolates OSBH2 and OSBH5 by a detoxification process. The potential reduction rates of As(V) were higher in the presence of isolate OSBH5 compared to the isolate OSBH2. The microbial growth (cell/mL) of isolate OSBH5 was significantly higher in culture medium compared to OSBH2. The bacterial isolates such as OSBH1, OSBH3 and OSBH4 were found to be incapable of transforming the As(V). It is concluded that the activity of the oil-degrading bacterial isolates described in this work contributes to the mobilization of As in the more toxic As(III) form that affects biotic life. |
