Ch. R-7 Isolation and Characterization of Novel Halophilic Anaerobic Bacteria from Oil Field Brines

It is very common that COD and NH3 are found in Produced Water with elevated concentration. One proven technology that is capable in removing organic substances and nutrients, is Horizontal Subsurface Flow Constructed Wetland (HSCW). Based on characterization of produced water from one oil field in Indonesia, it was shown that COD and NH3 were found to exceed the threshold limit stated in Ministry of Environmental Decree no. 19 Year 2010. Modified HSCWs were developed in order to treat produced water containing high concentration of COD and NH3 and allowing anaerobic process to occur in the reactor. The HSCWs were planted by three different species; they were Sagittaria palaefolia (Jasmine Water), Scirpus grossus (Mensiang), and Typha latifolia (Walingi). Organic loading rates (OLRs) to the HSCWs reactor were varied from 7.2 to 72 gr COD/m2.day. It was found that HSCW planted with Typha latifolia had the highest removal efficiency for both COD and NH3 when the OLR was set at 14.4 gr COD/m2.day. Anaerobic bacteria were found in high number indicating that these bacteria involved actively in removing pollutants containing in produced water. However, further microbiology study should be performed in order to determine the role of anaerobic bacteria.

Isolation And Characterization

An asporogenous, gram-positive, anaerobic bacterium was isolated in pure culture from the brains of numerous dead and moribund striped mullet (Mugil cephalus) from Biscayne Bay, Florida. Biochemical characterization confirmed that it was a new species and has been named Eubacterium tarantellus (ATCC 29255). All isolates produced lecithinase and deoxyribonuclease, were beta hemolytic, but only weakly fermented selected carbohydrates. This anaerobe was pathogenic for channel catfish (Ictalurus punctatus) but not for white mice or guinea pigs.More recently E. tarantellus has been isolated from 10 additional fish species. This and other anaerobic bacteria may be significant pathogens of estuarine fish. Key words: Anaerobic bacteria, Eubacterium, Mugil cephalus, and fish diseases.

Petroleum Contaminated Soil

A strain ofPseudomonas stutzerinamed LH42 was isolated from the petroleum-contaminated soil collected from Liaohe Oil Field, Liaoning, China. The strain was capable of degrading dibenzothiophene (DBT). The bacterium was motile, rod-shaped, and grew optimally at 30°C and initial pH of 7.0. The morphological, physiological characterizations and analysis based on 16S rRNA sequence indicated that this strain was most closely related toPseudomonas stutzeri(>99% similarity in gene sequence). Coal biodesulfurization of this strain was processed. And a total sulfur removal of 41.5% and organic sulfur removal of 92.9% was obtained within 25 days. Scanning electron microscope (SEM) analysis revealed that the strain was closely attached on the coal surface and the coal was markedly etched.
