Biodegradation of Linear Alkylbenzene Sulfonate (LAS) by Immobilized Pseudomonas sp
Anionic surfactants are the most widely exploited chemical surfactants, which are being incorporated into majority of detergents and cleaning products used for household and industrial applications. Linear alkylbenzene sulfonates (LAS) is one of the major xenobiotic anionic surfactants. Biodegradation is an effective process to reduce the amount of surfactants released in the environment. In th...
متن کاملExtant Biodegradation Testing With Linear Alkylbenzene Sulfonate in Laboratory and Field Activated Sludge Systems
Two 1-L porous pot (65 μ stainless steel mesh) reactors were fed synthetic wastewater with a COD of 200 mg/L including 2 mg/L linear alkyl benzene sulfonate (LAS) to evaluate the influence of specific operating conditions (i.e, hydraulic retention time, HRT, and solids retention time, SRT) on the measured rate of LAS biodegradation. The reactors were operated in parallel under a constant SRT of...
متن کاملBiodegradation of linear alkylbenzene sulfonate by a two-member facultative anaerobic bacterial consortium
A bacterial consortium capable of degrading the linear alkylbenzene sulfonate (LAS) was isolated from the wastewater treatment plant. The bacterial consortium consisted of two members, Pantoea agglomerans and Serratia odorifera 2. Cells were grown evenly together in a minimal medium (M9) and nutrient broth (NB). The bacterial consortium was able to grow in the minimal medium containing LAS as t...
متن کاملHistopathological changes of gill, liver and kidney in Caspian kutum exposed to Linear Alkylbenzene Sulfonate
The histopathological effects of Linear Alkylbenzene Sulfonate on the gill, liver and kidney tissues of the Caspian kutum, Rutilus frisii kutum were studied. The fish were exposed to three sublethal concentrations of anionic detergent, Linear Alkylbenzene Sulfonate (LAS) for short term intervals (192 h). Gill, liver and kidney samples were collected after 192 h of exposure to LAS and lesions we...
