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 کاملBiodegradation of linear alkylbenzene sulfonates in sulfate-leached soil mesocosms.
Aromatic sulfonates (R-SO(3)(-)) can be used as sulfur sources by sulfate-starved bacteria in laboratory cultures and the corresponding phenols are excreted from the cells. The present study was conducted to demonstrate whether such desulfonation reactions also occur in sulfate-leached agricultural soil, where desulfonation of organic sulfur compounds may have agronomic importance as a S source...
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 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 کاملScreening test for assessment of ultimate biodegradability: linear alkylbenzene sulfonates.
A relatively simple shake-flask system for determining CO2 evolution was developed to assess the ultimate biodegradability by soil and sewage micro-organisms of chemicals which enter the environment. Linear alkylbenzene sulfonates (LAS) were used as model compounds to evaluate the method and were found to undergo substantial biodegradation in this dilute system. At the 30 mg/liter test concentr...
