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 کاملProbabilistic risk assessment for linear alkylbenzene sulfonate (LAS) in sewage sludge used on agricultural soil.
Deterministic and probabilistic risk assessments were developed for commercial LAS in agricultural soil amended with sewage sludge. The procedure done according to ILSI Europe's Conceptual Framework [Schowanek, D., Carr, R., David, H., Douben, P., Hall, J., Kirchmann, H., Patria, L., Sequi, P., Smith, S., Webb, S.F., 2004. A risk-based methodology for deriving quality standards for organic cont...
متن کاملHalf maximal effective concentration (EC50 of the Linear Alkylbenzene Sulfonate (LAS) on the green marine microalgae Nannochloropsis oculata
In the present study, half maximal effective concentration (EC50) of the Linear Alkylbenzene Sulfonate on microalgae Nannochloropsis oculata were investigated. The experiment was carried out with seven treatments (six main treatments and one control) with three replications in 25 ºC and pH of 6.9 for 72 hours on July 2017. The concentration of linear alkyl benzene sulfonate in first to six trea...
متن کاملComparison Between Acidogenic and Methanogenic Inhibition Caused by Linear Alkylbenzene-Sulfonate (LAS)
The anaerobic mixed microbiote may be inhibited through different mechanisms: inhibition by product or substrate, by the physical characteristics of the medium (pH or temperature), and by inhibitory substances, organic or inorganic. Biological activity tests have been the most widely used, of different experimental procedures known, to evaluate the toxicity of various compounds in anaerobic pro...
متن کاملOptimization of linear alkylbenzene sulfonate (LAS) degradation in UASB reactors by varying bioavailability of LAS, hydraulic retention time and specific organic load rate.
Degradation of linear alkylbenzene sulfonate (LAS) in UASB reactors was optimized by varying the bioavailability of LAS based on the concentration of biomass in the system (1.3-16 g TS/L), the hydraulic retention time (HRT), which was operated at 6, 35 or 80 h, and the concentration of co-substrates as specific organic loading rates (SOLR) ranging from 0.03-0.18 g COD/g TVS.d. The highest degra...
