Two Nitrosospira strains were considerably more sensitive to LAS than two Nitrosomonas strains were. Research on biodegradation of LAS with 100 ppm, 400 ppm, 700 ppm, 1000 ppm and 1500 victor.leon@ua.es A study has been made of the aerobic biodegradation of linear … Linear alkylbenzene sulfonate (LAS), a biodegradable surfactant, is manufactured from sulfonation of linear alkyl benzene. Viable and total bacteria were determined during linear alkylbenzene sulfonate (LAS) degradation in coastal seawater. The concentration of LAS based on dry matter typically increases during anaerobic stabilization due to transformation of easily degradable organic matter. Xiuyi Hua, Ming Li, Yulong Su, Deming Dong, Zhiyong Guo, Dapeng Liang, The degradation of linear alkylbenzene sulfonate (LAS) in the presence of light and natural biofilms: The important role of photosynthesis, Journal of Hazardous Materials, 10.1016/j.jhazmat.2012.06.005, 229-230, (450 … Biodegradation of linear alkylbenzene sulfonates and their degradation intermediates in seawater. Linear alkylate sulfonates (LAS) are relatively toxic to fish when tested under static conditions by standard bioassay techniques, the median tolerance limit (TL m) being around 3 mg/liter and 0.6 mg/liter for the C 12 and C 14 homologs, respectively. Linear Alkyl Benzene Sulfonate (LAS) is one of the synthetic surfactants that is widely used. erobic biodegradation of linear alkylbenzene sulfonates and sulfophenylcarboxylic acids for different salinity values by means of continuous assays, Environ Monit Assess, DOI 10.1007/s10661-009-0806-z. of Civil and Construction Engineering, Iowa State University, Ames, IA 50011-3232 2 The Procter and Gamble Company, Cincinnati, OH 45253-8707 ABSTRACT Two 1-L porous pot (65 µ stainless steel mesh) … Linear alkylbenzene sulfonate biodegradation by the consortium and the strains involved was analysed by HPLC, and the extent of degradation was even expressed as the percentage of surfactant disappearance (Fig. Linear alkylbenzene sulfonate (LAS) found in wastewater is removed in the wastewater treatment facilities by sorption and aerobic biodegradation. Gledhill WE. Environmental Monitoring and Assessment 2010 , … 1974;17(0):265-93. Although LAS is biodegradable, its introduction to the environment in big amounts harms water bodies. In this study soil samples were collected from detergent contaminated sites to isolate linear alkylbenzene sulphonate degrading bacteria using mineral salt media supplemented with LAS as sole source of carbon.
Abstract. The concentration of LAS based on dry matter typically increases during anaerobic stabilization due to transformation of easily degradable organic matter. Linear alkylbenzene sulfonate (LAS) found in wastewater is removed in the wastewater treatment facilities by sorption and aerobic biodegradation. Dialkyltetralin sulfonate (OATS) and single methyl-branched isomers of linear alkylbenzene sulfonate (iso-LAS) are coproducts that together can range from 1 to 10% of commercial LAS depending on the manufacturing process.
Branched chain ABS biodegrades very slowly and therefore contributes to polluting lakes and streams by forming relatively stable foams. Kinetics of methane production and biodegradation of linear alkylbenzene sulfonate from laundry wastewater.
