Jayalatha, N.A.Devatha, C.P.2026-02-052019Molecular Biotechnology, 2019, 61, 9, pp. 674-68010736085https://doi.org/10.1007/s12033-019-00193-3https://idr.nitk.ac.in/handle/123456789/24412The use of triclosan (TCS), an antimicrobial agent in consumer product, results in adverse effects on the environment due to its wide usage all over the world. The present study focused on TCS detection and attempted for degradation by biosurfactant produced by Bacillus licheniformis from domestic wastewater in Surathkal region, Karnataka, India. The experimental investigation includes biosurfactant production using crude sunflower oil and detection and degradation of TCS from wastewater by High-Performance Liquid Chromatography (HPLC). Results exhibited that maximum biosurfactant yield (7.8 g/L) was achieved using 1 g/L of glycerol as carbon and 5.5 g/L of ammonium bicarbonate as a nitrogen source. Detection of TCS from domestic wastewater (0.36 mg/L) and degradation was carried out by HPLC. The result discloses that 47.2% and 100% removal of TCS was achieved in 2 h and 16 h for 1:1(v/v) ratio of wastewater and biosurfactant. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.Ammonium bicarbonateAntimicrobial agentsBacteriologyBiomoleculesConsumer productsHigh performance liquid chromatographySunflower oilAdverse effectBacillus licheniformisBio surfactantBiosurfactant productionDomestic wastewaterExperimental investigationsNitrogen sourcesTriclosanSurface active agentsammoniabicarbonatebiosurfactantcarbonglycerolnitrogensunflower oiltriclosanammonium bicarbonatesurfactantArticlebiomasscost effectiveness analysisdegradationemulsionhigh performance liquid chromatographyIndianonhumansurface tensionwaste waterbioremediationchemistryhumanisolation and purificationmetabolismwater pollutantBicarbonatesBiodegradation, EnvironmentalChromatography, High Pressure LiquidGlycerolHumansSunflower OilSurface-Active AgentsWaste WaterWater Pollutants, Chemical
