Successful commercialization of NGH is curtailed by lack of efficient and safe technology for generation, dissociation, storage and transportation. The present work studied the influence of environment compatible biosurfactant on gas hydrate formation. Biosurfactant was produced by Pseudomonas aeruginosa strain A11 and was characterized as rhamnolipids. Purified rhamnolipids reduced the surface tension of water from 72 mN/m to 36 mN/m with Critical Micelle Concentration (CMC) of 70 mg/l. Use of 1000 ppm rhamnolipids solution in C type silica gel bed system increased methane hydrate formation rate by 42.97% and reduced the induction time of hydrate formation by 22.63% as compared to water saturated C type silica gel. Presence of rhamnolipids also shifted methane hydrate formation temperature to higher values relative to the system without biosurfactant. Results from thermodynamic and kinetic studies suggest that rhamnolipids can be applied as environment friendly methane hydrate promoter.</p>1 aArora, Amit1 aCameotra, Swaranjit, Singh1 aKumar, Rajnish1 aBalomajumder, Chandrajit1 aSingh, Anil, Kumar1 aSanthakumari, B.1 aKumar, Pushpendra1 aLaik, Sukumar  uhttps://library.ncl.res.in/content/biosurfactant-promoter-methane-hydrate-formation-thermodynamic-and-kinetic-studies-1
