چکیده انگلیسی
The aim of the study was to characterize and optimize the growth media for biosurfactant production from Serratia rubidaea SNAU02 isolated from hydrocarbon-contaminated soil from Cuddalore district, Tamilnadu, India. The biosurfactant produced by S. rubidaea SNAU02, was able to reduce the surface tension to 34.4 mN mâ1 in MSM medium. The biosurfactant was characterized by FT-IR and GC-MS analysis. The GC-MS analysis shows that dirhamnolipid was detected in abundance as predominant congener than monorhamnolipid. The response surface methodology (RSM) -central composite design (CCD) was performed to optimize the media for biosurfactant production. The maximum emulsification index was obtained under the optimal condition of 29.31 g Lâ1 mannitol; 2.06 g Lâ1 yeast extract, medium pH 6.97 and 5.69 g Lâ1 NaCl. The biosurfactant produced by S. rubidaea recovered 92% of used engine oil adsorbed to a sand sample, suggested the potential application in microbial enhanced oil recovery and bioremediation.
