“…Till now, pure substrates such as glucose and hydrocarbons like hexadecane, palm oil, olive oil etc have been used for biosurfactant production [8,9]. Di-rhamnolipid biosurfactant produced from distillery wastewater as nocost complete nutrient medium, by Pseudomonas aeruginosa BS2 is highly effi cient in regard to its surface-active properties.…”

An unconventional nutrient medium, distillery spent wash ((1:3) diluted) was used to produce di-rhamnolipid biosurfactant by Pseudomonas aeruginosa strain BS2. This research further assessed the potential of the biosurfactant as a washing agent for metal removal from multimetal contaminated soil (Cr-940 ppm; Pb-900 ppm; Cd-430 ppm; Ni-880 ppm; Cu-480 ppm). Out of the treatments of contaminated soil with tap water and rhamnolipid biosurfactant, the latter was found to be potent in mobilization of metal and decontamination of contaminated soil. Within 36 hours of leaching study, di-rhamnolipid as compared to tap water facilitated 13 folds higher removal of Cr from the heavy metal spiked soil whereas removal of Pb and Cu was 9-10 and 14 folds higher respectively. Leaching of Cd and Ni was 25 folds higher from the spiked soil. This shows that leaching behavior of biosurfactant was different for different metals. The use of wastewater for production of biosurfactant and its effi cient use in metal removal make it a strong applicant for bioremediation.

“…For the extraction of biosurfactant compounds, 50 ml of chloroform-methanol (2:1, v/v) was added to 500 mg of the dry product and incubated in a rotatory shaker at 250 rpm, 30ºC for 15 minutes. The mixture was filtrated using a 0.45 µm Millipore membrane (Thaniyavarn et al 2006). The filtrate was lyophilized, weighed for quantification and then used for antimicrobial activity tests.…”

“…The Pseudomonas genus is a known producer of biosurfactants, particularly rhamnolipids [10,41,64]. Biosurfactant-producing Pseudomonas strains have been isolated from diverse environments: oilcontaminated soils [41,57], marine water [68], uncontaminated freshwater [34], and even air [60].…”
