“…Bacillus licheniformisis showed the ability to produce biosurfactant which siginificantly lowered the surface tension of various liquids (Karlapudi et al, 2018) A Serratia marcescens BS-03 was isolated from oil contaminated soil among other 42 isolates, and showed the highest emulsification activity with the highest emulsification index (Budsabun, 2015). The ability of oil spreading activity of the isolated microorganisms was tested and it was found that about 42% of the isolated bacteria showed positive oil spreading activity while 18% of them were high spreading activity.…”

Biosurfactant producing bacteria (28 isolates) were isolated from 30 oil contaminated soils and tested for production of biosurfactant by different screening methods. About 75% of the isolated bacteria showed no blood hemolysis and their emulsification index for hexane and xylene ranges from 28-35% and 30-45% respectively. Biosurfactant producing ability was confirmed by other tests where about 40% of isolates showed positive oil spreading activity, hydrocarbon overlay and 67% showed to be positive for drop collapsing test. 16s RNA sequencing of the most active isolates revealed one Stenotrophomonas maltophila, two Bacillus spp. and two Achromobacter spp. Biosurfactants extracted from these isolates showed variable antimicrobial activity against Staphylococcus aureus, E. coli and Pseudomonas aeruginosa. This study demonstrated that the biosurfactants produced by these bacteria could be used in combination with antibiotics for treating bacterial infections. Further study is required for enhancing biosurfactant production by bacterial isolates to be used environmentally for bioremediation of oil contaminated soils.

“…Since 1970, more than 5 million tons of oil spills are reported by International Tanker Owners Pollution Federation affecting serious health problems. Petroleum oil is a non-volatile and low molecular compound (Budsabun, 2015). Biosurfactants are surface active compounds produced by different bacteria.…”

Biosurfactants are microbial amphiphilic compounds which can reduce surface tension between aqueous and hydrocarbon mixtures. Bacterial strains isolated from petroleum contaminated soil of various motor workshops were characterized morphologically and biochemically. Biosurfactant producing ability of the strains was determined and their emulsification activity was screened against different oils. All the selected bacterial strains showed enhanced biosurfactants production with yeast extract as nitrogen source and glucose as carbon source at optimized conditions. These strains also exhibited multiple metal and antibiotics resistance. Isolated biosurfactants of three most promising strains SF-1, SF-4 and SM-1 were extracted by solvent extraction and subjected to TLC technique. The technique indicates the glycolipid nature of the compounds and presence of rhamnose sugar, which was further confirmed by FT-IR analysis. 16srRNA analysis revealed that SF-1 and SM-1 had close resemblance with Pseudomonas sp. while SF-4 showed homology with Enterobacter sp. Isolation and screening of biosurfactant producing strains from petroleum polluted places proved to be a quick and effective means to find bacterial strains with possible industrial uses.
