| Summary: | (sophorolipid-producing), and Bacillus subtilis ATCC 21332 (surfactin-producing) were compared to a control of 9027 (rhamnolipid-producing), Candida bombicola ATCC 22214 by Rhodococcus strain H13-A and a commonly-used synthetic compared to their parent compounds. In the second study, the concentrations in the presence of surfactants; the increase conditions. distilled-deionized water and the crude oil. Using a distilled-deionized water. The experimental design was effects of four biosurfactants on the solubility of petroleum experiment, each reactor contained a surfactant solution and experiments. In the first, a biological surfactant produced H13-A (glycolipid-producing), Pseudomonas aeruginosa ATCC moderately increased the solubilities of the other saturates. negligible increase in solubility under these laboratory Neither the Candida nor the Bacillus solutions produced any organic phase into aqueous solution. In the batch-reactor sampled to determine the water-accommodated fraction (WAF). saturated hydrocarbons were compared. Rhodococcus species significant for the highly-substituted aromatics, when significant increases in their aqueous-plus-micellar-phase similar that of the first study. The Pseudomonas aeruginosa solubility of the low-molecular-weight compounds, but only surfactant, Tween-80 (polyoxyethylene sorbitan monooleate), surfactant. The enhancement in "solubility" was also more temporal-monitoring scheme, the reactors were sacrificially The phenanthrenes, fluorenes, pyrenes, and chrysenes showed The Rhodococcus treatment significantly enhanced the This research investigation included two similarly-designed transport of polycyclic aromatic hydrocarbons from a complex treatment significantly enhanced the solubility of the lower- was greater for the biosurfactant compared to the synthetic weight, higher-weight and branched saturated hydrocarbons. were compared for their effectiveness in enhancing the West Texas Crude oil, while the control reactors contained |
