[HTML][HTML] Demulsifying properties of extracellular products and cells of Pseudomonas aeruginosa MSJ isolated from petroleum-contaminated soil
JOPA Coutinho, MPS Silva, PM Moraes… - Bioresource …, 2013 - Elsevier
A strain of Pseudomonas aeruginosa isolated from a site contaminated with refined oil
products exhibited demulsification capabilities against Tween 80–Span 80 stabilized oil-in-
water (O/W), Tween 80-stabilized water-in-oil (W/O) model emulsions (kerosene–water), and
an industrial emulsion (Daido Dairoll PA-5A). GC–MS analysis confirmed the presence of
fatty acids and carbohydrates in the extracellular biodemulsifier. The demulsifying activity of
cells and culture supernatants was favored by growth in media containing 1% diesel oil …
