Abstract
Formation of oil-water emulsions during bacterial growth on hydrocarbons is often attributed to biosurfactants. Here we report the ability of certain intact bacterial cells to stabilize oil-in-water and water-in-oil emulsions without changing the interfacial tension, by inhibition of droplet coalescence as observed in emulsion stabilization by solid particles like silica.
摘要
细菌在烃类物质上生长期间形成油水乳液通常归因于生物表面活性剂。在此，我们报告某些完整细菌细胞能够在不改变界面张力的情况下稳定水包油和油包水乳液，其方式是通过抑制液滴聚结，如同二氧化硅等固体颗粒在乳液稳定化过程中所观察到的那样。
