粒度分析和冷冻蚀刻透射电镜技术表明，中间混合层为胶束、微乳液、乳状液等表面活性剂聚集体共存的结构，其中微乳液结构占主要地位。

The results showed that three kinds of emulsifiers can lower the surface tension of the soy bean protein solution, improve the emulsifying ability. Lecithin and monoglyceride had little effect on the emulsion stability, but sucrose ester can improve the emulsion stability. In the presence of the three kinds of emulsifier the microencapsulation efficiencies were low.

结果表明3种乳化剂均能降低大豆分离蛋白溶液的表面张力，但是卵磷脂、单甘酯对大豆分离蛋白乳状液的稳定性影响不大，而蔗糖酯可以提高大豆分离蛋白乳状液的稳定性，但是三者的存在均使产品的表面油含量增大，微胶囊效率降低。

The results showed that it is more difficult to demulsify for the emulsion of reacted acid and crude oil.

The diagrams indicate that microemulsions can only be formed with a certain Combination of SDS and n-bulanol. A stretch of microemulsion domain changing continuously from direct micelles to bicontinuous structures and to reverse micelles exists when the surfactant to cosurfactant ratio is comparatively low, while the direct micelle area is separated from the reverse micelle area by a mesomorphic medium when the surfactant to cosurfactant ratio is comparatively high.

结果表明：只有当SDS与正丁醇配比在一定范围内才形成微乳状液；当SDS含量较低时，存在由正胶束经过双连续结构到逆胶束的大片微乳状液区；当SDS含量较高时，正胶束和逆胶束微乳状液之间被液晶相所分割。

By 16S rRNA. When it was cultured in MMSW substrate, adding MWFO and SWFO as the carbon source, it could produce crude biodemulsifier of 4 g/L and 3.5 g/L respectively. Compared with biodemulsifier produced by paraffine as the carbon source, both of them could achieve higher demulsification ratio in breaking W/O and O/W model emulsion.
