Due to their non-toxic nature, biodegradability and production from renewable resources, research has shown an increasing interest in the use of biosurfactants in a wide variety of applications. This paper reviews the characterization of rhamnolipid and sophorolipid biosurfactants based on their hydrophilicity/hydrophobicity and their ability to form microemulsions with a range of oils without additives. The use of the biosurfactants in applications such as detergency and vegetable oil extraction for biodiesel application is also discussed. Rhamnolipid was found to be a hydrophilic surfactant while sophorolipid was found to be very hydrophobic. Therefore, rhamnolipid and sophorolipid biosurfactants in mixtures showed robust performance in these applications.

由于其无毒性质、生物可降解性以及可再生资源生产特性，研究表明人们对生物表面活性剂在广泛应用中的使用兴趣日益浓厚。本文基于鼠李糖脂和槐糖脂生物表面活性剂的亲水性/疏水性以及它们在无添加剂情况下与一系列油形成微乳液的能力，对其特性进行了综述。还讨论了生物表面活性剂在诸如洗涤以及用于生物柴油应用的植物油提取等应用中的使用情况。发现鼠李糖脂是一种亲水性表面活性剂，而槐糖脂则非常疏水。因此，混合物中的鼠李糖脂和槐糖脂生物表面活性剂在这些应用中表现出强大的性能。
