Abstract: The current situations about lubricant biodegradation of mineral lubricant，synthetic lubricant and vegetable lubricant were summarized in this paper，with a highlight of the diversity of lubricant. The main aspect of the lubricant study is focused on the development and evaluation of degradable lubricant. However，environmental friendly treatment of nonrenewable lubricant had less attention in current research. The current work of nonrenewable lubricant is mainly focused on the biodegradability research. However，improving strains and constructing multiple colonies aiming at promoting the ability and efficiency could be more effective ways of lubricant degradation. Developing an efficient，economical and applicative biodegradation technique would be the goal of future research. Synthetic lubricant and vegetable lubricant with high potential of biodegradability would be valuable in research and application.

Key words: nonrenewable lubricant, biodegradation, environment pollution

摘要： 针对润滑油组分多样性的特点，综述了矿物润滑油、合成润滑油、植物油的生物降解研究现状。指出以矿物润滑油为焦点的研究主要集中在可降解润滑油开发与评价方面，缺乏针对废旧润滑油的无害化处理研究。现阶段润滑油生物降解的研究主要围绕在菌种选育、改良等方面。相比之下，构建高效菌群可以避免诱变育种的非定向性和特定菌种的底物单一性，是实现复杂组分润滑油处理的有效方法，以此为基础开发经济适用的生物降解技术将成为今后的研究重点。此外，合成基础油和植物油因具有高度的可生物降解性而具有极大的研究和应用潜力。
