Study on Biodegradability of a New-style Lube Oil and Improvement in Its Analytical Method

摘要:

运用生物方法研究新型蓖麻油基润滑油的可降解性。通过反复实验, 建立了该润滑油生物降解的基本分析方法, 并与常规分析方法进行了比较。结果表明, 此分析方法准确可靠, 科学逻辑性更严密, 且重复性好。利用筛选的最佳细菌5-11-4混合菌株, 在最适降解条件下, 采用该分析方法, 微生物对该润滑油的降解率达到88.37%, 比常规分析方法高约10.25%左右(常规分析方法的降解率约为78.12%), 体现了两种分析方法之间的差异。

Abstract:

Biodegradability evaluation for caster oil-based lube oil was carried out in the test. By repeated experiments, a basic analytical method for degradability of the lube oil was established and compared with the routine experimental method. The results showed that the basic analytical method was more logical and more reliable, and the experimental data have higher repeatability than the previous ones. Under the optimal culture conditions for the targeting strains 5-11-4, and according to the basic method, the degradation rate of the lube oil arrived to 88.37%, approximate 10.25 percent higher than the corresponding yield obtained by the routine experimental method (the value was about 78.12%), indicating the difference between the basic analytical method and the routine experimental one.
