摘要

本实验优化了菌株Dietzia sp. DQ12-45-1b生物表面活性剂的提取和检测方法，并研究了菌株在正十六烷上生长不同培养时间的生物表面活性剂产物。乙酸乙酯为最佳提取溶剂，代谢物回收率最高。采用正己烷:氨:异丙醇= 2:1:4 (V:V:V)的混合物作为薄层色谱分析的最佳溶剂体系。菌株DQ12-45-1b产生糖脂类生物表面活性剂，培养液中生物表面活性剂浓度与培养时间呈正相关。乳化十六烷层与水介质中粗提物的含量比为4.16:1。在乳化十六烷层中检测到糖脂，但在水相中未检测到糖脂。图5，表1，文献15

O658Detection of Metabolites from n -Hexadecane Degradation by Strain Dietzia sp. DQ12-45-1b: O658Detection of Metabolites from n -Hexadecane Degradation by Strain Dietzia sp. DQ12-45-1b

This experiment optimized the extraction and detection methods of biosurfactant produced by the strain Dietzia sp. DQ12-45-1b, and studied biosurfactant products of the strain growing on n-hexadecane for different cultural time. Ethyl acetate was the best extraction solvent with the highest metabolite recovery effi cient. The mixture of hexane : ammonia : isopropanol = 2:1:4 (V:V:V) was used as the best solvent system in thin layer chromatography analysis. The strain DQ12-45-1b produced glycolipid biosurfactant, with the biosurfactant concentration of the culture broth positively correlated with the incubation time. The content ratio of crude extracts in emulsifi ed hexadecane layer and aqueous medium was 4.16:1. A glycolipid was detected in the emulsifi ed hexadecane layer but not in aqueous phase.
