This work is a first approach to demonstrate the viability of a quantitative biotechnological removal of choline chloride from aqueous effluents. Despite the much vaunted biocompatibility of this ammonium-based ionic liquid, it was demonstrated (both by an ad-hoc F test recommended by the Organization for Economic Co-operation and Development and flask assays) that different microorganisms able to degrade persistent chemicals were not able to metabolize it. Only a halophilic bacterium, recently isolated in our research group (Halomonas sp.), exhibits the enzymatic mechanism to catalyze the cleavage of the ionic liquid cation. The biotechnological process was optimized by carefully cherry-picking the carbon source and proposing an adaptation strategy. In this way, a complete choline removal was attained in less than 24 h when the surfactant Tween 80 was added to the ionic liquid-containing aqueous effluent.

从生物技术的角度测试真正的胆碱离子液体生物相容性

这项工作是证明从废水中定量生物技术去除氯化胆碱的可行性的第一种方法。尽管这种基于铵的离子液体具有很大的生物相容性，但已证明（通过经济合作与发展组织推荐的临时F试验和烧瓶试验），能够降解持久性化学物质的不同微生物并没有能够代谢它。在我们的研究小组中仅分离出了一种嗜盐细菌（Halomonas）显示出催化离子液体阳离子裂解的酶机制。通过仔细挑选碳源并提出适应策略来优化生物技术过程。以此方式，当将表面活性剂吐温80加入到含离子液体的含水流出物中时，在不到24小时内完全除去了胆碱。
