As population and fuel demand increase, many events of oil spills in the environment have been recorded. In order to restore these environments, several techniques have been proposed in the literature, especially in the field of bioremediation, with their main advantage being a low impact on the environment. In this work, poly(butylene succinate) microspheres containing urea were produced, representing a source of controlled release of nitrogen to the environment, promoting the biostimulation of the native microbiota of contaminated sites. Experiments were conducted based on the biostimulation of Pseudomonas aeruginosa and assessed the growth of the culture, the controlled release of urea, the substrate consumption and the toxicity of the microspheres using Artemia salina.

靶向生物修复的聚（丁二酸丁二醇酯）-尿素微球的制备及毒理学评价

随着人口和燃料需求的增加，环境中发生了许多漏油事件。为了恢复这些环境，文献中提出了几种技术，特别是在生物修复领域，它们的主要优点是对环境的影响小。在这项工作中，生产了含有尿素的聚（丁二酸丁二醇酯）微球，作为氮向环境受控释放的来源，促进受污染场地的天然微生物群的生物刺激。基于铜绿假单胞菌的生物刺激进行了实验，并使用卤虫评估了培养物的生长、尿素的控释、底物消耗和微球的毒性。
