Rare Earth Element Biomining from the Great Salt Lake Brine Using Engineered E. Coli

This data describes rare earth element adsorption onto E. coli cells engineered to express a lanthanide binding tag (LBT). We used a Great Salt Lake synthetic solution as the background matrix with Tb added to 1-10,000 ppb, concentrations much lower than the competing ions present. Our results showed that Tb binds to LBT, even in the presence of high concentrations of competing metals. We also tested REE adsorption at elevated temperatures (up to 100 degrees Celsius), and observed that Tb adsorption increases with temperature of to 70 degrees Celsius, and then remains constant until 100 degrees Celsius. Data analyses were performed using an ICP-MS at UCSC.

本数据集描述了稀土元素在经过工程改造、表达镧系金属结合标签（LBT）的大肠杆菌细胞上的吸附情况。实验中以大盐湖合成溶液为背景基质，添加Tb至1-10,000 ppb，浓度远低于现有的竞争离子。研究结果表明，即使在竞争金属的高浓度存在下，Tb也能与LBT结合。此外，我们还测试了稀土元素在升高温度（高达100摄氏度）条件下的吸附情况，观察到Tb的吸附量在70摄氏度时达到峰值，并在此温度下保持恒定，直至100摄氏度。数据分析采用了UCSC的ICP-MS进行。
