The Horsfall group is engineering bacteria to recover metals from spent lithium ion batteries (LiBs) once reuse is no longer possible. By using the new tools and techniques provided by advances in biology we will engineer microbes with the ability to selectively recover metals in the form of nanoparticles adding value to the recovery process. Desulfovibrio alaskensis can recover a variety of metals through the production of nanoparticles but it cannot discriminate between Co and Ni, both of which are likely to be present in battery leachates. Therefore, this PhD project will investigate the selective recovery of Ni through engineering of D. alaskensis. This project will also investigate the recovery of two other important metals in LiBs, Al and Li, using Pseudomonas species. Furthermore, the elemental composition and physicochemical properties of biogenic nanoparticles are known to differ depending on the bacterial species and conditions used. Thus, the production of biogenic Ni, Li and Al nanoparticles will be studied under varying factors (e.g. aerobic/anaerobic, media composition, temperature).This project will examine native bacterial metal resistance systems, their potential for genetic manipulation and opportunities for their application. This may involve the characterisation of promoters and ribosomal binding sites with reporter genes, the optimisation of proteins in the metal nanoparticle synthesis pathway and investigation of the resultant effects on the metal resistance exhibited by the organism. The identification of relevant molecules for the selective recovery of Ni, Al and Li will contribute to the development of a of bio-based system for the recovery of metals. The project offers training in molecular biology, synthetic biology, biochemistry and nanotechnology. The work in this project will provide the necessary tools and knowledge needed to improve upon current metal biorecovery yields.

Horsfall 团队正在改造细菌，以便在无法再利用的废旧锂离子电池 (LiB) 中回收金属。通过使用生物学进步提供的新工具和技术，我们将设计微生物，使其能够选择性地以纳米粒子的形式回收金属，从而为回收过程增加价值。阿拉斯加脱硫弧菌可以通过生产纳米颗粒回收多种金属，但它无法区分电池渗滤液中可能存在的钴和镍。因此，本博士项目将研究通过阿拉斯加石斛的工程选择性回收镍。该项目还将研究利用假单胞菌物种回收锂硼中的其他两种重要金属：铝和锂。此外，已知生物纳米粒子的元素组成和物理化学性质根据所使用的细菌种类和条件而有所不同。因此，将在不同因素（例如需氧/厌氧、培养基成分、温度）下研究生物镍、锂和铝纳米粒子的生产。该项目将研究天然细菌金属抗性系统、其遗传操纵的潜力及其应用机会。这可能涉及启动子和核糖体与报告基因结合位点的表征、金属纳米颗粒合成途径中蛋白质的优化以及对生物体表现出的金属抗性的最终影响的研究。识别选择性回收镍、铝和锂的相关分子将有助于开发用于回收金属的生物基系统。该项目提供分子生物学、合成生物学、生物化学和纳米技术方面的培训。该项目的工作将提供提高当前金属生物回收率所需的必要工具和知识。
