Abstract

The potential of bacterial magnetic nanoparticles and magnetotactic bacteria has increased significantly in wastewater treatment. Magnetotactic bacteria and their magnetosomes exhibit unique magnetic and structural properties that facilitate the efficient removal of pollutants, including heavy metals, dyes, pesticides, and radionuclides. Unlike chemically synthesized nanoparticles, bacterial magnetosomes are biocompatible, recyclable, and can be manipulated using external magnetic fields, making them suitable for repeated use in treatment systems. This review examines the current advancements in the cultivation, large-scale manufacture, and functionalization of magnetotactic bacteria and magnetosomes, as well as their extensive applications in environmental and industrial sectors. Advanced analytical techniques play a crucial role in confirming the physical, chemical, and magnetic stability of these materials. Together, these properties make magnetotactic bacteria and their magnetosomes promising tools for eco-friendly and cost-effective wastewater treatment.

细菌磁性纳米颗粒和趋磁细菌对废水污染物的生物修复研究进展。

细菌磁性纳米颗粒和趋磁细菌在废水处理中的潜力显著增加。趋磁细菌及其磁小体表现出独特的磁性和结构特性，有助于有效去除污染物，包括重金属、染料、农药和放射性核素。与化学合成的纳米颗粒不同，细菌磁小体具有生物相容性、可回收性，并且可以使用外部磁场进行操作，这使得它们适合在处理系统中重复使用。本文综述了趋磁细菌和磁小体的培养、规模化制造、功能化及其在环境和工业领域的广泛应用。先进的分析技术在确认这些材料的物理、化学和磁稳定性方面起着至关重要的作用。总之，这些特性使趋磁细菌和它们的磁小体成为环保和经济有效的废水处理工具。

期刊介绍： World Journal of Microbiology and Biotechnology publishes research papers and review articles on all aspects of Microbiology and Microbial Biotechnology. Since its foundation, the Journal has provided a forum for research work directed toward finding microbiological and biotechnological solutions to global problems. As many of these problems, including crop productivity, public health and waste management, have major impacts in the developing world, the Journal especially reports on advances for and from developing regions. Some topics are not within the scope of the Journal. Please do not submit your manuscript if it falls into one of the following categories: · Virology · Simple isolation of microbes from local sources · Simple descriptions of an environment or reports on a procedure · Veterinary, agricultural and clinical topics in which the main focus is not on a microorganism · Data reporting on host response to microbes · Optimization of a procedure · Description of the biological effects of not fully identified compounds or undefined extracts of natural origin · Data on not fully purified enzymes or procedures in which they are applied All articles published in the Journal are independently refereed.
