摘要

游离或固定形式的微生物细胞可用于金属离子、有机和无机外源物或生物活性化合物的预浓缩或去除。对这些细胞进行磁改性,可以制备磁性吸附剂,在存在外部磁场的情况下,可以很容易地在难以处理的样品中操作,例如悬浮液。本文介绍了磁性修饰微生物细胞的典型例子,以及它们在有机外源物和重金属离子分离方面的应用前景。

Magnetically modified microbial cells: A new type of magnetic adsorbents

Microbial cells, either in free or immobilized form, can be used for the preconcentration or removal of metal ions, organic and inorganic xenobiotics or biologically active compounds. Magnetic modification of these cells enables to prepare magnetic adsorbents that can be easily manipulated in difficult-to-handle samples, such as suspensions, in the presence of external magnetic field. In this review, typical examples of magnetic modifications of microbial cells are presented, as well as their possible applications for the separation of organic xenobiotics and heavy metal ions.
