Abstract:

The motility of bacteria is a key factor that affects their survival and pathogenicity. It also provides an effective model for the synthesis and development of biomimic sports-bodies and micro-robots. Magnetotactic bacteria contain intracellular magnetosomes and are able to respond to an external magnetic field,which then alter their motility behavior under the magnetic field. Currently,this long-range response of living organisms to an external magnetic field has broad applications in the fields of environment,medical treatment,materials,etc. In this review,we focus on the motility of magnetotactic bacteria,and review the latest progress on the characterization and mechanisms of the motility of magnetotactic bacteria,as well as their associated applications. At the end,we address the future directions and challenges of this field.

Key words: magnetotactic bacteria, magnetosome, mechanism of motility, nano-robot
