Characterization of natural microcosms of estuarine magnetotactic bacteria
To date, no complete study of magnetotactic bacteria’s (MTB) natural microcosms in estuarine or tropical environments has been reported. Besides, almost all the studies around magnetotactic bacteria have been based on fresh waters away from the Equator. In this work, we focused the experimental regi...
