magnetotactic bacteria

dennis.bazylinski@unlv.edu

The Bazylinski lab studies the magnetosome biomineralization in magnetotactic bacteria (MTB). We are interested in physiological aspects of these bacteria in marine habitats. A second research focus is the evolution of the magnetosome island on the basis of different MTB strains and the functional analysis of the mam genes.
