How do microbes make and consume elemental S(0)?
Phototrophic and chemolithotrophic S-oxidizing microorganisms can produce elemental sulfur S(0) as part of their metabolisms. We are interested in the metabolic and genetic mechanisms of S(0) formation and dissolution in:
a model S-oxidizing phototroph, Chlorobaculum tepidum, in collaboration with Tom Hanson (see abstract).
communities of chemolithotrophic S-oxidizing biofilms in the Frasassi Caves, in collaboration with Jenn Macalady (see abstract).
