*Chlorobium* is the genus of green sulfur bacteria. *Chlorobium* uses many types of chlorophyll along with bacteriochlorophyll.

Green sulfur bacteria, *Chlorobium*

Green sulfur bacteria use sulfide (S<sup>2-</sup>) for an oxidation reaction to make green bacteriochlorophyll.

Phototrophic purple and green bacteria can be classified into four main groups based on their ability to use sulfur compounds for oxidation: purple sulfur bacteria, purple non-sulfur bacteria, green sulfur bacteria, and green non-sulfur bacteria.

Microbiology covers the scope and sequence requirements for a single-semester microbiology course for non-majors. The book presents the core concepts of microbiology with a focus on applications for careers in allied health. The pedagogical features of the text make the material interesting and accessible while maintaining the career-application focus and scientific rigor inherent in the subject matter. Microbiology’s art program enhances students’ understanding of concepts through clear and effective illustrations, diagrams, and photographs.

Microbiology is produced through a collaborative publishing agreement between OpenStax and the American Society for Microbiology Press. The book aligns with the curriculum guidelines of the American Society for Microbiology.

This type of purple bacteria can oxidize hydrogen sulfide (H<sub>2</sub>S).

Purple Sulfur Bacteria *Chromatium*

This type of purple bacteria can use hydrogen for oxidation.

Purple non-sulfur bacteria 

Green sulfur bacteria

Green non-sulfur bacteria use other compounds for oxidation such as hydrogen.
