Archaeal membranes differ from bacterial membranes because the phospholipids in archaeal membranes are linked with ether linkages and not ester linkages. While bacterial cell membranes are often bilayers, many archaeal membranes are monolayers.

Phospholipids are formed with ester linkages and proteins. These allow the plasma membrane to move fluidly.

Archaea are single-cellular organisms that do not contain nuclei. Archaea different from bacteria because archaeal membranes and cell walls are structurally different.

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.

Archaeal walls are different from bacteria because they do not contain peptidoglycan. Some contain pseudopeptidoglycan or have a cell wall made of glycoproteins or sugars. Some lack a cell wall entirely.
