Peroxisomes were discovered by the Belgian scientist Christian de Duve (1917–2013), who is also credited with the discovery of lysosomes.

Peroxisomes are membrane-bound eukaryotic organelles that produce hydrogen peroxide to break down molecules such as uric acid, amino acids, and fatty acids. They contain the enzyme catalase to degrade hydrogen peroxide, and they function alongside the smooth endoplasmic reticulum (SER) in lipid biosynthesis, while protecting the cytoplasm from oxidative damage through compartmentalization.

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.

Discovery of Peroxisomes

Peroxisomes reproduce by synthesizing peroxin proteins on free ribosomes, importing them from the cytoplasm into existing peroxisomes, and then dividing through a process similar to binary fission.

Peroxisome Formation and Division

Glyoxysomes are modified peroxisomes found in yeasts and plant cells that perform specialized metabolic functions, including the production of sugar molecules.

Glyoxysomes

Glycosomes are modified peroxisomes produced by certain trypanosomes, which are pathogenic protozoans that cause Chagas disease and African sleeping sickness.
