Currently, it is well established that prokaryotes possess cytoskeleton and organelles. This image depicts how magnetic organelles, magnetosomes, are properly partitioned and segregated by a mechanism that relies on the treadmilling of a dedicated cytoskeletal structure, the actin-like MamK fila...

The oxidase test is performed using a reducing agent to detect bacteria’s ability to produce cytochrome c oxidase, an enzyme in the electron transport chain. The reducing agent (N,N,N′,N′-tetramethyl-p-phenylenediamine (TMPD)) changes or produces a purple color as it become oxidized. Pseudom... Read More
Organisms that have the catalase enzyme can detoxify the cell of hydrogen peroxide by converting it to oxygen gas. Bubbles indicate oxygen gas production after the addition of hydrogen peroxide directly to colonies growing on the TSA plate.
The bonded carbons are shown using E. coli, E. faecalis, and C. violaceum. Using BBL's CHROMagar, we were able to show the pi bonds in pink (E. coli) and blue (E. faecalis). Read More
Physarum polycephalum, slime mold, grown in a large perti plate on moist paper towels using oatmeal as the food source. Culture was grown in the dark at room temperature. The paper towel was moistened every day with tap water. After 3 week’s the culture formed sporangia (fruiting bodies). Image ... Read More
