5 Must Know Facts For Your Next Test

1. Micrococcus luteus is an obligate aerobe, meaning it requires oxygen for growth.
2. It typically forms tetrads or irregular clusters during cell division.
3. This bacterium can be found on human skin and is generally non-pathogenic but can be opportunistic in immunocompromised individuals.
4. Micrococcus luteus has the ability to degrade a variety of organic compounds, making it useful in bioremediation processes.
5. It produces catalase enzyme which helps it to break down hydrogen peroxide into water and oxygen.
