Definition: Microstrophia is a type of microorganism that can grow in small niches, often found in soil and aquatic environments. These microorganisms primarily live as commensal bacteria or fungi, but they can also be parasitic to other organisms. They are known for their ability to survive without oxygen and are capable of thriving in nutrient-poor conditions. Microstrophia is a fascinating aspect of the microbiome, which plays an essential role in maintaining health and preventing diseases.
