👉 Microchrysosphaera is a bacterium that is commonly found in soil, including compost and manure, as well as on the surface of plants. It can cause disease in plants, particularly in those with weak immune systems or where it is not properly treated. Microchrysosphaera is an example of a commensal bacteria, meaning it lives alongside other microorganisms in an ecosystem, contributing to nutrient cycling and maintaining soil health.
