Methylobacterium fujisawaense is a facultatively anaerobic, Gram-negative, rod-shaped bacteria. It is catalase-positive and oxidase-negative. It produces pink-pigment on microbiological agar media (TSA and R2A, etc.). This bacteria is facultatively methylotrophic and is widely distributed in nature. They can be isolated from soil and on occasion freshwater environments, including drinking water.

Commonly, M. fujisawaense bacteria is not established as pathogenic; however, rarely it may cause human infection/disease, mostly in immunocompromised patients.
