World-Class CDMO Services

Experience To Solve Your Microbiome Challenges

Arranta Bio provides contract development and manufacturing services to pioneering innovators working on new therapies targeting diseases linked to the human microbiome.

Arranta Bio is delivering on its vision to build the best-in-class microbiome contract development and manufacturing organization (CDMO) through our merger with a 10-year veteran CDMO, Captozyme, and the establishment of a commercial-ready manufacturing facility.

Our aim is to support the pioneers in the development of healthcare therapies based on live biotherapeutic products (LBPs) targeting gut health and microbiome-related diseases by providing development and manufacturing services that bring effective treatments to the market and patients in need.

Over a 10-year period, Captozyme produced over 125 species and amassed a deep understanding of the manufacturing needs for live biopharmaceuticals, whether that be obligate, facultative or microaerophilic organisms.
