Biotherapeutic production
From microbial to mammalian production platforms, Eurofins CDMO provides comprehensive solutions to cater the diverse needs of our clients in the biopharmaceutical industry from early development to phase 2 clinical studies.

Microbial production capabilities
- High-efficiency fermentation: from process development in parallel bioreactor systems to stainless steel and single-use fermenters at various scales, we can support small-scale productions as well as large-scale manufacturing using batch or fed-batch processes.
- Targeted expression: next to cytosolic protein production, we can engineer bacterial systems to direct protein expression to the periplasmic space, facilitating protein folding and purification.
- Scalable manufacturing: based on a good understanding of critical process parameters, we develop processes with commercial manufacturing as a goal.
- Comprehensive downstream processing: our DSP capabilities include centrifugation, high pressure cell disruption, refolding of inclusion bodies, precipitation, chromatography and filtration (TFF, UF/DF and end filtration)
- Regulatory compliance
Mammalian production capabilities
Our mammalian cell culture facilities offer:
- Flexible cell culture systems: our platform supports diverse cultivation methods, i.e., fed-batch and perfusion processes, across wide-range of development and pilot scales. From small-scale parallel testing (100-250 mL) and bench scale (5-10L) capabilities to large-scale pilot manufacturing (50-200L), our upstream team can deliver scalable process for maximizing production of diverse array of biologics. With various expertise in improving harvest techniques, such as depth and sterile filtration, we can effectively clarify cell culture from cell-based debris and ensure consistent product quality
- Customized DSP solutions: next to our broad range of DSP capabilities, we focus for mammalian cell line projects especially on viral safety by including viral clearance steps in the manufacturing process and coordinating viral clearance studies.
- Robust analytical development and bioassay capabilities for advanced evaluation and characterization of critical quality attributes
- Robust and scalable process development and optimization
- Full GMP compliance: our facilities and operations are fully compliant with GMP standard, ensuring the highest levels of quality and regulatory adherence


Complexity in the spotlight: manufacturing phage lysins
Phage lysins, also known as endolysins, are enzymes produced by bacteriophages to facilitate the release of newly formed phage particles from bacterial hosts. In medicine, phage lysins are being explored for their potential therapeutic applications. This class of proteins was shown in various animal models to be a promising alternative or complement to traditional antibiotics and to combat the increasing threat of antibiotic-resistant bacteria.
It is important to rely on a CDMO with a solid experience in this field, as producing endolysins recombinantly presents different challenges. To name some:
- Toxicity of the target protein to the host cell
- Formation of inclusion bodies and aggregates
- Protein folding and stability to maintain enzymatic activity
- Purification challenges
We successfully supported several endolysin projects from early development to clinical manufacturing.
