Fermentation Filtration & Clarification Solutions
Improve fermentation performance with filtration solutions designed to support process consistency, contamination control and downstream recovery.
Filtration’s Role in Fermentation Success
Fermentation processes require consistent upstream control and reliable downstream processing to maintain performance at scale. Variability in raw materials, operating conditions, and broth characteristics can influence both process stability and product recovery.
Filtration supports fermentation by enabling contamination control, maintaining consistent input quality, and preparing streams for downstream processing. These steps help reduce variability and support more predictable outcomes across production.
What is fermentation in food and ingredient manufacturing?
Fermentation relies on controlled microbial processes to generate ingredients such as amino acids, enzymes, organic acids and proteins derived from precision fermentation.
As production scales, maintaining consistent conditions becomes increasingly important, as differences in process environment and feed composition can influence both performance and downstream separation.
What challenges impact fermentation processing?
Batch variability
Differences in raw materials and operating conditions can influence broth composition and impact downstream separation.
Contamination risk
Air, utilities, and process inputs can introduce contamination, which may disrupt fermentation and affect product formation.
Scale-up differences
Performance at lab or pilot scale does not always translate directly to production, where system design and operating conditions vary.
Intracellular Vs. Extracellular
Depending on the product of interest being present inside the cell or secreted outside the cell, downstream processing can vary significantly to extract and purify the final product. In addition, presence unknown or undesired metabolites by the microbe can lead to lower yield and quality
Upstream Fermentation Protection
Contamination from air, water, nutrients or utilities can disrupt fermentation processes and impact product formation. Maintaining controlled and consistent upstream conditions is essential to reduce risk and support reliable process performance.
Effective upstream control relies on sterile inputs, consistent utilities and filtration at critical control points across the process.
Sterile Air & Gas Filtration
Air and gas inputs represent critical control points in fermentation. Contaminants introduced through compressed air or tank vents can impact batch performance and lead to process disruption.
Sterile air and gas filtration helps maintain clean gas inputs and supports consistent fermentation conditions.
Our Solutions
Sterile Liquid Filtration
Process liquids used in fermentation can introduce variability if not properly controlled. Filtration helps maintain consistency in media, feeds and water inputs.

Downstream Processing
After fermentation, the broth contains product mixed with cells and suspended solids. The efficiency of downstream processing depends on how effectively these components are separated and prepared for further purification.
Clarification plays a key role in supporting product recovery and consistent downstream processing. Variability in broth conditions can influence filtration performance, particularly at the first clarification step where separation is most sensitive.
Clarification for High Value Ingredients
The performance of clarification can be influenced by broth conditions such as solids content, viscosity, and variability between batches. Stable operation at this stage supports downstream consistency and overall process reliability.
Ceramic membrane systems are used to provide controlled clarification in enclosed, hygienic configurations and to support consistent operation under a range of process conditions.

Our Solutions
Fermentation and clarification process flow
The fermentation process includes upstream preparation, controlled fermentation, biomass separation, clarification, concentration, and final filtration steps. Each stage contributes to overall process performance and final product quality.
Filtration is applied throughout the process to support consistency, manage variability and enable reliable downstream processing. Maintaining consistency across these stages supports repeatable performance from development through to full-scale production.

- Biomass and other bio derived ingredients
Frequently Asked Questions
How do you prevent contamination in fermentation?
Contamination is minimized by filtering air, water, steam, and feed streams. Emflon® air filters, Profile® Star pre filters, PSS® Plus steam elements and Fuente II sterile liquid filters all contribute to upstream protection.
Why is fermentation broth clarification important?
Clarification prepares fermentation broth for downstream processing by removing cells and solids. This supports consistent operation in subsequent processing steps and helps maintain overall process performance.
What final filtration is used before packaging?
Final microbial reduction is achieved with SUPRAdisc™ II, Fuente II and Supor® Beverage filters, supporting product consistency before packaging.
