Accelerating Bioprocess Optimization with Lab-Scale Parallel Fermenters

Accelerating Bioprocess Optimisation with Lab-Scale Parallel Fermenters

In modern bioprocess development, speed, accuracy, and scalability are everything. Whether working in precision fermentation, probiotics, biofertilizers, biologics, or food-tech, researchers must quickly screen multiple process conditions and identify the optimal combination of media, gas compositions, agitation profiles, and control strategies. This is where lab-scale parallel fermenters have transformed the landscape—enabling scientists to run simultaneous, highly controlled batches under varying parameters to accelerate decision-making and reduce development time.

What Is a Lab-Scale Parallel Fermenter?

A lab-scale parallel fermenter is a multi-vessel fermentation system designed to run multiple experiments side-by-side under fully independent or semi-independent control. Each vessel typically includes:

• Automated control of pH, temperature, DO, level, and foam

• Mass flow controllers (MFCs) for precise Air, O₂, N₂, and CO₂ supply

• Servo motor–based agitation systems for fine control over RPM and torque

• Advanced data acquisition and control software

• Scalable geometries to mimic pilot and production fermenters

These systems are engineered to generate high-quality, reproducible data while drastically reducing the number of runs required to optimise a process.

Why Parallel Fermentation Is a Game-Changer for Bioprocess Optimisation

1. Faster Process Development:

Running experiments sequentially slows down optimisation. Parallel fermenters allow researchers to:

• Execute 4–12 fermentation runs at once.

• Test different parameters simultaneously (pH setpoints, agitation profiles, media compositions, gas ratios).

• Generate statistically strong datasets in a single cycle.

This reduces development timelines from months to weeks.

2. Ideal for Design of Experiments (DOE)

Design of Experiments (DOE) is a structured approach used in industrial bioprocess optimisation to systematically study multiple variables at once. Parallel fermenters make DOE practical and efficient by:

• Allowing each vessel to represent a unique condition

• Enabling multi-factor optimization: temperature, inoculum %, agitation, gas blends, feed rates

• Producing robust, high-throughput datasets

• Reducing trial-and-error cycles

With DOE integrated into a parallel fermenter workflow, teams can quickly identify optimal conditions and develop scalable, repeatable bioprocesses.

3. Precision Fermentation Requires Precision Control

For applications such as alternative proteins, enzymes, therapeutics, and specialty ingredients, maintaining tight control over the microenvironment is essential. Parallel fermenters offer:

• Mass flow controllers (MFCs) for accurate real-time control of Air, O₂, N₂, and CO₂

• Servo-driven agitation for consistent mixing and shear control

• Automated DO, pH, and feeding strategies

• Real-time data logging and advanced analytics

This level of precision ensures reproducibility and helps understand how microbes respond to different dynamic conditions.

4. Improved Scale-up Success

Lab-scale data often fail to translate to pilot and production levels due to poor environmental replication. Parallel systems mirror industrial geometry and equip:

• Similar aspect ratios

• Similar agitation and mass transfer models

• Automated control algorithms

• High-resolution MFC data

This dramatically increases the likelihood that optimised lab-scale conditions will perform well in 100 L, 500 L, or even 1,000 L production fermenters.

5. Reduced Cost & Resource Utilisation

Parallel fermentation minimises:

• Media consumption

• Energy use

• Number of sequential runs

• Man-hours spent on repetitive tasks

With multiple vessels running simultaneously, teams produce more usable data with fewer resources.

Lab-scale parallel fermenters dramatically accelerate bioprocess development by enabling rapid, data-driven optimisation with precise control over gas flow, agitation, and operational parameters. They help scientists achieve faster results, reduce costs, and improve scale-up success across precision fermentation, food-tech, agri-tech, and biopharma applications.
