A Modular Chain Bioreactor Design for Fungal Productions

Area of Science:

• Biotechnology
• Fermentation Technology
• Bioprocess Engineering

Background:

• Plastic bag bioreactors are common for solid culture fermentation.
• Existing systems often lack effective aeration and modularity.
• Challenges include maintaining individual culture integrity and preventing contamination.

Purpose of the Study:

• To develop an improved plastic bag bioreactor system with enhanced aeration.
• To enable modular connectivity for sensors and environmental control.
• To demonstrate the ability to culture different microorganisms independently within the system.

Main Methods:

• Development of a modular chain bioreactor (MCB) system with specialized connection elements.
• Integration of filtered connections for air and moisture circulation.
• Comparative analysis of biomass production against traditional bag systems.
• Contamination experiments between interconnected bioreactor bags.

Main Results:

• The MCB system provides more effective aeration conditions.
• Independent culturing without cross-contamination between bags was achieved.
• Filters effectively prevented microbial transfer between cultures in different bags.

Conclusions:

• The developed modular chain bioreactor (MCB) system offers a significant advancement over traditional plastic bag bioreactors.
• The system ensures effective aeration, modular control, and prevents inter-bag contamination.
• This innovation supports efficient and safe solid culture fermentation processes.
