Next generation industrial biotechnology based on extremophilic bacteria

Area of Science:

• Industrial Biotechnology
• Bioprocessing Engineering

Background:

• Traditional industrial biotechnology relies on sterile conditions, expensive equipment (stainless steel bioreactors), and complex separation processes.
• These factors increase production costs and limit the competitiveness of bio-based products, especially amid low petroleum prices.

Purpose of the Study:

• To introduce and describe Next Generation Industrial Biotechnology (NGIB) as a simplified, cost-effective alternative to traditional bioprocessing.
• To highlight the advantages of NGIB, including unsterile operation, reduced energy and water consumption, and simplified procedures.

Main Methods:

• Utilizing microorganisms resistant to contamination, such as halophilic bacteria, in open (unsterile) bioprocessing systems.
• Employing alternative bioreactor materials like ceramic, cement, or plastic for continuous bioprocessing.

Main Results:

• NGIB enables bioprocessing under unsterile conditions, significantly reducing operational complexity and the need for highly trained personnel.
• The technology offers potential for energy, water, and substrate savings, with lower capital investment requirements.

Conclusions:

• NGIB represents a paradigm shift towards more accessible and economical bio-product manufacturing.
• Engineered microorganisms thriving in high salt and alkaline conditions are key to the success of simplified, open industrial bioprocessing.
