Harnessing bioengineered microbes as a versatile platform for space nutrition.

Area of Science:

• Synthetic biology
• Astrobiology
• Food science

Background:

• Long-duration space voyages necessitate sustainable and resilient food production systems.
• Current food manufacturing methods are resource-intensive and generate significant waste.
• Maintaining nutritional and sensory quality in confined environments is a major challenge.

Purpose of the Study:

• To explore the potential of bioengineered microorganisms as a flexible food production platform.
• To consolidate nutritional and sensory attributes into a single microbial system.
• To develop a food system with minimal inputs, footprint, and waste for space exploration and Earth-based applications.

Main Methods:

• Engineering a yeast collection for one-carbon metabolism.
• Optimizing yeast for nutritional content, texture, taste, aroma, and color.
• Evaluating the yeast platform's potential for customizable food production.

Main Results:

• A bioengineered yeast collection can be developed to possess diverse sensory and nutritional characteristics.
• This platform offers a method for producing tailored food components.
• The system demonstrates potential for reduced resource consumption and waste generation.

Conclusions:

• Bioengineered yeast presents a viable solution for sustainable food production in space.
• This microbial food production paradigm can enhance self-sufficiency and reduce environmental impact on Earth.
• Further development could revolutionize food manufacturing for both extraterrestrial and terrestrial applications.
