Summary
Resource conservation is vital for long space missions. Prototype systems for biological wastewater reclamation and cellulose-to-mushroom conversion show promise for reducing resupply needs, offering recycled water and food.
Area of Science:
- Space exploration
- Bioregenerative life support systems
- Resource management
Background:
- Prolonged space missions necessitate significant resource conservation.
- Extensive resupply missions present substantial technological and logistical challenges.
Purpose of the Study:
- To evaluate prototype systems for resource conservation in space.
- To address the need for minimal resupply in long-duration spaceflight.
Main Methods:
- Testing of a biological waste water reclamation system (BWWR).
- Assessment of a waste cellulose to edible mushroom conversion system (CMCS).
- Utilizing crude devices based on original conceptual designs.
Main Results:

Microbial fuel cells (MFCs) are bioelectrochemical devices that generate electricity by exploiting the metabolic processes of electrogenic bacteria. These systems provide a renewable energy source and serve as an innovative method for treating organic waste, such as wastewater.A typical MFC consists of two chambers: an anoxic (oxygen-free) compartment that houses the bacteria and an oxic (oxygen-rich) compartment that contains oxygen as the terminal electron acceptor. Many MFCs use proton...

Microbial fermentation is central to food biotechnology, enhancing flavor, texture, preservation, and stability. Fermentative microorganisms metabolize carbohydrates into organic acids, alcohols, and other metabolites that inhibit spoilage organisms and improve digestibility while contributing distinctive sensory qualities.In baking, amylases naturally present in flour hydrolyze starch into monosaccharides such as glucose, which Saccharomyces cerevisiae ferments anaerobically. Through...

Alcoholic beverages such as wine, beer, and spirits are the products of microbial fermentation processes that transform simple sugars into ethanol and a wide array of complex flavor compounds. These transformations rely on the metabolic activities of specific yeasts and bacteria, which are selected and controlled to yield the desired beverage characteristics.Wine Fermentation and MaturationWine production begins with the crushing of grapes to release juice and pulp, forming a must that is...

Bioreactors are engineered vessels designed to cultivate microorganisms under controlled conditions for industrial bioprocessing. They maintain sterility and allow precise regulation of pH, temperature, oxygen, and nutrient levels to optimize microbial growth and metabolite production. Bioreactors range from small laboratory units of 1 liter to industrial systems holding up to 500,000 liters, though only about 75% of their volume is actively used for fermentation. The remaining headspace...
