Scientists are exploring how yeast could help produce construction materials for future Mars settlements, offering an alternative to transporting heavy machinery and resources from Earth. The approach would use biological processes to convert available materials into usable building components on-site.
Scientists at The Hong Kong University of Science and Technology, led by Jishen Qiu, developed a method to convert Martian sand into a low-grade concrete by mixing it with pig-derived gelatin, engineered yeast coated in mussel-like proteins, and water. Mars' cold, low-pressure atmosphere naturally freeze-dries the mixture, causing water to sublimate and leaving behind a porous, foam-like solid strong enough for construction.
Scientists at Southern Illinois University Carbondale used CRISPR-edited yeast strains to break down PET plastic and plant waste into edible proteins, fats, and flavor compounds, which were then 3D printed into small cookie-shaped snacks called 'ÂBites.' The plastic is first broken down using heat, water, and oxygen before the yeast converts it into a food-like slurry, though the team has not yet tasted the cookies pending university approval.
Scientists at Southern Illinois University Carbondale used CRISPR-modified yeast to convert PET plastic and agricultural waste into proteins, fats, and flavor compounds, which were then 3D-printed into cookie shapes called 'µBites.' The team presented the work at the American Chemical Society meeting in Chicago, though the cookies haven't been tasted yet pending university approval.
