Mars shelter problem can be solved with engineered yeast, gelatin and sand: paper
Future settlers on Mars would need houses, but they must either spend huge sums transporting construction materials from Earth or use enormous amounts of energy to melt Martian soil into bricks. Scientists in Hong Kong say they have developed a quick and low-cost “living” building material made from genetically engineered yeast, gelatin and sand that can be 3D printed under conditions simulating the Martian environment. Their study, published on…
The material was developed by a team of scientists from the Hong Kong University of Science and Technology and the Hong Kong Polytechnic University, led by Professor Qiu Jisheng.
Researchers from Hong Kong presented a biological binder of modified yeast, gelatin and sand that could be printed in 3D under simulated conditions of Mars. The optimized mixture reached about 12 MPa of compressive resistance, 170% more than the control formulation.
A research team from the Hong Kong University of Science and Technology (HKUST) and the Hong Kong Polytechnic University has developed a low-energy 3D printing material that combines genetically modified yeast, gelatin, and Martian soil. This material freezes and hardens in the extreme Martian environment, exhibiting compressive strength comparable to that of low-grade concrete. The research results were published on September 10 in the interna…
