Painting Mars green! Amazing oxygen-producing paint could make space colonization possible


GUILDFORD, United Kingdom — Perhaps there might be a future on Mars in spite of everything. Scientists from the College of Surrey in the UK have developed a groundbreaking eco-friendly paint that not solely captures carbon dioxide (CO2) but additionally produces oxygen — which might probably assist people stay on the Crimson Planet. Named “Inexperienced Residing Paint,” this creation makes use of a bacterium generally known as Chroococcidiopsis cubana, generally present in harsh desert circumstances and famend for its potential to thrive with minimal water.

Biocoatings, the center of this eco-paint, are a singular sort of water-based paint that encapsulates live bacteria inside its layers. These coatings have a large number of purposes, from carbon capture to appearing as bioreactors and biosensors.

“With the rise in greenhouse gases, notably CO2, within the ambiance and issues about water shortages attributable to rising world temperatures, we want revolutionary, environmentally pleasant, and sustainable supplies,” says Dr. Suzie Hingley-Wilson, a senior lecturer in bacteriology on the College of Surrey, in a university release. “Mechanically strong, ready-to-use biocoatings, or ‘dwelling paints,’ might assist meet these challenges by reducing water consumption in sometimes water-intensive bioreactor-based processes.”

To check the potential of Chroococcidiopsis cubana as a biocoating, researchers immobilized these resilient micro organism inside a sturdy biocoating comprised of polymer particles in water. After thorough drying and rehydration, they discovered that the micro organism throughout the biocoating might produce as much as 0.4 grams of oxygen per gram of biomass per day whereas effectively capturing CO2. Steady oxygen measurements indicated that the micro organism maintained their exercise ranges persistently for over a month.

In a hanging distinction, related experiments have been carried out utilizing the bacterium Synechocystis sp., which is usually present in freshwater environments. In contrast to its desert counterpart, this bacterium did not produce oxygen throughout the biocoating.

“The photosynthetic Chroococcidiopsis have a rare potential to outlive in excessive environments, like droughts and after excessive ranges of UV radiation publicity,” says research lead creator Simone Krings, a former postgraduate researcher within the Division of Microbial Sciences on the College of Surrey. “This makes them potential candidates for Mars colonization.”

Joseph Keddie, professor of soppy matter physics on the College of Surrey, expressed gratitude for the analysis grant from the Leverhulme Belief that enabled this interdisciplinary undertaking.

“We envision our biocoatings contributing to a extra sustainable future, aligning completely with the imaginative and prescient of our Institute for Sustainability, the place each Dr Hingley-Wilson and I are fellows,” notes Keddie.

The research is printed within the journal Microbiology Spectrum.
