Investigation of the simulated microgravity impact on heavy metal biosorption by Saccharomyces cerevisiae

mycolabadmin

This research shows that yeast commonly used in bread and beer production can absorb dangerous heavy metals from water, and this ability is even stronger in simulated weightlessness conditions. The metal-yeast complexes remain stable as they pass through the digestive system, making them safe for astronauts and potentially useful for cleaning contaminated drinking water in the food and beverage industry.

Iron-Modified Alkaline Lignin Chitosan Aerogel Microspheres for Sb(III) Removal in Water

mycolabadmin

Researchers developed a new material made from iron, lignin (a plant-derived substance), and chitosan that can effectively remove poisonous antimony from contaminated water. When tested, this material successfully removed over 95% of antimony from water samples and could be reused multiple times. The material works by creating chemical bonds with antimony molecules, trapping them on its surface. This environmentally friendly solution could help treat industrial wastewater containing multiple types of heavy metals.

Application of Modified Spent Mushroom Compost Biochar (SMCB/Fe) for Nitrate Removal from Aqueous Solution

mycolabadmin

This research developed a new material made from leftover mushroom compost mixed with iron to clean water polluted with nitrate, a common problem in farming areas. The material works by attracting and trapping nitrate particles, and when tested, it successfully removed up to 19.88 mg of nitrate per gram of the material used. The best results occurred at neutral pH levels and after two hours of contact time. This affordable, environmentally friendly solution could help communities improve their water quality without expensive chemical treatments.
