Occurrence and Distribution of Antibiotics and Antibiotic Resistance Genes in the Water and Sediments of Reservoir-Based Drinking Water Sources in Henan, China

mycolabadmin

This study examined three drinking water reservoirs in China to understand how antibiotic-resistant bacteria spread through water and sediment. Researchers found that mobile genetic elements (like integrons) play a bigger role than antibiotics themselves in spreading resistance genes among bacteria. One reservoir, Jian’gang, naturally removed most resistance genes as water flowed through, suggesting its natural purification processes are quite effective. Understanding how these factors work together helps protect drinking water supplies from antibiotic-resistant bacteria.

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.

Heavy Metal Remediation by Dry Mycelium Membranes: Approaches to Sustainable Lead Remediation in Water

mycolabadmin

This research shows that dried mushroom root networks (mycelium) can effectively remove toxic lead from contaminated water, making it a natural and sustainable alternative to expensive chemical treatments. When enhanced with phosphate treatment, mycelium can remove over 95% of lead even at high concentrations. The mycelium membranes work well in continuous water filtration systems while being biodegradable and environmentally friendly, offering promising solutions for households and communities dealing with lead-contaminated drinking water.
