Isolation of Bacteria from Lead-Contaminated Soil and Bacterial Interaction Test with Plant Growing on Lead-Amended Media

mycolabadmin

Researchers discovered special bacteria from lead-contaminated soil that can accumulate and neutralize lead while also producing a plant hormone called IAA. When these bacteria were added to three ornamental plants growing in lead-contaminated soil, the plants grew better and absorbed less lead. This discovery offers a promising natural and sustainable way to clean up lead-polluted environments by combining bacteria and plants.

Isolating and Identifying One Strain with Lead-Tolerant Fungus and Preliminary Study on Its Capability of Biosorption to Pb2+

mycolabadmin

Scientists discovered a fungal strain called Sarocladium that can effectively absorb lead from contaminated soil and water. This strain works best under specific conditions (25°C temperature and neutral pH) and can remove up to 37.75% of lead ions from highly contaminated solutions. The fungus captures lead through various chemical compounds on its cell surface, showing great promise as an inexpensive and environmentally friendly solution for cleaning up lead-polluted environments.

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.
