Actinorhizal plants and Frankiaceae: The overlooked future of phytoremediation

mycolabadmin

Actinorhizal plants are special trees and shrubs that team up with beneficial bacteria called Frankiaceae to clean up polluted and degraded soils. This natural partnership helps these plants survive harsh conditions like salty or heavy metal-contaminated soil while also cleaning up the environment. The bacteria help the plants by providing essential nitrogen and improving their ability to tolerate pollution, making them an inexpensive and sustainable solution for restoring degraded farmland.

Mechanisms and impacts of Agaricus urinascens fairy rings on plant diversity and microbial communities in a montane Mediterranean grassland

mycolabadmin

Fairy rings created by the mushroom Agaricus urinascens dramatically transform Mediterranean grasslands. These fungal rings create zones of dead plants and altered soil conditions, killing vegetation and reducing plant species diversity by 40% at the fungal front. The fungi coat their mycelium with calcium oxalate crystals and create water-repellent soil conditions that essentially drown plants by preventing water absorption, ultimately favoring fast-growing grasses over diverse wildflower communities.

Effect of AgNPs on PLA-Based Biocomposites with Polysaccharides: Biodegradability, Antibacterial Activity and Features

mycolabadmin

Scientists created new eco-friendly plastic films made from corn-based PLA combined with natural starches and tiny silver particles. These films can break down in soil while also killing harmful bacteria, making them ideal for food packaging. The materials maintained good antibacterial properties even as they slowly degraded in the environment, showing promise as sustainable alternatives to conventional plastics.
