Cystobacter fuscus HM-E: a novel biocontrol agent against cotton Verticillium wilt

mycolabadmin

A naturally occurring bacterium called Cystobacter fuscus shows great promise as a biological control agent against a serious fungal disease that damages cotton plants. When formulated as a solid product and applied to soil, this microorganism was able to prevent disease in over 70% of cotton plants tested in greenhouse experiments. The bacteria work by attacking and breaking down the fungal pathogen while also promoting healthier plant growth, offering farmers an environmentally friendly alternative to chemical fungicides.

Paraboremia selaginellae enhances Salvia miltiorrhiza growth and cadmium tolerance via modulating root architecture and cadmium speciation in contaminated environments

mycolabadmin

A beneficial fungus called Paraboremia selaginellae was found to help medicinal plants grow better in soil contaminated with cadmium, a toxic heavy metal. When this fungus colonizes plant roots, it reduces how much cadmium the plant absorbs and improves the soil’s nutrient content. This natural approach offers a promising solution for growing medicinal plants safely in polluted soils without expensive chemical treatments.

Elucidation of Mechanism of Soil Degradation Caused by Continuous Cropping of Dictyophora rubrovalvata Using Metagenomic and Metabolomic Technologies

mycolabadmin

When farmers grow Dictyophora rubrovalvata mushrooms in the same soil repeatedly, the soil becomes degraded and mushroom production fails. Scientists found that repeated cultivation changes the soil’s microbe populations, reducing beneficial bacteria while increasing harmful fungi, and toxic compounds accumulate that further damage mushroom growth. By understanding these mechanisms through DNA sequencing and chemical analysis, better strategies can be developed to maintain healthy soil for sustainable mushroom farming.
