Screening and Optimization of Solid-State Fermentation for Esteya vermicola, an Entomopathogenic Fungus Against the Major Forest Pest Pine Wood Nematode

mycolabadmin

Scientists optimized how to grow large quantities of a beneficial fungus called Esteya vermicola in solid fermentation, which kills the pine wood nematode pest that destroys pine forests. By testing different combinations of ingredients (wheat bran, corn flour, soybean flour, glucose, yeast extract, and magnesium sulfate) and environmental conditions (temperature, humidity, inoculation volume, and time), researchers increased fungal spore production more than 4-fold. These results provide a practical method for producing biopesticide products to protect pine forests from this damaging pest.

Tackling Conifer Needle Cast and Ash Dieback with Host-Derived Microbial Antagonists Exhibiting Plant Growth-Promoting Traits

Scientists discovered beneficial bacteria living on ash and pine trees that can fight two major forest diseases: ash dieback and needle cast. These bacteria not only kill the harmful fungi but also help trees grow stronger by improving nutrient absorption. This research offers promise for protecting European forests without relying on chemical fungicides, creating a more natural and sustainable approach to forest health.

Effects of Resinous Compounds from Pine Trees on Spore Germination and Mycelial Growth of a Nematophagous Fungus, Esteya vermicola

Researchers tested whether a beneficial fungus called Esteya vermicola could be injected into pine trees to fight pine wilt disease. However, they discovered that natural resinous compounds found in pine trees strongly inhibit the growth of this fungus. The findings suggest that trunk injection of this fungus may not be an effective treatment because the tree’s own defensive compounds prevent the fungus from establishing itself and fighting the harmful nematodes.
