Genetic Characterisation of the Bacterial Microbiota Associating With a Strain of Epichloë Fungal Endophyte of Perennial Ryegrass and the Interaction With Its Paenibacillus Members

mycolabadmin

Researchers discovered that fungal endophytes living inside perennial ryegrass plants host communities of bacteria, primarily from the Paenibacillus genus. Two specific bacterial strains were isolated and found to interact antagonistically, with one strain acting as a ‘keystone’ species that controls the composition of the entire bacterial community. Despite these complex bacterial interactions, the bacteria did not negatively affect the fungal endophyte’s growth, suggesting a balanced symbiotic relationship beneficial to the grass plant.

Ascosphaera apis as a target for the antifungal activity of symbiotic Bifidobacteria in honey bees

mycolabadmin

Researchers found that certain beneficial bacteria (Bifidobacterium asteroides) living in honey bee guts can fight the fungus that causes chalkbrood disease, a serious condition affecting bee colonies. These bacteria produce natural compounds, especially propanoic acid and ethanol, that kill the fungus and prevent it from growing. This discovery offers a safe, natural alternative to chemical treatments for protecting honeybees from fungal infections while maintaining colony health.

Edible Mushrooms and Beta-Glucans: Impact on Human Health

mycolabadmin

Mushrooms contain compounds called β-glucans that can help boost your immune system and reduce inflammation. These compounds show promise in cancer treatment when combined with conventional therapies and may help fight infections. While mushrooms have long been used in traditional medicine, modern research is confirming their health benefits and understanding how they work in the body.

Modulating effects of Phellinus linteus polysaccharides on antioxidant capacity, immune function, intestinal function and microbiota in lipopolysaccharide-challenged broilers

mycolabadmin

Researchers studied how a medicinal mushroom extract called Phellinus linteus polysaccharides could help broiler chickens recover from immune stress caused by bacterial toxins. The supplement improved the chickens’ growth, reduced harmful inflammatory responses, and promoted beneficial gut bacteria while reducing harmful ones. The treatment strengthened the intestinal barrier and restored the chickens’ natural antioxidant defenses. This suggests the mushroom supplement could be a natural alternative to antibiotics for improving poultry health on farms.

The progress of the microbe-gut-brain axis in sepsis-associated encephalopathy

mycolabadmin

Sepsis can cause brain dysfunction called sepsis-associated encephalopathy, leading to memory problems and confusion in about one-third to two-thirds of sepsis patients. The bacteria in your gut communicate with your brain through multiple pathways, and when sepsis disrupts this communication, it causes harmful inflammation in the brain. Treatments like probiotics and transplanting healthy gut bacteria from donors show promise in animal studies and early human trials for improving memory and cognitive function after sepsis.

mGem: Submarine mycology—an analog to astromycology

mycolabadmin

Scientists are studying fungi in submarines to better understand fungal health risks for astronauts in space. Both submarines and spacecraft are enclosed environments where fungi can grow, causing infections and other health problems. The same types of fungi found growing in submarines have been detected on the International Space Station. By learning from decades of submarine research, space agencies can better prepare for and prevent fungal-related health issues during long space missions.

Microbial communities inhabiting the surface and gleba of white (Tuber magnatum) and black (Tuber macrosporum) truffles from Russia

mycolabadmin

This research identifies the various microorganisms living inside truffles, particularly Tuber magnatum (white truffle) and Tuber macrosporum (black truffle). The study found that a yeast-like fungus called Geotrichum consistently lives in both truffle types and likely helps with spore dispersal through smell-producing compounds. The researchers discovered that different parts of the truffle have different microbial communities, which explains why truffles have such unique flavors and aromas.
