Identification of antagonistic activity against Fusarium, and liquid fermentation of biocontrol Bacillus isolated from wolfberry (Lycium barbarum) rhizosphere soil

mycolabadmin

Researchers isolated a beneficial bacterium called Bacillus subtilis from wolfberry soil that fights a fungal disease called Fusarium root rot. Through careful optimization of growing conditions, they increased the bacteria’s effectiveness at killing the harmful fungus by about 15%. When added to wolfberry seedlings, this bacterium not only prevented fungal disease but also boosted plant growth significantly.

Production of fungal hypocrellin photosensitizers: Exploiting bambusicolous fungi and elicitation strategies in mycelium cultures

mycolabadmin

Hypocrellins are powerful compounds from fungi that can treat cancers and infections through light-activated therapy. Since wild sources are limited, scientists are growing these fungi in laboratory cultures and using special techniques to boost production. This review summarizes the best methods for producing hypocrellins, from choosing the right fungal strains to optimizing growing conditions and using natural stimulants to increase yields.

Comparative metabolic profiling of the mycelium and fermentation broth of Penicillium restrictum from Peucedanum praeruptorum rhizosphere

mycolabadmin

Researchers studied a fungus called Penicillium restrictum found in the roots of QianHu, a traditional Chinese medicine plant. Using advanced chemical analysis, they discovered that this fungus produces important medicinal compounds called coumarins, with peak production around day 4 of growth. The fungus appears to produce even more types of these beneficial compounds than the plant itself, suggesting it could be used to manufacture these medicines more efficiently.

Engineered biosynthesis and characterization of disaccharide-pimaricin

mycolabadmin

Scientists engineered a bacterium to produce a modified antibiotic called disaccharide-pimaricin that fights fungal infections with much better safety. This new compound dissolves better in water (107 times more soluble) and is much less toxic to human blood cells (12.6 times safer) compared to regular pimaricin, while still maintaining antifungal effectiveness. Through optimized fermentation processes, they achieved high production yields of 138 mg/L, making this a promising candidate for safer antifungal treatments.

Comparative proteomics reveals the mechanism of cyclosporine production and mycelial growth in Tolypocladium inflatum affected by different carbon sources

mycolabadmin

Researchers studied how different sugars (fructose and sucrose) affect a fungus’s ability to produce cyclosporine A, an important drug used after organ transplants to prevent rejection. Using advanced protein analysis techniques, they found that fructose makes the fungus better at producing the drug, while sucrose makes it grow more mycelium (fungal threads). By identifying the specific proteins involved in each process, scientists can now develop better methods to produce more of this valuable medicine.

Hypoglycemic Effect of Pleurotus citrinopileatus and Hericium erinaceus Buccal Tablets on Diabetic Mice

mycolabadmin

Researchers created special tablets from two edible mushrooms (yellow oyster mushroom and lion’s mane) enriched with trace elements (chromium, zinc, germanium) to treat diabetes in mice. After three weeks of treatment, the high-dose tablets reduced blood sugar levels by 29%, improved cholesterol levels, boosted the body’s natural antioxidant defenses, and shifted the gut bacteria toward beneficial types that support metabolic health. These results suggest that mushroom-based treatments could potentially offer a natural way to help manage diabetes.

Engineered biosynthesis and characterization of disaccharide-pimaricin

mycolabadmin

Scientists successfully created a genetically engineered bacterium that produces a safer version of an antifungal drug called pimaricin. The new version, called disaccharide-pimaricin, dissolves much better in water and causes significantly less damage to human blood cells, making it a much safer option for treating fungal infections. Although it’s slightly less effective at killing fungi, the improvement in safety and solubility makes it a promising candidate for treating eye infections and other fungal diseases.
