Pb immobilization by phosphate-solubilizing fungi and fluorapatite under different Mn2+ concentrations

mycolabadmin

Researchers studied how two types of beneficial fungi (Aspergillus niger and Penicillium chrysogenum) can remove dangerous lead contamination from environments. By adding the mineral fluorapatite and controlling the level of manganese in the growth medium, they found that Aspergillus niger was much more effective at capturing and permanently locking up lead particles, preventing them from leaching back into the environment. The optimal amount of manganese (7.5 mg/L) significantly boosted the fungi’s production of organic acids that capture lead, making this an environmentally friendly solution for cleaning polluted sites.

Alternative oxidase gene induced by nitric oxide is involved in the regulation of ROS and enhances the resistance of Pleurotus ostreatus to heat stress

mycolabadmin

Oyster mushrooms are commonly grown in controlled facilities but struggle with high summer temperatures. This study found that a molecule called nitric oxide helps mushroom cells survive heat stress by activating a special protein called alternative oxidase (AOX), which reduces harmful molecules called reactive oxygen species. By understanding this mechanism, growers may be able to improve mushroom cultivation and yield during hot weather.

Bioaccumulation and physiological changes in the fruiting body of Agaricus bisporus (Large) sing in response to cadmium

mycolabadmin

This research shows that button mushrooms (Agaricus bisporus) can absorb and accumulate harmful cadmium from contaminated soil. When exposed to cadmium stress, the mushrooms increase their protective chemical defenses, including antioxidant enzymes and organic acids, to survive the toxic conditions. The study demonstrates that these edible mushrooms could potentially be used as a practical and cost-effective method to clean up cadmium-polluted soils.

Growth Phase-Dependent Changes in the Carbohydrate Metabolism of Penicillium Strains from Diverse Temperature Classes in Response to Cold Stress

mycolabadmin

This study examined how different fungal strains from cold and warm environments respond to sudden temperature drops. Researchers tracked enzyme activity related to energy production and found that fungi adapted to cold environments handle stress better than warmth-loving fungi. The type of enzyme activity and how old the fungal cells were both affected the response to cold, providing insights that could help predict how disease-causing fungi behave in cold conditions.
