Identification of matB used as an endogenous reference gene for the qualitative and real-time quantitative polymerase chain reaction detection of Lentinus edodes

mycolabadmin

This study identifies the matB gene as a reliable genetic marker for detecting shiitake mushrooms (Lentinus edodes) in food products. Researchers developed a simple DNA test that can identify L. edodes in processed foods where it might be fraudulently substituted for more expensive wild mushrooms. The test is highly sensitive, detecting DNA at extremely low concentrations, and works on both raw mushrooms and processed products. This method provides food manufacturers and regulators with an effective tool to prevent mushroom fraud and ensure food authenticity.

Content and Bioaccumulation of Nine Mineral Elements in Ten Mushroom Species of the Genus Boletus

mycolabadmin

This research analyzed the mineral content of ten different species of wild Boletus mushrooms from China to understand their nutritional value and ability to accumulate minerals from soil. The study reveals these mushrooms are excellent sources of essential minerals needed in human diet. Impacts on everyday life: • Identifies wild Boletus mushrooms as good dietary sources of essential minerals like phosphorus, potassium, magnesium, and zinc • Helps consumers understand which parts of mushrooms (caps vs stems) contain higher concentrations of specific nutrients • Provides scientific basis for traditional use of wild mushrooms as nutritious food • Supports food safety by showing these mushrooms’ natural mineral accumulation patterns • Helps foragers and consumers make informed decisions about wild mushroom consumption

Radioactive Artificial 137Cs and Natural 40K Activity in 21 Edible Mushrooms of the Genus Boletus Species from SW China

mycolabadmin

This research examined radioactive contamination levels in edible mushrooms from Southwest China. The study found very low levels of radioactive cesium-137 from nuclear fallout and natural potassium-40 in these mushrooms, indicating they are safe for consumption. Impact on everyday life: – Confirms the safety of wild mushrooms collected in SW China regarding radioactive contamination – Demonstrates the limited impact of global nuclear events on this region’s food supply – Provides baseline data for future monitoring of environmental radioactivity – Supports the continued traditional practice of mushroom foraging in these regions – Helps inform public health guidelines regarding wild mushroom consumption
