On site discrimination between two closely related commercial strains of oyster mushroom using a loop-mediated isothermal amplification (LAMP) test

mycolabadmin

Scientists developed a quick molecular test to identify two specific commercial oyster mushroom strains (SPOPPO and ALLERPO) in less than 30 minutes using a technique called LAMP. These sporeless mushroom strains were created to reduce respiratory health problems that workers develop from inhaling mushroom spores. The new test helps mushroom producers and breeders quickly verify strain identity in the field to prevent unauthorized copying of these valuable varieties and to catch products of suspect origin.

Barcode high-resolution melting (Bar-HRM) analysis to authenticate true cinnamon (Cinnamomum verum) from its adulterants and contaminants

mycolabadmin

This study developed a rapid and cost-effective DNA test to verify that cinnamon products are authentic true cinnamon (Ceylon cinnamon) rather than cheaper substitutes. The test uses DNA barcoding and melting curve analysis to distinguish true cinnamon from three common adulterants and can also detect contamination with a toxic fungus. The method is particularly useful for processed cinnamon products like powder where traditional identification methods don’t work, helping protect consumers and maintain market integrity for authentic Sri Lankan cinnamon.

Morphological, Genetic, and Microbiological Characterization of Tuber magnatum Picco Populations from “Alto Molise”, Central-Southern Italy

mycolabadmin

Italian white truffles from the Molise region were studied to identify unique characteristics that could help verify their authenticity and origin. Researchers examined the physical features, genetic makeup, and microbial communities of truffles from four different municipalities. They discovered that truffles from certain areas share a unique genetic marker not found elsewhere in Italy, and that different populations have distinct microbial communities. These findings could help prevent truffle fraud and protect the reputation of Molise truffles in the global market.
