Molecular and nutritional characterization of an edible mushroom from the Western Ghats of Karnataka, India- A new report

摘要

A delicious edible mushroom vernacularly known as Heggalanabe was collected from the Theertha halli forest area of Western ghats of Shimoga district of Karnataka during first week of August and identified using internal transcribed spacer (ITS) regionof ribosomal DNA sequences. BLAST matches showed 98% indentify with 0.0 evalue with Termitomyces sp. The mushroom mycelia could grow on potato dextrose agar at room temperature under laboratory conditions. The fruit body contained 27.03% crude protein,which is higher than commonly cultivated mushrooms viz., Agaricus bisporus (24.85%) and Pleurotus florida (24.81%) and lesser than the Soybean, a highest protein containing oil seed cum pulse crop. Zinc content was also significantly higher in Termitomyces sp. compared to Pleurotus florida and Agaricus bisporus. Amongst mushrooms, Agaricus bisporus showed significantly higher iron content.
