Taxonomical, nutritional and biochemical characterization of Panus lecomtei mushroom from India and its cultivation

Abstract

Panus lecomtei is emerging as an edible mushroom found worldwide and particularly in the Northern Hemisphere. The mushroom contains a substantial amount of useful nutritional and medicinal compounds. In the present study, we have examined a specimen of P. lecomtei submitted to the ICAR−Directorate of Mushroom Research gene bank. The specimen was examined for taxonomical characters using classical and molecular tools. Attempts were made for cultivation of this mushroom under controlled conditions using sawdust-based substrate. The specimen was characterized by its purplish fruiting body having coarse, rigid, dense hairs on the cap, pubescent stipe, and abundant metuloids. Molecular identification through conserved ITS region was done and the sequence was deposited in NCBI GenBank under accession number MN332200. Nutritional profiling and biochemical analysis showed that the mushroom contained high carbohydrate but low fat contents. The mushroom showed the presence of phenolics, β-carotene, and lycopene. The analysis also showed substantial antioxidant properties in the mushroom. The findings presented herein point out that P. lecomtei can be used as a potential edible mushroom for diversification of mushroom production in India.
