Studies on the Ganoderma Species of Bangladesh

摘要

Mushrooms have brought revolutions in mycology and hence mushroom science has recently been created to encompass, for convenience, members in the class of Ascomycetes and Basidiomycetes used from ancient times as food materials or food products. Out of 280 described species reported to be present in different countries of the world, Ganoderma lucidum appears as the pivotal species due to its manifold pharmacological attributes as well as artistic values. The samples collected from Bangladesh were pure cultured on potato dextrose agar (PDA). After growth for one week on PDA, mycelium was transferred aseptically to previously sterilized spawning material composed of sawdust (60%), wheat bran (40%) and calcium carbonate (2-4%) distributed in polybags weighing about one kilogram, and the bags were incubated at room temperature. The neck of the spawning packets were punctured and watered weekly. Fruiting bodies appeared on average after three weeks following inoculation and were harvested after one week. Fruiting bodies, 3-4 per packet, weighed 2.68gms on average and were red in colour. The records indicate that this is the first report of the occurrence of G. lucidum (red mushroom) in Bangladesh. Further studies are being planned for devising profitable production technology for G. lucidum.
