Abstract

Growth and production of the Ling zhi mushroom, Ganoderma lucidum on several agricultural organic wastes such as oil palm mesocarp fiber (MF), rubber wood chips (RWC), mix wood sawdust (MWS) and shredded newspaper (SN), in the laboratory were evaluated. The MF substrate gave the fastest spawn run (15 days), shortest time to primordia formation (26 days), best fructification and highest biological efficiency (5.58%) when compared to all the other substrates. Addition of nutrient supplementations such as paddy bran (PB) and urea (U) further enhanced the growth and production on all substrates. The best combination was MF + 10% PB + 0.01 % U. Evaluation of grains such as barley, wheat, soybean, paddy seeds and mungbean for spawn production were also done. Barley produced the fastest mycelia growth while wheat was found to be the most suitable grain substrate for spawn production. Chemical analysis of the fruiting bodies indicated the presence of quantities of Ca (113.52 -385.43 µg/g), Mg (1142.94 - 2120.28 µg/g), Mn(12.64 - 21.65 µg/g) and Zn (62.86 -122.55 µg/g), and negligible or trace quantities of heavy metals such as Pb (< 4.34 µgig), Cd (< 2.19 µg/g) and Cu (< 3.52 µg/g). Problem encountered during the cultivation of G. lucidum include infestation by common pests such as phorid flies and mites, and the green mold disease cause by Trichoderma sp.
