SINOPSIS

In this research the effect of sawdust, malt extract, and wheat bran on yield, biological efficiency (BE), and mycelia growth of Ganoderma lucidum was investigated. Three kinds of sawdust (beech, poplar, and hornbeam) as basal medium were mixed with two levels of wheat bran (5% and 10% w/w) and malt extract (2.5% and 5% w/w) as medium supplement for production of G. lucidum in factorial experiments on the basis of completely randomized design with three replications. The results showed that various kinds of sawdust affect fruiting body yield, BE, and mycelia growth rate significantly. The highest fruiting body yield and BE (102.58 g/kg and 12.89%, respectively) were found using hornbeam sawdust. The beech sawdust promotes the mycelia growth rate more than other sawdust. Analysis of variance showed that there is a significant interaction between the sawdust type and wheat bran, sawdust type and malt extract, and wheat bran and malt extract as far as yield and BE of G. lucidum was concerned. A final comparison of the different formulae indicated that the best combinations for high yield (142.44 g/kg) and BE (18.68%) were obtained in a combination of poplar sawdust with 5% malt extract and 10% wheat bran. The highest mycelia growth rate (10.6 mm/day) was obtained in a combination of beech sawdust with 2.5% malt extract and 10% wheat bran.
