Abstract
The objective of the study was to evaluate the production of two strains of Ganoderma lucidum on agricultural waste and carry out bromatological analyses of the basidiomata obtained from the cultivation. The experiment was carried out at the Mushroom Module at the School of Agronomic Sciences of the São Paulo State University (FCA/UNESP - Botucatu, SP, Brazil) and two strains were used (GLM-09/01 and GLM-10/02) which were cultivated on waste, oat straw, bean straw, brachiaria grass straw, Tifton grass straw and eucalyptus sawdust under two situations: with (20%) and without (0%) supplementation with wheat bran. All the waste was taken from dumps of agricultural activities in Botucatu-SP. Both treatments were carried out in 10 repetitions, totaling 200 packages. The mushrooms cultivation took 90 days. Next, the biological efficiency of the treatments and the bromatological analysis of the basidiomata were evaluated. The biological efficiency (BE) values (%) varied from 0.0 to 6.7%. In the mushroom bromatological analyses, the results ranged from 8.7 to 13.7%, from 2.0 to 6.7%, from 0.83 to 1.79% and from 38.8 to 54.5%, for total protein, ethereal extract, ash and crude fiber, respectively. Thus, we conclude that the substrates which presented the greater yield were the brachiaria straw, 20% in both strains tested (GLM-09/01 and GLM-10/02) and the bean straw, 20% in the strain GLM-10/02. The mushrooms showed high levels of ethereal extract, fibers and ashes and a low level of proteins. Key words: Ganoderma lucidum, bromatological analyses, mushroom.

The mushroom consumption is a millennial habit in many cultures
This study aimed to evaluate the production of two strains of G. lucidum on agricultural waste and carry out bromatological analyses of the initial and residual substrates and of the basidiomata obtained in cultivation
The strains of G. lucidum used in the experiment were GLM-09/01 and GLM-10/02, which are preserved in mineral oil at the Mushroom Module Bank matrix,+ Department of Plant Production, Plant Defense - FCA/UNESP, Botucatu
Summary
The mushroom consumption is a millennial habit in many cultures. Such interest is explained by the fact that these macrofungi present several medicinal and nutritional characteristics. These beings were even considered as deities by some civilizations, and were often used in religious ceremonies. Nowadays, they have a guaranteed market in many places around the world, because of their importance in medicine, and because they are obligatory elements in various cuisines, mainly in the Italian and French. Among the mushrooms with a pharmacological value, the Ganoderma lucidum, (known as orelha-de-pau; Reishi by the Japanese and Ling Zhi by the Chinese) raised much interest on such potential, as they are reported mainly by their medicinal power among their numerous properties, and they can be used for preventing and treating various diseases, including cancer and AIDS (Russell and Paterson, 2006)
