SALES-CAMPOS, Ceci  and  ANDRADE, Meire Cristina Nogueira de. Use of wood residues for the cultivation of edible mushroom Lentinus strigosus in the Amazon. Acta Amaz. [online]. 2011, vol.41, n.1, pp.1-8. ISSN 0044-5967.

The objective of this work was to use wood residues from the state of Amazonas for the cultivation of Lentinus strigosus. found in that region. The strain came from the collection of the National Institute of Amazonian Research. Sawdust species Simarouba amara, Ochroma piramidale and Anacardium giganteum were separately used in the preparation of the substrates, supplemented with rice and wheat bran and CaCO3 (80:10:8:2), respectively, with humidity adjusted to approximately 75%. Substrates (500 g) were packed using bags polypropylene, sterilized at 121 ºC for 30 minutes, inoculated and incubated in an acclimatized chamber at 25 ± 3 ºC and relative air humidity of 85% until primordia emission, with temperature reduced from 25 to 23 ± 1 ºC and air relative humidity increased to 85-90% in the fruiting period. Micelial growth occurred within 12 to 20 days and primordia appeared within 15 to 25 days after the inoculation. Harvest occurred three to five days after primordia emission. Biological efficiency (BE, %), yield (g kg-1) and loss of organic matter (PMO, %) were evaluated. Supplemented sawdust were efficient in the cultivation of L. strigosus, presenting BE of 38, 48 and 59%, yield of 98, 119 and 177 g kg-1 and PMO of 42, 59 and 48% for Simarouba amara, Ochroma piramidale and Anacardium giganteum, respectively. The results show the potential use of those residues in the Amazon, as well as the possibility of using the wild strain, to contribute to the improvement of the social and economical conditions of the regional population and sustainability of the biodiversity resources.
