Cultivation of mushroom Shiitake in coconut wastes supplemented with bran or/and rice bran

Abstract

The objective of this study was to evaluate the use of coconut-husk sawdust supplemented with wheat and/or rice bran as an alternative substrate for axenic production of edible mushrooms. The growth and precocity in relation to the primordial induction and harvest initiation periods of strains of Lentinula edodes were observed, as well as the biological efficiency in the substrate. The growth rate, vigor, period of primordia formation, harvest initiation period and biological efficiency of three Lentinula edodes (LE 01/04, LE 97/38, LE 99/41) strains were evaluated in response to the supplementation of the coconut-husk sawdust based substrate with 0, 5, 20, 30 and 40% of wheat and/or rice bran. The growth and vigor of these Shiitake strains increase with supplementation in all strains tested. There is no primordial formation and production after 18 months of colonization with supplementation.
