Selection of alternative substrates for shiitake cultivation in southern Amazonia

Abstract

Lentinula edodes is the second most consumed mushroom in Brazil. It has high protein content
and low fat content. Its cultivation was carried out with eucalyptus logs, however due to
the great availability of wood residues today shiitake can be cultivated in substrates based on
sawdust. However, these substrates present very low levels of nitrogen, being recommended
supplementation, to potentiate Colonization of the fungus on the substrate. The objective of
this work was to verify in vitro the best concentration of rice bran in the compound of agroindustrial
residues based on teak sawdust, rice husk and coffee husk on the mycelial growth of
the edible fungus Lentinula edodes. The experiment was conducted in DIC with 4 treatments,
which consisted in the supplementation of the compound with rice bran in the concentrations
of 0, 5, 10 and 15%. The 15% rice bran favored the mycelial development of edible fungus
Lentinula edodes.
