This work assessed the mycelial growth rate (Kr) and basidiome production of two commercial strains of shiitake mushroomLentinula edodes(B05 and M3790) in formulations composed of lignocellulosic residues from agricultural and agroindustrial activities in Northern Andean Patagonia and woody materials from invasive plants. The formulations consisted of a base substrate, such as willow wood chips (ChS), rosehip wood chips (ChRM), rosehip fluff (PRM) or southern beech shavings (VL), mixed with a supplement, such as wheat bran (ST) or malting barley bagasse (BC). Both strains showed the highest Kr with ChRM-ST. Basidiome production took place over 1 to 4 flushes for a maximum of 124 days. The highest biological efficiencies (EB) were obtained with strain M3790, particularly using ChS (118.86%) and VL (88.73%), both supplemented with ST. Strain B05 showed the highest EB in ChS-ST (54.72%) and in ChRM-BC (50.43%). The results obtained, especially in ChRM and ChS, in addition to their abundance in Argentinian Patagonia, suggest that these materials can be used as substrates for the commercial production of shiitake, an activity that is still not developed on a large scale in this region.

Palabras clave : Agricultural-forestry waste; beer spent grain; edible mushrooms; shiitake; southern beech shavings; wood chips.
