Producción de basidiomas de Schizophyllum commune (Fungi: Basidiomycota) en subproductos agrícolas de Tabasco, México

Objective: the in vitro mycelial growth rate of Schizophyllum commune Fr. 1815 strains from Tabasco, Mexico and the production of basidiomas in different regional agricultural substrates was evaluated. Design/methodology/approach: four strains were used: CCG003, CGG009, CCG010 and CGG13, and four substrates: cocoa peel (CP), banana leaves (BL), corn leaves (CL) and as a control, mulatto wood (MW). Based on the speed of growth, two strains and three substrates were selected to evaluate the basidiomas production in two types of containers: plastic bags and rectangular trays. Productivity was assessed based on Biological Efficiency (BE), Yield (Y) and Production Rate (PR). Results: at 12 days of incubation, the highest mycelial growth rate was recorded in CP by CCG003 and CCG013 strains (51.622.1, and 64.418.1 mm d1) and in HM and HP by CCG009 and CCG010 strains (86.917.8, and 587.8 mm d1), compared to the control substrate (from 117.27.4 to 1200.0 mm d1). High production was recorded in the CC by the CCG009 strain, grown in bags, with BE of 12.82.6%, Y of 4.10.8% and PR of 0.70.1%. The production of S. commune was better in the bag than in the tray.Limitations on study/implications: the low moisture retention of the substrate as well as the phenetic plasticity of the species significantly impact the production of basidiomas by inducing connate morphologies of a smaller size.Findings/conclusions: this study represents an advance in the production of basidiomas of this important fungus, as a food alternative for the tropical regions of Mexico.
