Potential of utilizing aged bark-and-wood waste through mycological degradation as a biotechnological process

Year: 2024

Type: article

Abstract: Our composition analysis of bark-and-wood waste from a warehouse in the Syktyvkar city revealed a high nutrient content, no toxicity, and the potential for using xylotrophic basidiomycetes for solid state fermentation. Three strains of xylotrophic basidiomycetes (Trametes hirsuta, Fomitopsis pinicola, and Laetiporus sulphureus) were evaluated for their growth rate, growth index, yield of hardly hydrolysable polysaccharides, and cellulase yield when cultivated on the bark-wood waste. The results showed that T. hirsuta exhibited the highest growth rate (4.95– 6.2 mm/day), growth factor (60–77), and the maximum yield of hardly hydrolysable polysaccharides (30.7%) in 30 days. Furthermore, the maximum cellulase yield was 1330 unit/g.
