The influence of the fractional composition of plant raw materials on the process of bioconversion of basidiomycetes

Abstract

The paper presents the results of the influence of the fractional composition of plant waste - fallen poplar leaves (Populus balzamifera L.) on the growth and development of basidiomycetes (Fp5-15 Fomitopsis pinicola and PP-3.2 Pleurotus pulmonarius), as well as on the yield of the final product. The use of renewable resources and leaf litter as a substrate in biotechnological processes has broad economic and environmental implications. Cultivation was carried out using solid-phase fermentation for 12 days. The values of bioconversion process factors were obtained using the STATGRAPHICS® Centurion software package. It has been established that the fractional composition of plant raw materials can have a significant impact on the bioconversion process; the most favorable fraction size is 5-6 mm (PP-3.2 P. pulmonarius) and 7-8 mm (Fp5-15 F. pinicola).
