BIOCONVERSION AS A METHOD OF UTILIZATION OF POST-EXTRACTION RESIDUES OF FIR TREE GREENS (ABIES SIBIRICA) WITH OBTAINING A FEED ADDITIVE

This article deals with the problem of utilization solid residue fir tree greens formed during industrial production essential oils. The objective this study was to chemical composition bioconversion products substrates based on greens. strain PP-3.2. Pleurotus pulmonarius (Fr.) Quél acted as a biodestructor.
 In process bioconversion, content polysaccharides and lignin substances decreases 38 28%, respectively. Up 20% protein accumulates in amount nucleic acids is no more than 1.5 g per 1 kg, heavy metals does not exceed maximum permissible concentration. decrease mass substrate reaches 15%. When fallen leaves post-extraction poplar buds are added substrate, increases by 3%, substrate-destroying activity fungi also increases. digestibility result 1.6-2.8 times, depending substrate.
 obtained data allow us recommend post-fermented balsamic biomass for use feed additive.
