The effectiveness of forest resources depends on the comprehensiveness and rationality of their consumption and processing into finished products. This article discusses the problem of using solid fir wood greenery residues generated during the industrial production of essential oils. Bioconversion is considered to be the most promising use. The objective of this research was to study the chemical composition of bioconversion products of fir wood greenery-based substrates. The РР-3.2 strain of Pleurotus pulmonarius (Fr.) Quél was used as a biodestructor. In the process of bioconversion, the contents of polysaccharides and lignin substances is reduced to 38% and 28%, respectively. Up to 20% of protein accumulates in bioconversion products of fir wood greenery. The amount of nucleic acids is not more than 1.5 g per kg; the contents of heavy metals, such as mercury, cadmium, arsenic, and lead, do not exceed the maximum permissible concentration standards. The substrate weight loss reaches 15%. When fallen leaves and post-extraction poplar bud residues are added to the substrate, the substrate-destroying activity of fungi increases, and the protein content increases by 3%. The digestibility of products as a result of bioconversion increases 1.6–2.8 times depending on the substrate composition. The obtained data support the recommendation of post-fermented substrates based on fir wood greenery and balsam poplar biomass for use as a protein feed additive.

通过生物转化方法将提取后的杉木木材绿化残留物与饲料添加剂一起使用

森林资源的有效性取决于其消费和加工成成品的全面性和合理性。本文讨论了在工业生产香精油过程中使用的固态杉木绿色植物残留物的问题。生物转化被认为是最有前途的用途。这项研究的目的是研究杉木绿色基础基材的生物转化产物的化学组成。的РР-3.2应变侧耳肺形（前）Quél被用作生物破坏剂。在生物转化过程中，多糖和木质素物质的含量分别降低到38％和28％。杉木绿色植物的生物转化产品中积累了多达20％的蛋白质。核酸的数量不超过每千克1.5克；重金属（例如汞，镉，砷和铅）的含量不超过最大允许浓度标准。基材重量损失达到15％。将落叶和提取后的白杨芽残留物添加到基质中时，真菌的破坏基质的活性增加，蛋白质含量增加3％。生物转化产物的消化率提高了1.6-2.8倍，具体取决于底物的组成。
