Vizzini (strain 2230 IVK) on three variants of substrate composition. Laboratory, laboratory-production methods for evaluating the effectiveness of growing technology, chemical composition of the obtained raw materials, statistical methods of analysis were applied.</p><p><strong>Results.</strong> The structure and composition of substrates affect the technological characteristics of the culture, physical and chemical properties of fruiting bodies. The shortest fruiting cycle of 35.2 ± 1.7 days was determined for <em>C. aegerita</em> under growing conditions on SC1 substrate which formula included «straw, husks, pellet, rapeseed, corn, and CaCO<sub>3</sub>» in the ratio of 30: 40: 70: 20: 20: 1. The highest yield (170.5 ± 15.2 g per 1 kg of substrate) in the experiment was determined for <em>P. citrinopileatus</em> on the SC1 substrate composed of «straw / pellets  / rapeseed / corn / CaCO<sub>3</sub>» in the ratio 40: 90: 20: 25: 1. Fruiting bodies of <em>P. citrinopileatus</em> obtained from the SC3 substrate composed of  «pellets / rapeseed / corn / CaCO<sub>3</sub>» in the ratio 60: 110: 20: 30: 1 had the highest protein content – 22.47 ± 0.19%, and fruiting bodies from the SC1 substrate had the least amount of proteins – 17.38 ± 2.60%. Fruiting bodies of <em>C. aegerita</em> contained more lipids than those of <em>P. citrinopileatus</em>, but the factor of the influence of the substrate composition on the total amount of lipids for some cultivars was insignificant. The largest amount of endopolysaccharides was isolated from the fruiting bodies of <em>C. aegerita</em> (6.81 ± 0.41%) cultivated on SC3 substrate, and the smallest in the SC1 variant (1.38 ± 0.25%). The content of endopolysaccharides in the fruiting bodies of <em>P. citrinopileatus</em> had less variability from 2.54 ± 0.54 (SC3) to 4.72 ± 0.61% (SC1).</p><p><strong>Conclusion</strong>. Substrate compositions significantly affect the biological efficiency of cultivars and the content of nutrients in fruiting bodies of the studied species. The obtained results enable producers of mushrooms to predict the production efficiency and quality of grown mushrooms in accordance with the use of available raw materials.</p> ER -
