Abstract

Growing mushrooms on nutrient substrates made of sawdust may be promising avenues for utilization of sawmill waste. The authors have used sawdust of deciduous trees as the basis for a nutrient substrate in growing shiitake mushrooms (Lentinula edodes (Berk.) Pegler) in laboratory conditions. Spent mushroom substrates (SMS) after picking mushrooms can be used as an organic fertilizer and (or) mulch. Applying SMS in growing dill (Anethum graveolens L.) ‘Bushy’ allowed to shorten the seed germination period from 15 to 5 days and obtain a larger amount of green mass. The influence of SMS on the composition and antiradical properties of dill extract has been studied. Essential oil was obtained by water-and-steam distillation; the oil composition was studied by chromatography-mass spectrometry. In control, the main components of the essential oil of dill were α-fellandren – 15.2 %, limonene – 24.2 % and carvon – 42.5 %. When using SMS, the composition of dill essential oil was the same, however, the ratio of the components changed: the content of α-fellandren and limonene increased to 20.5 % and 31.5 %, respectively, while the content of carvon decreased to 31.0 %. Aqueous extracts of dill were studied for antiradical properties for the first time. Antiradical activity was determined in a model reaction with a free stable 2,2-diphenyl‑1-picrylhydrazyl radical and made 27.4 % and 35.3 % in the control and dill grown with SMS, respectively
