The effectiveness of influence of biocomposite of fungi Basidiomycota upon the emission of carbon dioxide from cattle manure

Abstract

Goal. To determine the effectiveness of the influence of biocomposite of fungi Basidiomycota in different dilutions on the emission of carbon dioxide from cattle manure at mesophilic conditions of anaerobic digestion (in vitro). Methods. The study was carried out with the use of chemical, analytical and mathematical-statistical methods. Results. By results of the conducted researches it is established that after entering biocomposite of fungi Basidiomycota in manure substrate of cattle, regardless of the ratio of dilution (1:10 and 1:5), they observed a decrease in anaerobic fermentation during the study period, as evidenced by a decrease in pH on 1.9–2.1 units. It is established that at addition to metane-generating raw materials (cattle manure) of biocomposite of fungi Basidiomycota in dilution of 1:10 the output of carbon dioxide was below the control on 1.48 dm3, and at a dilution of 1:5 — on 1.58 dm3. Consequently, the use of biocomposite of fungi Basidiomycota in mesophilic conditions of anaerobic digestion of cattle manure (in vitro), in a dilution of 1:10 and 1:5 reduces the output of carbon dioxide, respectively, on 93% and 100%. Conclusions. It is experimentally proved and scientifically substantiated the effective impact of biocomposite of fungi Basidiomycota in the emission of carbon dioxide from cattle manure. Based on the results obtained during the research it is found out that the most effective influence on the level of carbon dioxide detects biocomposite of fungi Basidiomycota in a dilution of 1:5, and therefore, it can be used as an effective means to reduce the level of carbon dioxide to maintain clean environment during the fermentation of by-products of animal origin.
