<P><B>Abstract</B></P> <P>The goal of this study was to determine the kinetic parameters of methane production during anaerobic fermentation of mixtures of chicken manure with sawdust and wheat straw overgrown with fungi. Pre-treatment of wheat straw was carried out with <I>Pleurotus ostreatus</I> and <I>Trametes versicolor</I> white-rot fungi. Mixtures of chicken manure with sawdust and wheat straw overgrown with fungi at different mass ratios (50:50, 60:40 and 80:20) were used as a substrate for anaerobic fermentation. For the control, ordinary wheat straw was used. Anaerobic fermentations were performed at (35, 40 and 45) °C. An individual process of anaerobic fermentation was maintained at constant temperature for 21 days. During the process, the volume and concentration of biogas produced were monitored.</P> <P>The most biogas produced was recorded for the straw overgrown with <I>Pleurotus ostreatus</I> fungi (ratio 50:50) at 45 °C, and the least in the case of straw overgrown with <I>Trametes versicolor</I> fungi (ratio 80:20) at 35 °C. At the beginning of anaerobic fermentation, the methane concentration increased faster at a higher temperature, while after 21 days, it was between 53 and 56% regardless of temperature.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Pre-treatment of wheat straw was carried out with white-rot fungi. </LI> <LI> Anaerobic fermentations of chicken manure and wheat straw were performed. </LI> <LI> The volume and concentration of produced biogas were monitored. </LI> <LI> Kinetic study of anaerobic fermentation was conducted. </LI> </UL> </P> <P><B>Graphical abstract</B></P> <P>[DISPLAY OMISSION]</P>
