Fig. 3From: Evaluation of acidogenesis products’ effect on biogas production performed with metagenomics and isotopic approachesBioreactors’ performance (COD utilization and methane production) during Experiments 1 and 2. The data were used in the statistical calculations of statistical significance of differences in medians (MWt) and distributions (KSt) between bioreactors performance during Experiments 1 and 2 (see Additional file 2)Back to article page
