Abstract [en]

The effect of mixt. interactions, i.e., synergy and antagonism, previously obsd. in batch operation mode were evaluated under semi-continuous co-digestion of slaughterhouse waste (SB) and its different combinations with manure (M), various crops (VC), and municipal solid waste (MSW). The effects on the process performance and the microbial community structure were studied. The digestion of SB failed at an OLR of 0.9 g VS/L-day. However, stable performance with higher loadings was obsd. for mixts. that displayed synergy obtained earlier in the batch mode (i.e., SB + M, SB + VC + MSW). Bacterial and Archaeal groups increased for the SB + M and SB + VC + MSW, compared with the digestion of SB alone and that for SB + VC. The combination that showed antagonistic effects (SB + VC) resulted in unstable operation and poor representation of methanogens. It was proved that synergetic or antagonistic effects obsd. in batch mode due to the different mixt. compns. could be correlated to process performance, as well as the development of the microbial community structure during semi-continuous operation.
