Characteristics of the acidic effluent resulting from molasses fermentation used as the substrate for methanogenesis, and the effluent from the methanogenic process.

1 not-centrifuged effluents contained microbial cells2 the protein concentrations were determined in non-centrifuged (containing microbial cells) samples, while the concentrations of the other components were determined in centrifuged samples.3 the content of Fe(II) in the methane-yielding granular sludge in the UASB bioreactor was 5.2 ± 0.7 mM (n = 3).Characteristics of the acidic effluent resulting from molasses fermentation used as the substrate for methanogenesis, and the effluent from the methanogenic process.
