Abstract

The effects of leachate from a methanogenic process concerning acidogenic performance in a cascade process utilizing a rotational drum fermentation system (RDFS) were evaluated. Using fresh soybean meal as substrates, two process configurations represented as Cascade processes 1 and 2 were employed to perform the experimental estimation. Higher apparent first-order hydrolysis rate constants for Cascade processes 1 and 2 were obtained following the addition of leachate, however occupying ratios of acetic acid decreased whereas propionic acid and butyric acid ratios increased in both acidogenic processes.
