“…Co-digestion of KW with other wastes, like press water from organic municipal wastes, sewage sludge and animal manures has been widely studied (Kim et al, 2004;Nayono et al, 2010;Zhang et al, 2013;Tian et al, 2015;Tasnim et al, 2017). However, limited reports can be found on successful performance of single-stage AD system treating KW (Zhang et al, 2012).…”

“…The main advantage of co-digestion is to bring a synergy between two/three compatible feedstocks in term of overall nutrient supplementation (including TE) with a low cost. The mixing of feedstock has also an impact on the speciation of TE with the blending of inorganic fraction and the potential release of bound TE to more available fraction (Tian et al 2015). In both cases, this work should be considered on a long-term basis to first quantify the beneficial effect of TE supplementation on the AD performance.…”

This study focused on the effect of the variation of intermediate volatile fatty acids (VFAs) caused by the change of organic load on methane production and methanogenic community shift during anaerobic digestion (AD). Eight groups with different F/I (VS food wastes :VS sludge ) were conducted, while the inoculation sludge had a same amount. Operational performance for every groups was monitored by assessing biological activity, methane production, concentration of VFAs. The major intermediate VFAs of anaerobic digestion were acetate, propionate, iso-butyrate, n-butyrate, n-valerate and iso-valerate; and acetate and n-butyrate were the most abundant components. The increasing of F/I changed the predominant VFAs type from acetic acid to n-butyric acid, while the total VFAs concentration increased. Besides, the methane production increased and then decreased, and reached the maximum (170.3 ml/g added VS -1 ) at F/I of 1. The methanogenic diversity was screened using the high-throughput sequencing, which shown VFAs had a significant impact on the archaeal community as the dominant archaea shifted from Methano bacterium to Methano sarcina.
