“…The relative abundance of archaea as bioaugmentation culture in this study was low compared to several studies using bioaugmentation cultures with higher archaea abundance (Li et al, 2018a;Li et al, 2018b;Jiang et al, 2020). The fundamental difference is due to the enrichment of the bioaugmentation culture.…”

“…The first peak value with bioaugmentation is 717 L/kg VSadded followed by second and third peak value 893.88 L/kgVSadded and 512.74 L/kgVSadded, respectively. This implied that initial microbial consortium was strengthened with bioaugmentation culture (Jiang et al, 2020). Then bioaugmentation shows a positive impact because it can increase the production of the average methane yield from FW is 396 L/Kg VS (Vögeli et al, 2014).…”

“…The increase of Firmicutes was caused by the BS that dominated by Firmicutes. Bioaugmentation using the same microbes as the original microbes that have been adapted in the AD reactor can increase their population (Jiang et al, 2020). The increase of Bacteroidetes in the reactor might suggest a preferable degradation tendency for nitrogenous compounds.…”

“…Therefore, choosing the mixed culture for bioaugmentation might be more advantageous as the introduced microbial consortium could provide a metabolic diversity and robustness to survive in a bioreactor containing an established indigenous community (Li et al, 2020c). As the previous studies reported, bioaugmentation has been successfully increase AD performance using enriched culture from full-scale anaerobic digesters (Li et al, 2018a;Li et al, 2018b;Jiang et al, 2020). However, limited knowledge in previous research about bioaugmentation of pilot-scale for treating FW.…”

The number of microorganisms is the key factor affecting biodegradation capacity for anaerobic digestion (AD). Bioaugmentation strategy using an enriched culture has been known give supplementary microorganisms and consequently improve the AD performance, however bioaugmentation using a microbial consortium without enrichment for treating food waste (FW) is unknown. In the present study investigated whether bioaugmentation can improve the AD performance of FW, as well as the effect of addition microbial consortium on the microbial community. This pilot scale study using stirrer-less reactors made of LLDPE, with the total and effective volume of 462 L and 369 L, respectively. Bioaugmentation seed (BS) was a cow manure microbial consortium collected from slaughterhouse in Curug, Depok and the frequency of bioaugmentation was performed in every three days. The microbial community was examined using metagenomic next-generation sequencing (NGS). The effect of bioaugmentation using BS without enrichment was revealed as well. Findings demonstrated that effectively increase biogas production (201 L/day) and methane yield (546 L/kg VSadded), compared to non-bioaugmentation (66 L/day) and (296 L/kg VSadded). The increased biogas production and methane yield shows the feasibility of applying cow manure (CM) for bioaugmentation in AD of FW. Furthermore, NGS analysis showed that BS enhanced the population of Methanosarcina and Methanosaeta. The abundance at 17.29% and 11.29%, respectively. The higher Methanosarcina and Methanosaeta indicate the acetoclastic pathway was dominant on methanogenesis. The success of bioaugmentation using CM depends on environmental factors suitable for microbial life.

“…Despite the numerous advantages of anaerobic digestion in producing energy and treatment wastewater, the practical application of the anaerobic digestion technology is still suffering from the low conversion efficiency of organic matter to methane gas. Therefore, many attempts and techniques have been conducted in the literature to improve the process, including bioaugmentation [7], co-digestion [8], pre-treatment of waste [9], and addition of trace elements [10]. Among of these techniques, the addition of trace elements was the most used approach to enhance the anaerobic digestion process.…”

Anaerobic digestion (AD) is a well-established technology that converts organic wastes to produce renewable energy as methane gas. However, the low conversion efficiency of organic matter to methane gas is the main challenge for the practical application of this technology. Therefore, this article aims to demonstrate the effect of the addition of commercial and synthesized Fe 0 particles on methane gas production during the AD of waste sludge. Two set of experiments were conducted using two different waste sludges collected at different times from Fukuoka wastewater treatment plant in Japan. Different concentrations of commercial and synthesized iron particles were used in the anaerobic digesters ranged from 1 to 500 mg/L. The results should that the addition of the synthesized/Fe 0 particles to the anaerobic digesters improved methane production by 16% and 5% at using the first and second waste sludge, respectively. On the other hand, the addition of the commercial iron particles did not improve the production of methane gas.
