“…For anaerobic bioreactors, the theoretical maximum methane production is 350 mL of CH 4 /gCOD and can be computed based on the stoichiometry of methane produced from a mole of organic matter mineralization (Rincón-Catalán et al, 2022). The BMP value in our EGSB bioreactor was similar to previously reported values in other anaerobic bioreactors (Labatut et al, 2011;Mainardis et al, 2017;Rincón-Catalán et al, 2022). Finally, the EGSB bioreactor is a low-cost and robust technology compared to other types of bioreactors.…”

“…These high nutrient levels promote eutrophication in receiving waters, particularly in lakes and slow-moving rivers (Prazeres et al, 2012). Therefore, the discharge of this type of wastewater into bodies of water could cause various problems in water quality, such as rapid proliferation of toxic phytoplankton and algae, aesthetic pollution, loss of plant and animal diversity, alterations in abundance and distribution of microbial communities, oxygen depletion, and potential mortality of higher organisms due to neurotoxins (Prazeres et al, 2012;Osorio-González et al, 2018;Rincón-Catalán et al, 2022).…”

“…Therefore, BMP reflects the activity of the anaerobic microbial community (i.e., catabolism and fermentation) and depends on the proportion of biodegradable substances and the chemical composition of these compounds (Michaud et al, 2002). For anaerobic bioreactors, the theoretical maximum methane production is 350 mL of CH 4 /gCOD and can be computed based on the stoichiometry of methane produced from a mole of organic matter mineralization (Rincón-Catalán et al, 2022).

“…In the cheese-making process, between 8 and 9 liters of cheese whey are generated for every kilogram of cheese produced (Asunis et al, 2019), resulting in a worldwide production of around 211.3 million m 3 /year. Therefore, cheese whey is considered the main by-product of the cheese agro-industry but also one of the main sources of waste and environmental pollution (Rincón-Catalán et al, 2022). The composition and physicochemical properties of cheese whey wastewater (CWW) generally depend on manufacturing practices used in cheese-making and other dairy processes (Carvalho et al, 2013).…”

The cheese-making process generates large amounts of cheese whey wastewater (CWW), which is abundant in nutrients but difficult to dispose of, contributing to the eutrophication of natural environments due to inadequate waste management. Here we show the anaerobic digestion of CCW by syntrophy between bacteria and archaea in an expanded granular sludge bed (EGSB) bioreactor as a low-cost alternative for bioremediation and biofuel production. The performance of the EGSB bioreactor and the composition of the natural microbial community were evaluated. During the operation of the EGSB bioreactor, physicochemical parameters such as alkalinity ratio (0.25), pH (7.5), and temperature (26°C) were attained and maintained, as well as light- and oxygen-free conditions, which favored the metabolism of oxygen-sensitive bacteria and methane-producing archaea (methanogens). Under these conditions, the chemical oxygen demand (COD) removal rate was highly efficient (> 89%). Methane (CH4) was produced from organic matter degradation by a few methanogens, mainly from Methanosaeta spp., and was enhanced by the metabolic interaction between bacteria and archaea. The biochemical methane potential (BMP) was >335 mL CH4/gCOD, indicating that the syntrophic microbial community is very efficient in removing organic matter and CH4 produced from CWW. Our results suggest that CWW could be treated in EGSB bioreactors and used as a sustainable alternative to CH4 production and also provide insights for the design of synthetic microbial communities (SynComs) for bioremediation, biogas production, and other biotechnological processes.

“…The result of the biochemical methane potential (BMP) tests showed methane yields of 0.51-0.60 L CH4/g TVS added. Other researchers reported a BMP value of 338.9 mL CH4/g COD from cheese whey treatment by anaerobic digestion [14]. Cheese way fraction can reach up to 60 % of the substrate if digested with ca le manure as performed by Bella and Venkateswara Rao [15] who obtained the highest biogas production (342.22 mL/gVS).…”

The dairy and meat industries generate thousands of tons of organic waste and by-products each year, making them two of the least environmentally sustainable sectors. Typical waste includes not only processing by-products such as curds but also commercial products that are defective or unsaleable due to expiration or damaged packaging. This study aimed to evaluate the methanogenic potential of a mixture of 80% inedible curds and 20% expired sausages, as a substrate, using two continuously stirred tank reactors (CSTR). The reactors were fed daily with increasing doses of the 80–20% mixture and an organic loading rate ranging from 0.31 gVS/litre/day at the beginning of the trials to 7.20 gVS/litre/day toward the end. The produced biogas was continuously analysed from both quantitative and qualitative point of view. Also, the process was continuously monitored by withdrawing samples from each reactor during the whole process, to analyse their physical–chemical parameters, including pH, total solids (TS), total volatile solids (TVS), chemical oxygen demand (COD), ammonium nitrogen (NH4⁺-N), total Kjeldahl nitrogen (TKN) and total volatile fatty acids (VFA). The results of this study show a promising increase in biogas production with the increase in feed. In terms of biogas production, organic waste from the dairy and meat industry shows the potential to be exploited as a substrate to produce biomethane. Indeed, in this study, biomethane cumulative production reached 410.86 NLCH4∙gTVS−1 using an 8 L capacity reactor filled up to 6 L. This makes the tested by-products usable as a renewable energy source in the future, particularly within a circular economy approach, helping to mitigate the effects of global warming and addressing sustainable development goals.
