Methane-yielding microbial communities processing lactate-rich substrates: a piece of the anaerobic digestion puzzle

Abstract: BackgroundAnaerobic digestion, whose final products are methane and carbon dioxide, ensures energy flow and circulation of matter in ecosystems. This naturally occurring process is used for the production of renewable energy from biomass. Lactate, a common product of acidic fermentation, is a key intermediate in anaerobic digestion of biomass in the environment and biogas plants. Effective utilization of lactate has been observed in many experimental approaches used to study anaerobic digestion. Interestingly,… Show more

“…In this regard, in the case of integrated DF-AD schemes, special attention must be also paid to the concentration and composition of organic acids coming from the DF stage. At this point, it should be mentioned that the redirection of carbon through HLac has been reported as a strategy to enhanced AD processes due to its thermodynamic advantages [50][51][52].…”

“…Biogas follows dark fermentation in typical anaerobic digestion process, must be inhibited (Sharma, 2019). There is some disagreement if in dark fermentation process could or could not sludge be pretreated (stressed) and methane production can occur (Detman et al, 2018;Hawkes et al, 2002). In dark fermentation process, bacterial sludge (inoculum) is usually pretreated by stressing using: heat (preheating or freezing), ultrasound or microwaves, centrifuging, chemicals, or change of pH (Muñoz-Páez et al, 2018) but works Lakaniemi et al (2011) shows that untreated raw sludge can be also successful also with hydrogen production.…”

“…The abundance of Acetobacterium and Desulfovibrio were predominant genera in AEC‐I. Acetobacterium can produces acetate as a product, while Desulfovibrio is known for its flexibility in response to the extended amount of electron acceptors including sulfate, sulfur, nitrate, and nitrite, and they are both common genus in anaerobic digestion . The abundance of Pseudomonas was only (13.6%) in AEC‐I, and its abundance further increased to 36.7% (BES‐I) and 51.7% (BES‐IP).…”
