“…Moreover, Arias et al (2021) evaluated the degradation of swine waste and corn straw at a temperature of 35 °C and obtained a biogas yield close to that found in this study for the best reactor supply condition, with 674 L kg −1 applied VS. Table 4 shows some unit relationships related to the P3 treatment. Contrary to what has been reported by Wei & Guo (2018) and Lendormi et al (2022), the biogas production for this study in the mesophilic range was considered superior to the psychrophilic range. However, the high production of biogas at the temperature of 18 °C stands out; in practical terms, the recovery of biogas as an energy source is already advantageous.…”

“…Wei & Guo (2018) studied the co-digestion of swine waste, barley straw, and bovine manure at temperatures of 15 and 35 °C and obtained a production of 0.225 and 0.246 m 3 biogas kg −1 VS, indicating a similar biogas production for the two temperatures under study. Lendormi et al (2022) observed that the biogas production after acclimatization of swine manure in a reactor operated at 13 °C was 0.222 m 3 biogas kg −1 applied COD, which corresponded to 68% of the biogas production for the temperature of 37 °C.…”

Anaerobic digestion (AD) stands out as a degradation pathway for the treatment of agroindustrial waste. This study aimed to evaluate the biogas production (Pb) from the codigestion of swine (SW) and laying hen waste (LHW) under different temperature conditions (psychrophilic x mesophilic). The studies were carried out on a laboratory scale in anaerobic reactors (1.25 L) in a batch system for 60 days. Three mixtures in volumetric proportions (%) of 25/75 (P1), 50/50 (P2), and 75/25 (P3) (SW/LHW) were studied. The mixtures were characterized before and after AD in terms of TS, VS, and COD under temperatures of 18 and 36 °C, with Pb measured daily. Pb was higher at 36 °C for all mixtures compared to the psychrophilic condition (18 °C). Among the mixtures, the highest Pb value was observed for P3, reaching 0.34 and 0.60 m 3 biogas kg −1 CODremoved for 18 and 36 °C, respectively. The digestate showed an increase in the contents of micro-and macronutrients for P1, P2, and P3 after AD, which indicates its use for agricultural purposes. The co-digestion of swine and laying hen waste is a promising proposal in terms of management and energy recovery of biogas, especially for mesophilic conditions in mixtures with a predominance of laying hen waste.

“…A study presented by Sommer et al showed that fresh cattle slurry incubated at 20 • C with adapted inoculum took more than 100 days of lag phase before starting to emit significantly [24]. Additionally, a recent study from Lendormi et al regarding acclimation of microbial community to psychrophilic anaerobic digestion showed that among five swine manure samples, the most efficient took 2 months of storage to acclimate [63]. The methanogens present in fresh dairy manure in our study, from rumen, may have not adapted to the conditions of the environment, and the low methane emissions were verified.…”

Livestock production contributes to releasing methane into the atmosphere. Liquid manure management offers significant opportunities to reduce these emissions. A better understanding of the factors controlling methane emissions from manure is necessary to select effective mitigation strategies. Our study aimed to identify the influence of storage temperature and the associated change in chemical composition on methane emissions from dairy and fattening pig manure. Storage temperature affects microbial activity and induces changes in chemical composition that are key influences in methane emissions. Dairy and fattening pig manure samples were stored at five different temperatures (5–25 °C) for 90 days in a laboratory-scale experiment to measure the methane production. The chemical composition of the slurry samples was analyzed, and the biochemical methane potential (BMP) tests were performed before and after storage. For pig manure stored at 25 °C and 20 °C, methane emissions accounted for 69.3% and 50.3% of the BMP, respectively. Maximum methane emissions for dairy slurry were observed at 25 °C but remained at a low level. Analyses of the accumulation of volatile fatty acids (VFAs) during storage are presented in few studies, this work revealed a potential inhibition of methane production, where the accumulation of VFAs was most elevated in samples stored at 20 °C and 25 °C. This partly counteracted the increase in methane emissions expected from the higher temperatures. The degree of VFA and dissociated fatty acids accumulation in dairy cattle slurry should be assessed for more accurate estimations of methane emissions from slurry stores.

“…In the experimental group with butyric acid as a substrate ( Buty 0 , Buty 1.5 ), the abundance of Candidatus_Cloacimonas increased by 2.3 and 2.9 times, respectively. Studies have shown that Candidatus_Cloacimonas has the function of homoacetogenic producing; moreover, the abundance of the recognized butyric acid-degrading bacterium Syntrophomonas did not decrease under the condition of inhibitory ammonia stress ( Buty 0 , 1.29%; Buty 1.5 , 1.3%), indicating that it did not affect the microbial community abundance of butyric acid-degrading bacteria at the ammonia nitrogen concentration of 1.5 g N/L.…”

Nitrogenous organic matter could be converted into ammonia nitrogen during anaerobic digestion (AD) which could lead to the inhibition of methane production. Therefore, it is crucial to investigate the effect of ammonia stress on AD. In this study, the addition of ammonia nitrogen concentration of 1.5 g N/ L led to an obvious extended lag-period time of the AD with propionic acid or n-butyric acid as the sole substrate, while it showed no effect on the AD of acetic acid, indicating that the biotransformation of propionic acid and butyric acid might be more susceptible under low inhibitory ammonia stress. Analysis of the microbial consortia revealed that the community composition of bacteria and archaea was not obviously affected by a low inhibitory ammonia stress. Metatranscriptomic analysis showed that the enzymes related to the biotransformation of propionic and butyric acids were more susceptible to ammonia toxicity than those corresponding to acetoclastic methanogenesis. During protein synthesis, the expression of RNA polymerase and the subunits of ribosomes, which affected the transcription process, were significantly down-regulated. Additionally, ammonia toxicity caused DNA damage in microorganisms and triggered the SOS response of microorganisms. This study provided new insights for further understanding of the mechanism of ammonia stress at a low inhibitory level.
