“…The results demonstrated that WS6_Dojkabacteria was the genus most sensitive to environmental factors, and that it had a negative relationship with CN, UV 254 , ammonia nitrogen, and total nitrogen. Previous studies indicated that WS6_Dojkabacteria was an obligate fermenting bacteria that played a key role in organics degradation (Campanaro et al, 2020; Sánchez‐Osuna et al, 2017; Zhou et al, 2020, 2021). Therefore, the higher proportion of this bacteria in group IL was another reason for the better organic degradation efficiency observed in this group.…”

In practice, mature landfill leachate and incineration (young) leachate are mixed to improve the biodegradability and enhance biological treatment performance. However, the ratio of mature‐to‐young leachates greatly influences MBR treatment efficiency and microbial community structure. This study investigated the treatment efficiency and microbial community structure of full‐scale MBR systems operated under two mix ratios, mature leachate: young leachate = 7:3 (v/v, denoted as LL) and 3:7 (v/v, denoted as IL). LL group showed lower Cl− and COD concentrations but a higher aromatic organic content comparing to IL group, and the COD and UV254 removals for LL were significantly lower than those for IL by MBR treatment. Microbial community structures were similar in both groups at phylum level, with dominant phyla being Proteobacteria (23.8%–32.3%), Bacteroidetes (15.25%–20.7%), Chloroflexi (10.5%–23.1%), and Patescibacteria (9.9%–13.2%). However, the richness and diversity of LL group were lower, and differences were observed at lower taxonomy levels. Results indicated that salinity mainly changed the structure of microbial community, resulting in greater abundance of salt‐tolerant microbials, while refractory organics affected microbial community structure, and also led to decreased diversity and metabolic activity. Therefore, in mixed leachates biological treatment, a higher young leachate ratio is recommended for better organics removal performance. Practitioner Points The trade‐off between refractory organics and salinity in mixed leachate treatment should be paid attention. Refractory organics reduced alpha and functional diversities of microorganisms. Mixed leachate with a higher young leachate ratio reached a better organic removal.

Anaerobic co-digestion (AcoD) is becoming increasingly popular in the biogas industry for its numerous advantages over mono-digestion, including balanced nutrient profiles, enhanced process stability, synergistic methane production, and reduced greenhouse gas emissions. However, varying results across AcoD studies highlight the need for an extensive meta-analysis of a large data set to better understand these synergies. Here, we compared methane yields from 432 data sets, based on the ratio of means, from AcoD and mono-digestion. The relative synergistic index (RSI) revealed synergistic effects in AcoD of lignocellulosic biomass with animal manures, particularly pig (RSI = 1.91) and chicken manures (RSI = 1.71). Due to its rapid biodegradability, food waste AcoD also demonstrated synergistic effects with both animal manures (RSI = 1.28) and lignocellulosic biomass (RSI = 1.41). After regrouping data by high-carbon cosubstrates, interpretable machine learning models identified temperature, which accelerates the hydrolysis of lignocellulosic biomass and emulsification of fats, oils, and grease, as the key factor influencing methane yield. Furthermore, experimental validation using food waste and sewage sludge co-digestion confirmed the superiority of multivariable linear regression in predicting specific methane yield over other models in terms of simplicity and efficiency.
