Biomethane enhancement from corn straw using anaerobic digestion by-products as pretreatment agents: A highly effective and green strategy

Shuaishuai Ma et al.

Summary: The study demonstrated that pretreatment with CO2 and liquid digestate from anaerobic digestion can improve the glucose and xylose content of corn straw, reduce cellulose crystallinity, and increase methane yield. However, high temperature pretreatment resulted in the production of inhibitors that decreased methane production during subsequent anaerobic digestion. The changes in microbial community in the pretreated slurry at lower temperature were found to enhance the overall performance of anaerobic digestion.

Bioaugmentation with syntrophic volatile fatty acids-oxidizing consortia to alleviate the ammonia inhibition in continuously anaerobic digestion of municipal sludge

Mao-Ting Li et al.

Summary: The study revealed that utilizing syntrophic acetate and propionate oxidizing consortia as bioaugmented culture could help alleviate ammonia stress in anaerobic digestion (AD) process. Different mechanisms were found in mesophilic AD (MAD) and thermophilic AD (TAD) under ammonia inhibition. Bioaugmentation showed positive effects on microbial community and recovery time in both MAD and TAD, indicating its potential as a strategy to improve AD performance.

Lignocellulolytic microbiomes for augmenting lignocellulose degradation in anaerobic digestion

Bikram Basak et al.

Summary: Bioaugmenting lignocellulose digestion with potent lignocellulolytic microbiomes is crucial for efficient biomethanation. Evaluating the metabolic roles of these microbiomes and their interactions with the indigenous anaerobic digester microbiome is pivotal in implementing bioaugmentation. Multiple meta-omics approaches are essential for investigating gene functions, metabolic roles, and ecological niches of lignocellulolytic microbiomes.

Bioaugmentation with well-constructed consortia can effectively alleviate ammonia inhibition of practical manure anaerobic digestion

Ziyi Yang et al.

Summary: Bioaugmentation using well-constructed consortia can significantly improve methane production in anaerobic digestion. The effectiveness of bioaugmentation mainly depends on the composition of the added consortia. Well-constructed consortia can stimulate acetogenesis and methanogenesis steps, leading to a higher methane production increment. Key functional enzymes such as glycine hydroxymethyltransferase and phosphoglycerate mutase may play a critical role in the bioaugmented anaerobic digestion system.

Effect of anthraquinone-2,6-disulfonate (AQDS) on anaerobic digestion under ammonia stress: Triggering mediated interspecies electron transfer (MIET)

Jun Xu et al.

Summary: This study found that AQDS can improve the methane production and facilitate acetate production and methanation during anaerobic digestion under ammonia stress. Microbial diversity analysis revealed that AQDS can enrich electroactive bacteria. These results suggest that AQDS may enhance anaerobic digestion under ammonia stress by mediating electron transfer networks.

Pretreatment of lignocelluloses for enhanced biogas production: A review on influencing mechanisms and the importance of microbial diversity

Safoora Mirmohamadsadeghi et al.

Summary: This study critically reviewed the molecular mechanisms of different types of pretreatments on lignocellulosic biomass affecting biogas yield, proposed a new hypothesis regarding the influence of pretreatments on microbial communities, and experimentally verified it through a case study. The findings emphasized the significant role of pretreatment methods in altering the microbial community and subsequently impacting biogas production from lignocelluloses. These results challenge the default hypothesis of changes in substrate characteristics as the sole mechanism affecting biogas yield, and provide insights for developing more efficient biogas production systems at an industrial scale through a deeper understanding of microbial community interactions.

Synergistic association between cytochrome bd-encoded Proteiniphilum and reactive oxygen species (ROS)-scavenging methanogens in microaerobic-anaerobic digestion of lignocellulosic biomass

Zhuoying Wu et al.

Summary: Intermittent microaerobic digestion of lignocellulosic biomass at a high organic loading rate showed higher digestibility and better stability compared to strict anaerobic conditions. The study identified efficient cellulolytic facultative bacterium and methanogens as key players in maintaining the delicate balance under microaeration. Additionally, cytochrome bd oxidase and antioxidant enzymes were found to potentially improve digestibility and stability in intermittent microaerobic digestion.

Anaerobic co-digester microbiome during food waste valorization reveals Methanosaeta mediated methanogenesis with improved carbohydrate and lipid metabolism

Swapnil M. Patil et al.

Summary: The study found that low food waste loading in anaerobic digesters can increase methane production, while high loading can lead to extended lag phase and incomplete substrate utilization. The degradation rate of LCFAs is influenced by the initial FW loading, with up to 99% degradation rate at 4% FW reactor, while adding 8 to 10% FW substrate inhibits methane production.
