Summary: The study found that cashew nut shell liquid and its phenolic compounds have inhibitory effects on the growth of most methanogenic archaea, while the propionate-producing bacteria exhibit resistance. In addition, the sensitive organisms showed altered morphology, indicating a possible surfactant-induced disruption of cell division.

Summary: The study found that microbial communities in different compartments of the aquaponic system are influenced by oxygen levels; aerobic system compartments are highly biodiverse and function primarily as nitrifying biofilters, while biofilms in anaerobic compartments contain a less diverse community.

Summary: The present study investigated the dynamic changes in fecal microbiota in donkey foals during the weaning transition. The results showed that the cessation of breastfeeding and transition to plant-based feeds increased microbial diversity and richness. The study also found an increase in cellulolytic bacteria and functions related to fatty acid and carbohydrate metabolism in post-weaning donkeys. This study contributes to a comprehensive understanding of microbiota development in donkey foals during the weaning period, which may lead to improved digestion and feed efficiency.

Summary: Methanogenic archaea are important but often ignored in studies of human and animal intestinal microbiota. This research focused on improving the quantification of methanogens using qPCR, by refining the protocol and increasing the specificity and sensitivity of the assay. The results showed increased detection range and successful validation parameters, allowing for improved detection and quantification of methanogens in stool samples, such as chicken droppings in this study.

Summary: Freshwater ecosystems play a significant role in methane emissions and this study investigated the effects of temperature on microbial community structure and methane production pathways in sub-Antarctic lake sediments. The research found that temperature had a significant impact on methane production rates, particularly when methanogenic precursors such as acetate and H-2/CO2 were introduced.

Summary: Weaning is crucial for young ruminants, as it causes significant changes in rumen function, bacterial composition, and enzyme activity. Post-weaning calves showed a more complex rumen bacteria network, higher fermentation products, and microbial protein content, but lower digestive enzyme activity compared to pre-weaning calves. These findings highlight the importance of weaning on rumen function and provide valuable insights for calf feeding management.

Summary: Methanogenic archaea are diverse microorganisms that play an important role in global carbon cycling by producing methane. Recent studies have found a high prevalence of methanogens in the host-associated microbiome of various animal species. There is increasing evidence to suggest that methanogens may have significant implications for human health and disease.

Summary: The study found that Mootral can increase the production of total volatile fatty acids and propionate in a dose-dependent manner, while reducing the proportion of acetate and acetate/propionate ratio. Additionally, Mootral significantly decreased methane production, while minimal effects were observed on pH, digestibility, and ammonia-nitrogen.

Summary: This study quantified the total numbers of bacteria, fungi and archaea in different types of commercial liquid anaerobic digestates, identifying significant differences between digestates and their physical-chemical traits. The microbial profiles of the digestates separated into just two groups, indicating a broad relative degree of similarity in terms of microbial numbers. Higher bacterial gene copy numbers were associated with low OM and C/N ratio in digestates.

Summary: This study aimed to investigate the effect of providing rumen liquid inoculum from adult cows to pre-weaning calves. The results showed that the inoculum enhanced the maturation of rumen bacterial communities in calves, but its effect on eukaryotic communities was unclear and requires further investigation.

Summary: The study reports enzymological and structural characteristics of the CO2 reduction reaction in the methanogenic pathway, revealing the mechanism of the complex using formate and F-420 electron reduction form. Conformational changes in HdrA mediate electron bifurcation, while FmdF directly transfers electrons to the CO2 reduction site, confirming the ubiquity of this complex.

Summary: Methanogenesis is a significant metabolic process carried out by methanogens in the Archaea domain. Although genes involved in methanogenic metabolism have been identified and characterized, the regulation of methane production in response to various signals remains less understood.

Summary: This study evaluated the necessity of distinguishing the physical phases of rumen contents for analyzing prokaryote communities in the rumen of lambs fed pelleted total mixed ration. The results showed that compared to the mixed phase of rumen contents, the pelleted TMR led to lower microbial DNA yield, bacterial diversity, abundances of Fibrobacterota and Spirochaetota phyla, as well as genera Ruminococcus, Lachnospiraceae_NK3A20, Fibrobacter, and F082, and the abundance of archaeal Methanimicrococcus in the rumen fluid.

Summary: Marine coastlines colonized by seagrasses are a significant net source of methane emissions, primarily driven by methylated compounds produced by the plants. Methane production continues even after the plants die off, likely due to the presence of methylated compounds in detached plant leaves and rhizomes. The study also identified gene sequences associated with key methane-producing enzymes in the seagrass sediments, suggesting their involvement in methane metabolism.

Summary: The study investigated the effects of 3-NOP and NO3- on methane production in cattle, finding that they have different mechanisms in inhibiting methane production, with the metabolic response to NO3- supplementation largely dependent on the action of NO2-.
