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 addition of rumen cellulolytic bacteria and activated carbon can enhance methane production during thermophilic digestion of cornstalk, with the best performance achieved when both are present simultaneously. This improvement is attributed to the synergistic effect of the enriched bacteria working together.

Summary: This study examines the microbial diversity and characteristics of bacterial communities in volcanic glaciers in Deception Island, Antarctica, and the Kamchatka peninsula. Various glacier environmental factors were considered, and a comparative analysis of the biogeochemical cycles involving these microbiomes was attempted.

Summary: This study investigates the average genome size of planktonic prokaryotes across tropical and polar oceans and down to the hadal realm. Using hundreds of metagenomes of marine microorganisms, genome size was found to be highest in the perennially cold polar ocean, suggesting that environmental factors influence genome size selection and the ecological strategies of marine microbes.

Summary: This study investigated the impact of different fire frequencies on soil systems and found that only the A horizon was significantly affected by the prescribed fire interval manipulation. The richness and composition of microbial communities in the A horizon differed between the burned treatments and the unburned control. Soil chemistry changes were also observed in the A horizon, with higher levels of certain nutrients in the burned treatments compared to the fire exclusion treatment. The results indicate that long-term changes in fire frequencies can induce shifts in the soil microbial community.

Summary: This study investigated the microbial community and energy requirements of an anaerobic packed bed reactor treating low-strength synthetic wastewater under different HRTs and temperatures. The results showed that as the HRT and temperature decreased, COD removal and methane yield also decreased. The microbial community with low relative abundances of archaea and facultative bacteria played a significant role in the reactor's efficiency.

Summary: This study explored the key parameters of the conventional bamboo charcoal electrode to improve the power generation of microbial fuel cells (MFCs) using rumen bacteria. The surface area of the electrode was found to be the only factor affecting power generation levels, as rumen bacteria concentrated on the electrode's surface. Copper (Cu) plate and Cu paper electrodes were also tested, but their power potential decreased significantly over time due to corrosion.

Summary: The study focused on converting rice straw into biogas for energy production by employing thermophilic lignocellulolytic bacteria. Isolates with high cellulolytic and ligninolytic activities were used to degrade rice straw, resulting in significant biogas and methane yields. The optimal degradation period of 15 days led to efficient and economical biomethane production from rice straw.

Summary: Experimental findings show that cellulose, lignin, casein and oleic acid can stimulate the growth of uncultured bacteria in aquatic environments and these bacteria have the ability to degrade these organic compounds. These results provide new insights into the ecological functions and metabolic features of uncultured bacteria in aquatic environments.

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: The study reveals that the plant hormone CK plays a crucial role in the assembly of the plant microbiome, increasing richness and promoting the presence of Firmicutes. CK-mediated immunity partially depends on the microbial community, and bacilli isolated from CK-rich plant genotypes induce plant immunity and enhance disease resistance. The leaf microstructure derived from CK-rich plant genotypes supports the growth of bacilli in a biomimetic system, indicating that CK can promote the growth and biofilm formation of immune-inducing bacilli isolates.

Summary: This study reveals the importance of the gene tools that microbes use to sense their environment and regulate feed efficiency. The researchers found that animals with different feed efficiency states have different rumen microbiome composition and coding capacity. Additionally, proteomic data showed divergent protein production in microbial populations belonging to bacteria and archaea domains. These findings have significant implications for current global challenges of food security and sustainability.
