Summary: Through ecological interactions with various biotic and abiotic agents in soil ecosystems, diverse soil microorganisms establish complex and stable communities in natural settings. These microbial interactions drive soil microbes to function as the major engine of terrestrial biogeochemical cycling, and play an instrumental role in promoting soil health through bioremediation of pollutants and biocontrol of soil-borne phytopathogens.

Summary: Rubber biodegradation is still understudied due to its high stability and the lack of well-defined pathways and efficient enzymes. However, eco-friendly solutions are required in light of the environmental issues caused by rubber products. Extensive studies have been conducted on the enzymes and cleavage mechanisms involved in poly (cis-1,4-isoprene) rubber degradation, but relatively few studies have been conducted on natural rubber (NR) degrading bacterial consortia. Using multi-omics tools is proposed as a primary research direction to understand the mechanisms of rubber degradation and develop synthesized microbial consortia.

Summary: This study demonstrates the impacts of different lignocellulose substrates and exposure times on long-term bacterial community assembly and identifies comprehensive potential decomposers at the levels of taxa and functional genes. The links between ligninolytic functional traits and taxonomic groups of substrate-specific populations are revealed. It shows that the synergistic effect of lignin and hemi-/cellulose degradation could enhance lignocellulose degradation under alternation of aerobic and anaerobic conditions. This study provides valuable taxonomic and genomic insights into coastal bacterial consortia for lignocellulose degradation.

Summary: In this study, the microbial composition and function of microbial consortium M44 with straw degradation during subculture at low temperature were explored. The degradation characteristics of straw in different culture stages were determined, and the community structure evolution and its relationship with degradation characteristics were analyzed using high-throughput sequencing technology. The results provided insight into the microbial community succession and gene function in different culture periods, which can be used as a theoretical basis for screening and rational utilization of microbial consortia.

Summary: This study screened four microbial consortia capable of degrading lignin from decayed wooden antiques, with J-6 showing the highest lignin degradation efficiency. The fungal consortium of J-6 was mainly composed of Saccharomycetales, while the bacterial consortium included Shinella sp., Cupriavidus sp., and Bosea sp. The superior performance of J-6 can be attributed to the synergistic effects of its microbial composition.

Summary: In this study, a thiosulfate-driven denitratation system was successfully established with high nitrite accumulation efficiency. Thiosulfate preferred the reduction of nitrate over nitrite, but after depletion, sulfur served as the main electron donor favoring nitrite reduction and constraining nitrite accumulation. Metagenomic sequencing identified key microbe species and metabolic pathways contributing to high NAE in the TDD system.

Summary: Two bacterial consortia capable of degrading alkali lignin were enriched from nearshore sediments of the East and South China Seas. These consortia could produce ligninolytic enzymes and degrade lignin and its derivatives through multiple pathways. This study highlights the significant role of bacteria in lignin degradation and their contribution to the oceanic carbon cycle.

Summary: Lignocellulosic wastes, such as brewery spent grain (BSG), hold potential as valuable resources for biorefinery purposes. Enhancing the degradation of these recalcitrant feedstocks can be achieved through bioaugmentation with specialized microbial consortia. In this study, six different sources of mixed microbial consortia were screened for their ability to improve the production of chemicals (volatile fatty acids or ethanol) and energy (biogas) from BSG. The results showed that anaerobic granular sludge was the most effective inoculum for solids destruction and gas production, while rhinoceros and tiger manure resulted in the highest accumulation of volatile fatty acids. However, further research is needed to identify the inhibitors of hydrolysis and improve BSG degradation.

Summary: The advancement of omics-based approaches and next-generation sequencing has revealed the principles underlying the interaction between plants and the microbiome. Although challenging, it is becoming easier to relate individual taxa in a microbiome to their function. The knowledge of plant microbiome, especially the functional microbiome, has opened new avenues for formulating biofertilizers based on consortia of plant growth-promoting strains.

Summary: The recirculation of solid digestate with ligninolytic aerobic consortia did not increase methane recovery during the short-term aerobic post-treatment. The decrease in methane yields was attributed to the respiration of easily degradable fractions by the selected consortia.

Summary: Microbially mediated inorganic-methylated arsenic transformation is crucial to rice safety. Bacteria harbor the most genes related to arsenic biotransformation, and some bacteria contain both arsM and arsI genes. The presence of the methylated arsenic pool and the arsenic methylation-demethylation cycle should be considered in paddy fields for rice safety.

Summary: This study compares the effects of conventional padding and straw waste on ectopic fermentation systems (EFS) of pig manure. The results showed that using straw waste can enhance the degradation rates of cellulose, hemicellulose, and lignin, and have a stronger impact on bacterial community succession. The abundances of Sphingobacterium, Pseudomonas, and CAZymes were higher in the straw waste group, which promotes lignocellulose degradation.

Summary: This study evaluated the changes in the rhizosphere microbiome of Lolium perenne during the phytoremediation of soils contaminated with mercury and cadmium. Results showed that mycorrhizal inoculation influenced the absorption and distribution of metals, and the Enterobacteriaceae family exhibited biosorption and efflux effects on mercury and cadmium. Overall, Lolium perenne has high potential for phytoremediation of Cd- and Hg-contaminated soils in the tropics, and mycorrhizal inoculation and changes in the microbiome can enhance plant tolerance to these metals.
