The influence of enrichment culturable microorganisms in situ coal seams on biomethane production potential other has been rarely studied. In this study, we enriched from three with ranks and conducted indoor anaerobic experiments. Microbial community composition, gene functions, metabolites different culture units by 16S rRNA high-throughput sequencing combined liquid chromatography-mass spectrometry-time-of-flight (LC-MS-TOF). results showed that the bituminous group (BC)cc resulted highest methane yield 243.3 μmol/g, which was 12.3 times higher than control (CK). Meanwhile, Methanosarcina dominant archaeal genus experimental groups (37.42 ± 11.16-52.62 2.10%), while its share CK only 2.91 0.48%. Based functional annotation, relative abundance genes mainly related to metabolism nitrogen-containing heterocyclic compounds such as purines pyrimidines. Metabolite analysis promoted degradation a total 778 organic substances coal, including 55 significantly (e.g., pyrimidines). genomic metabolomic analyses, paper reconstructed coupled pathway thereby preliminarily elucidated bacteria coal-rank could promote intensify biogenic yields.

By allowing coal to be converted by microorganisms into products like methane, hydrogen, methanol, ethanol, and other products, current deposits can used effectively, cleanly, sustainably. The intricacies of in situ microbial degradation must understood order develop innovative energy production strategies economically viable industrial mining. This review covers various forms conversion (such as the use MECoM, which converts hydrogen), stresses, use. There is ongoing discussion regarding effectiveness field-scale pilot testing when translated commercial production. Assessing applicability long-term viability MECoM technology will require addressing these knowledge gaps. Developing suitable nutrition plans utilizing lab-generated data field are examples this. Also, we recommend directions for future study maximize methane from coal. Microbial needs successful resolved a viable, sustainable source.

Microorganisms can affect coal biodegradation by driving elemental biogeochemical cycling. A detailed description of the sulfur conversion process led indigenous bacteria during degradation is important. This study obtained sulfur-containing compounds through indoor enrichment and conducted anaerobic culture experiments using supplemented with enriched bacteria. The showed that addition changed microbial composition, particularly groups within Pseudomonadota Bacillota. In addition, increased pore volume specific surface area micropores (<10 nm) transition pores (10–100 nm), as well content organic components including polypeptides, aromatic compounds, alkyl thiazoles. genera related to inorganic were mainly belonging Bacillota Actinomycetota. Additionally, functional degrade dibenzothiophenes ring-opening benzene rings found Pseudomonadota, summary, sulfur-related Actinomycetota detected in this could accelerate ultimately increase coal, holds great significance for understanding cycling coal.
