Space exploration and research are uncovering the potential for terrestrial life to survive in outer space, as well environmental factors that affect during interplanetary transfer. The presence of methane Martian atmosphere suggests possibility methanogens, either extant or extinct, on Mars. Understanding how methanogens adapt under space-exposed conditions is crucial understanding implications extraterrestrial life. In this article, we discuss model organisms obtaining energy transducers producing a simulated environment. We also explore chemical evolution cellular composition growth maintenance support survival environments. Neutral selective pressure imposed components increase cell reduce physiological conditions. Energy limitation an evolutionary driver macromolecular polymerization, maintenance, fitness methanogens. Methanogens grown environment may exhibit global alterations their metabolic function gene expression at system scale. A space systems biology approach would further elucidate molecular mechanisms adaptation drastic Therefore, identifying genetically stable methanogenic community essential biomethane production from waste recycling achieve sustainable space-life functions.

Speciation in prokaryotes is often driven by complex genetic exchanges such as horizontal gene transfer (HGT), which facilitates genomic divergence and adaptation. In this study, we inferred the evolutionary transitions of mobilome (plasmids, transposons, phages) between Methanosarcina bacteria driving speciation within genus. By conducting phylogenetic analyses acetivorans, M. barkeri, mazei, siciliae, identified key elements acquired through HGT from distantly related bacterial species. These mobile have shaped plasticity, enabling to adapt diverse environmental niches potentially facilitating lineage divergence. The acquisition mobilome-associated genes involved antibiotic resistance, DNA repair, stress responses suggests their significant role ecological Methanosarcina. Overall, hypothesized that element might been subsequently established new functional homologs present lineage. This study provides insight into how mobilome-mediated flow contributes microbial populations, highlighting broader significance evolution processes.

Petroleum hydrocarbon contamination has emerged as a significant global environmental issue, severely impacting soil microbial communities and their functions. This study employed high-throughput sequencing to systematically analyze the bacterial community structure functional genes in soils with varying levels of petroleum contamination. The results demonstrated that led decline diversity, while enhancing abundance specific genes, such those involved polycyclic aromatic (PAH) degradation, methane production, denitrification. Phylogenetic analysis further revealed highly contaminated tended form clustered specialized groups, simultaneously promoting coexistence phylogenetically distant microorganisms. Mantel test identified correlations between ammonium ion concentration, moisture content, metabolic pathways, particularly related degradation These findings suggest not only disrupts carbon nitrogen metabolism balance but also profound implications for greenhouse gas emissions cycling, potentially destabilizing ecosystem. provides novel insights into ecological functions petroleum-contaminated highlights potential key factors pollution management restoration.
