Metabolic interdependencies in thermophilic communities are revealed using co-occurrence and complementarity networks

Nature Communications, Год журнала: 2024, Номер 15(1)

Опубликована: Сен. 17, 2024

Microbial communities exhibit intricate interactions underpinned by metabolic dependencies. To elucidate these dependencies, we present a workflow utilizing random matrix theory on metagenome-assembled genomes to construct co-occurrence and complementarity networks. We apply this approach temperature gradient hot spring, unraveling the interplay between thermal stress cooperation. Our analysis reveals an increase in frequency of with rising temperatures. Amino acids, coenzyme A derivatives, carbohydrates emerge as key exchange metabolites, forming foundation for syntrophic which commensalistic take greater proportion than mutualistic ones. These exchanges are most prevalent phylogenetically distant species, especially archaea-bacteria collaborations, crucial adaptation harsh environments. Furthermore, identify significant positive correlation basal metabolite genome size disparity, potentially signifying means streamlined leverage cooperation metabolically richer partners. This phenomenon is also confirmed another composting system has similar wide range fluctuations. provides feasible way decipher mechanisms underlying microbial interactions, our findings suggested environmental regulates cooperative strategies thermophiles, while dependencies have been hardwired into their during co-evolutions.

Abstract The discovery of comammox Nitrospira in low pH environments has reshaped the ammonia oxidation process acidic settings, providing a plausible explanation for higher nitrification rates observed weakly soils. However, response to varying levels and its ecological role these remains unclear. Here, survey across soils with values (ranging from 4.4 9.7) was conducted assess how perform under different conditions. Results showed that dominate soils, functioning as K‐strategy species characterized by slow growth stress tolerance. As key this environment, may promote bacterial cooperation Genomic evidence suggested cobalamin sharing is potential mechanism, uniquely encode metabolic pathway compensates imbalance where 86.8% metagenome‐assembled genomes (MAGs) cobalamin‐dependent genes. Additionally, we used DNA stable‐isotope probing (DNA‐SIP) demonstrate fluctuations reflect it responds decrease pH. confirmed became dominant oxidizers soil after We will become increasingly important global trend acidification. Overall, our work provides insights changes.

Integrating multi-platform assembly to recover MAGs from hot spring biofilms: insights into microbial diversity, biofilm formation, and carbohydrate degradation

Environmental Microbiome, Год журнала: 2024, Номер 19(1)

Опубликована: Май 6, 2024

Abstract Background Hot spring biofilms provide a window into the survival strategies of microbial communities in extreme environments and offer potential for biotechnological applications. This study focused on green brown thriving submerged plant litter within Sungai Klah hot Malaysia, characterised by temperatures 58–74 °C. Using Illumina shotgun metagenomics Nanopore ligation sequencing, we investigated diversity functional metagenome-assembled genomes (MAGs) with specific focus biofilm formation, heat stress response, carbohydrate catabolism. Results Leveraging power both short-reads long-reads, employed an Illumina-Nanopore hybrid assembly approach to construct MAGs enhanced quality. The dereplication process, facilitated dRep tool, validated efficiency assembly, yielding that reflected intricate these ecosystems. comprehensive analysis uncovered intriguing insights thermophilic taxa biofilms. Moreover, examined degradation biofilms, shedding light participation diverse breakdown starch, cellulose, hemicellulose. We highlight Chloroflexota Armatimonadota exhibited wide array glycosyl hydrolases targeting various substrates, underscoring their metabolic versatility utilisation carbohydrates at elevated temperatures. Conclusions advances understanding ecology under temperature revealing adaptation from In addition, our findings biotechnology application through identification lignocellulose-degrading enzymes. By demonstrating utilising reads, value combining multiple sequencing methods more thorough exploration complex communities.
