Costless metabolic secretions as drivers of interspecies interactions in microbial ecosystems

Nature Communications, Journal Year: 2019, Volume and Issue: 10(1)

Published: Jan. 3, 2019

Abstract Metabolic exchange mediates interactions among microbes, helping explain diversity in microbial communities. As these often involve a fitness cost, it is unclear how stable cooperation can emerge. Here we use genome-scale metabolic models to investigate whether the release of “costless” metabolites (i.e. those that cause no cost producer), be prominent driver intermicrobial interactions. By performing over 2 million pairwise growth simulations 24 species combinatorial assortment environments, identify large space secreted without thus generating ample cross-feeding opportunities. In addition providing an atlas putative interactions, show anoxic conditions promote mutualisms by more opportunities for costless metabolites, resulting overrepresentation ecological network motifs. These results may help interaction patterns natural communities and inform design synthetic consortia.

Toxicity drives facilitation between 4 bacterial species

Proceedings of the National Academy of Sciences, Journal Year: 2019, Volume and Issue: 116(32), P. 15979 - 15984

Published: July 3, 2019

Competition between microbes is extremely common, with many investing in mechanisms to harm other strains and species. Yet positive interactions species have also been documented. What makes help or each currently unclear. Here, we studied the 4 bacterial capable of degrading metal working fluids (MWF), an industrial coolant lubricant, which contains growth substrates as well toxic biocides. We were surprised find only neutral Using mathematical modeling further experiments, show that this community likely due toxicity MWF, whereby species' detoxification benefited others by facilitating their survival, such they could grow degrade MWF better when together. The addition nutrients, reduction toxicity, more instead resulted competitive behavior. Our work provides support stress gradient hypothesis showing how harsh, environments can strongly favor facilitation microbial mask underlying interactions.

Trophic Interactions and the Drivers of Microbial Community Assembly

Current Biology, Journal Year: 2020, Volume and Issue: 30(19), P. R1176 - R1188

Published: Oct. 1, 2020

Despite numerous surveys of gene and species content in heterotrophic microbial communities, such as those found animal guts, oceans, or soils, it is still unclear whether there are generalizable biological ecological processes that control their dynamics function. Here, we review experimental theoretical advances to argue networks trophic interactions, which the metabolic excretions one primary resource for another, constitute central drivers community assembly. Trophic interactions emerge from deconstruction complex forms organic matter into a wealth smaller intermediates, some released environment serve nutritional buffet community. The structure emergent network rate at resources supplied many features assembly, including relative contributions competition cooperation emergence alternative states. Viewing assembly through lens also has important implications spatial communities well functional redundancy taxonomic groups. Given ubiquity across environments, they impart common logic can enable development more quantitative predictive ecology.

Soil Microbiomes Under Climate Change and Implications for Carbon Cycling

Annual Review of Environment and Resources, Journal Year: 2020, Volume and Issue: 45(1), P. 29 - 59

Published: June 2, 2020

Communities of soil microorganisms (soil microbiomes) play a major role in biogeochemical cycles and support plant growth. Here we focus primarily on the roles that microbiome plays cycling organic carbon impact climate change cycle. We first discuss current challenges understanding carried out by highly diverse heterogeneous microbiomes review existing knowledge gaps how will microbiome. Because stability is key metric to understand as changes, different aspects stability, including resistance, resilience, functional redundancy.We then recent research pertaining perturbations functions they carry out. Finally, new experimental methodologies modeling approaches under development should facilitate our complex nature better predict its future responses change.
