Environmental microbiome engineering is emerging as a potential avenue for climate change mitigation. In this process, microbial inocula are introduced to natural communities tune activities that regulate the long-term stabilization of carbon in ecosystems. review, we outline process environmental and synthesize key considerations about ecosystem functions target, means sourcing microorganisms, strategies designing inocula, methods deliver factors enable establish within resident community modify an function target. Recent work, enabled by high-throughput technologies modeling approaches, indicate designed from top-down, particularly through directed evolution, may generally have higher chance establishing existing than other historical approaches engineering. We address outstanding questions determinants establishment provide suggestions further research possibilities challenges tool combat change.

Stress-induced metabolic exchanges between complementary bacterial types underly a dynamic mechanism of inter-species stress resistance

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: May 31, 2023

Metabolic cross-feeding plays vital roles in promoting ecological diversity. While some microbes depend on exchanges of essential nutrients for growth, the forces driving extensive needed to support coexistence free-living are poorly understood. Here we characterize bacterial physiology under self-acidification and establish that excretion key metabolites following growth arrest provides a collaborative, inter-species mechanism stress resistance. This collaboration occurs not only between species isolated from same community, but also unrelated with complementary (glycolytic vs. gluconeogenic) modes metabolism. Cultures such communities progress through distinct phases growth-dilution cycles, comprising exponential acidification-triggered arrest, collaborative deacidification, recovery, each phase involving different combinations physiological states individual species. Our findings challenge steady-state view ecosystems commonly portrayed models, offering an alternative dynamical based advantages phases.

Phylogenetics and environmental distribution of nitric oxide forming nitrite reductases reveals their distinct functional and ecological roles

ISME Communications, Journal Year: 2024, Volume and Issue: unknown

Abstract The two evolutionary unrelated nitric oxide-producing nitrite reductases NirK and NirS are best known for their redundant role in denitrification. They also often found organisms that do not perform To assess the functional roles of enzymes to address sequence structural variation within each, we reconstructed robust phylogenies both proteins with sequences recovered from 6973 isolate metagenome-assembled genomes identified 32 well-supported clades structurally distinct protein lineages. We then inferred potential niche each clade by considering other genes carrying them, as well relative abundances nir gene 4082 environmental metagenomes across diverse aquatic, terrestrial, host-associated, engineered biomes. demonstrate Nir recapitulate ecology distinctly corresponding organismal phylogeny. While some reductase were equally prevalent biomes, others had more restricted ranges. Nitrifiers make up a sizeable proportion reducing community, especially marine surface waters dry soils. Furthermore, showed associations involved oxidising compounds, indicating activity may be linked different elemental cycles. Accordingly, abundance diversity vs. varies between Our results show divergent ecological NirS-encoding play environment provide phylogenetic framework distinguish traits associated encoding lineages reductases.

Competition for shared resources increases dependence on initial population size during coalescence of gut microbial communities

Proceedings of the National Academy of Sciences, Journal Year: 2025, Volume and Issue: 122(11)

Published: March 10, 2025

The long-term success of introduced populations depends on both their initial size and ability to compete against existing residents, but it remains unclear how these factors collectively shape colonization dynamics. Here, we investigate population (propagule) shapes the outcome community coalescence by systematically mixing eight pairs in vitro microbial communities at ratios that vary over six orders magnitude, compare our results neutral ecological theory. Although composition resulting cocultures deviated substantially from expectations, each coculture contained species whose relative abundance depended propagule even after ~40 generations growth. Using a consumer–resource model, show this dose-dependent can arise when resident have high niche overlap consume shared resources similar rates. Strain isolates displayed longer-lasting dose dependence into diverse than pairwise cocultures, consistent with model’s prediction should larger, more persistent effects communities. Our model also successfully predicted resource-utilization profiles, as inferred growth spent media untargeted metabolomics, would stronger coculture. This work demonstrates transient, dynamics emerge resource competition exert outcomes coalescence.

Evidence for Assimilatory Nitrate Reduction as a Previously Overlooked Pathway of Reactive Nitrogen Transformation in Estuarine Suspended Particulate Matter

Suspended particulate matter (SPM) contributes to the loss of reactive nitrogen (Nr) in estuarine ecosystems. Although denitrification and anaerobic ammonium oxidation SPM compensate for current imbalance global (N) inputs sinks, it is largely unclear whether other pathways Nr transformation exist SPM. Here, we combined stable isotope measurements with metagenomics metatranscriptomics verify occurrence dissimilatory nitrate reduction (DNRA) Pearl River Estuary (PRE). Surprisingly, conventional functional genes DNRA (nirBD) were abundant highly expressed SPM, which was inconsistent a low potential rate. Through taxonomic comparative genomic analyses, demonstrated that nitrite reductase (NirBD) conjunction assimilatory (NasA) performed (ANR) diverse alpha- gamma-proteobacterial lineages identified as key active heterotrophic ANR bacteria. Moreover, predicted have relative higher than survey across PRE spanning 65 km. Collectively, this study characterizes previously overlooked pathway mediated by bacteria has important implications our understanding N cycling estuaries.
