Microbial communities experience environmental fluctuations across timescales from rapid changes in moisture, temperature, or light levels to long-term seasonal climactic variations. Understanding how microbial populations respond these is critical for predicting the impact of perturbations, interventions, and climate change on communities. Since typically harbor tens hundreds distinct taxa, response abundances perturbations potentially complex. However, while taxonomic diversity high, many taxa can be grouped into functional guilds strains with similar metabolic traits. These effectively reduce complexity system by providing a physiologically motivated coarse-graining. Here, using combination simulations, theory, experiments, we show that nutrient depends timescale those fluctuations. Rapid drive cohesive, positively correlated abundance dynamics within guilds. For slower variation, members guild begin compete due resource preferences, driving negative correlations between same guild. Our results provide route understanding relationship community changing environments, as well an experimental approach discovering via designed

Abstract Microalgae‐bacteria systems present a promising approach for CO 2 reduction in wastewater treatment. The effect of inoculation bacteria‐algae ratio on performance was investigated this study. Different ratios (bacteria: algae 1:2, 1:1, 1:0.5, 1:0.25, 1:0.125, w/w) obtained comparable nutrients removal (p > 0.05). Over time, the converged into two groups (3:1 and 4:1), demonstrating self‐adaption between bacteria microalgae. Furthermore, principal component analysis (PCA) distinguished reactors groups, one group consisting 1:0.5 other 1:0.25 1:0.125 ratios, confirming their convergence terms nutrient photosynthetic properties. differed merely sludge volume index (SVI) nitrite accumulation, with 1:2 being most prone to accumulate nitrite. This study implies that photobioreactor not sensitive ratio, whose role overestimated, since microalgae self‐assemble form niches. Practitioner Points Effect overestimated Photosynthesis were grouped at different showed similar efficiency Self‐adaption made converge 3:1

The metabolic activity of microbial communities is central to their role in biogeochemical cycles, human health, and biotechnology. Despite the abundance sequencing data characterizing these consortia, it remains a serious challenge predict traits from alone. Here we culture 96 bacterial isolates individually assay ability grow on 10 distinct compounds as sole carbon source. Using well two existing datasets, show that statistical approaches can accurately utilization genomes. First, classifiers trained gene content phenotypes by encoding phylogenetic information. These models substantially outperform predictions made constraint-based automatically constructed This result solidifies our current knowledge about strong connection between phylogeny traits. However, phylogeny-based fail for taxa are phylogenetically distant any strains training set. To overcome this train improved presence/absence content. We generalize set either exploiting biochemical information feature selection or having sufficiently large datasets. In latter case, provide evidence approach identify putatively mechanistic genes involved Our study demonstrates potential power predicting genotypes using approaches.
