This study measures ion thresholds for phage infection and shows that phage impact on terrestrial microbiomes is strongest in high-ion environments with simple carbon sources.

The paper creates a mutant fitness compendium for Bifidobacterium breve to identify molecular factors affecting colonization and host-microbe interactions.

This study evaluates how different inoculation practices and harvesting times affect microbial community reproducibility in a fabricated ecosystem with Brachypodium distachyon.

The paper develops a chemically-defined medium that supports the growth of both Lactobacillus and Acetobacter bacteria, enabling the study of their metabolic interactions.

The paper measures kinetic parameters of sulfate adenylyl transferase and compares inhibitor potency with growth inhibition in sulfate-reducing bacteria.

This paper identifies a novel cobamide remodeling enzyme, CbiR, in Akkermansia muciniphila that enables the bacterium to use diverse cobamides by modifying their structure.

This paper identifies genes essential for Ralstonia spp. growth in tomato xylem sap using RB-TnSeq, revealing envelope-related factors critical for survival in this niche.

The paper investigates how different carbon sources affect the end-products of nitrate respiration in microbial communities from diverse environments.

This study systematically measures mutant phenotypes for genes in Bacteroides thetaiotaomicron to uncover gene functions and improve understanding of gut microbiota physiology.

The paper identifies novel oxidative pathways for deoxyribose and deoxyribonate catabolism in bacteria using genome-wide mutant fitness assays and genetic evidence.

The paper identifies toxic inorganic ions that inhibit sensitive microorganisms and favor Rhodanobacter in a metal-contaminated aquifer.
