The paper identifies adenine as a cross-fed metabolite between Rhodopseudomonas palustris and E. coli, revealing a purine salvage bottleneck mechanism.

This study shows that partial denitrifying bacteria can sense and respond to denitrification intermediates they cannot use, revealing regulatory mechanisms for N2O reduction.

This study identifies oxygen depletion and nitric oxide as stimuli that trigger MSHA pilus retraction in V. cholerae via the phosphodiesterase CdpA.

The paper shows that enhanced nutrient uptake by recipient bacteria, not increased excretion by producers, drives emergent cross-feeding in microbial communities.

This study identifies E. coli genes affecting fitness in a mutualistic cross-feeding relationship with R. palustris using RB-TnSeq, revealing both expected and unexpected genetic influences.

This study shows that reductive TCA cycle enzymes and reductive amino acid synthesis pathways help maintain electron balance in a Rhodospirillum rubrum Calvin cycle mutant growing on malate or fumarate.

This study quantifies the contribution of fermentative E. coli to H2 production in coculture with R. palustris, showing E. coli contributes 32-86% depending on ammonium excretion levels.

This study shows that Rhodopseudomonas palustris uses lactate more efficiently when combined with other substrates and exhibits substrate-specific carbon catabolite control.

The paper identifies metabolic variations among honey bee gut symbionts, showing that core microbes like Gilliamella produce organic acids, potentially contributing to honey bee weight gain.

The paper identifies an E. coli nitrogen starvation response as critical for stable mutualism with R. palustris through cross-feeding.

The paper examines the spatial organization of photosynthetic membranes in purple nonsulfur bacteria, revealing species-specific patterns and their evolutionary implications.

The paper investigates how competition for a shared cross-fed nutrient affects mutualism stability between microbial partners, finding that the recipient must have a competitive advantage to maintain the mutualism.

This study identifies the genetic basis for pantothenate auxotrophy in Zymomonas mobilis, showing it is due to the absence of the panD gene and the role of IlvC in compensating for the lack of PanE.

This paper identifies a Rhizobiales-specific unipolar polysaccharide adhesin essential for biofilm formation in R. palustris under photoheterotrophic conditions but not during photoautotrophy or aerobic respiration.

The paper examines how nutrient limitation affects mutualistic bacterial cross-feeding and coexistence using experimental and theoretical approaches.
