The paper develops a rapid reversed-phase LC-MS method for profiling polar metabolites, achieving high coverage and stability for 123 compounds in E. coli extracts.

The paper studies bacterial iron acquisition under low carbon conditions and finds that amino acids facilitate iron uptake by E. coli.

The paper examines how resource competition between chitin degraders and GlcNAc exploiters influences community viability and growth dynamics through factors like GlcNAc liberation rates and diffusive loss.

This study shows deep-sea microbes degrade chitin and couple it to extracellular electron transfer using syntrophic interactions in anoxic sediments.

The paper shows that EPS from chitin degradation influences microbial community diversity by supporting different consumer types through sequential breakdown.

This study introduces a method using microbial enzyme cocktails to quantify polysaccharides, demonstrating effectiveness for chitin and laminarin with low detection limits.
