This paper investigates polyP metabolism in Bacillus cereus, identifying two distinct polyP pools: an intracellular PPK1-dependent pool and an extracellular pool synthesized via an unknown pathway.

This study investigates the probiotic effects of Escherichia coli Nissle 1917 and Ligilactobacillus murinus V10 in preventing Klebsiella pneumoniae sepsis in neonatal mice, showing that single-strain treatments are more effective than combinations.

The paper identifies 7 novel polyP-binding proteins in E. coli linked to translation control and ribosome biogenesis, with specific roles for YihI and Rnr.

This study uses RNA-sequencing to analyze E. coli's transcriptional response to hypothiocyanite, identifying rclB and rclC as potential regulators of membrane permeability.

This study shows that in E. coli, the stringent response and polyP synthesis jointly regulate cell division, morphology, and metabolism under non-stress conditions.

This study identifies how metal ions like Ni2+, Cu2+, and Zn2+ affect E. coli's resistance to hypothiocyanite by inhibiting key enzymes and shows the role of glutathione reductase and inorganic polyphosphate in counteracting these effects.

This study examines how Lactobacillus reuteri responds to inflammatory oxidants like H2O2 and HOCl, identifying unique resistance mechanisms that could inform microbiota-targeted therapies for gut inflammation.
