The roles and synthesis of inorganic polyphosphate in Bacillus cereus

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.

Probiotic biogeography and sepsis prevention in the neonatal intestine

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.

Inorganic polyphosphate and the stringent response coordinately control cell division and cell morphology in Escherichia coli

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