We found that Escherichia coli grown in media with >37 mM phosphate maintained a high polyphosphate level in late stationary phase, which could account for changes in gene expression and enzyme activities that enhance ...

Many extremophilic microorganisms are polyextremophiles, being confronted with more than one stress condition. For instance, some thermoacidophilic microorganisms are in addition capable to resist very high metal concentrations. ...

© 2018 Elsevier B.V. Inorganic polyphosphates (polyP) are present in all living cells and several important functions have been described for them. They are involved in the response to stress conditions, such as nutrient ...

Inorganic polyphosphate (polyP) and its metabolic enzymes are important in several cellular processes related with virulence and antibiotic susceptibility. Accordingly, bacterial polyP synthesis has been proposed as a good ...

Formation of antimony polyphosphate using Sb2O3 and/or (NH4)2HPO4 and NH4H 2PO4 as starting materials has been simulated by thermal analysis technique. The elimination of water and ammonia molecules induced by heating leads ...
