Abstract excerpt

The biological process for phosphate (P(i)) removal is based on the use of bacteria capable of accumulating inorganic polyphosphate (polyP). We obtained Escherichia coli mutants which accumulate a large amount of polyP. The polyP accumulation in these mutants was ascribed to a mutation of the phoU gene that encodes a negative regulator of the P(i) regulon. Insertional inactivation of the phoU gene also elevated...
