Pi content of extracted acid-soluble polyphosphates (ASPPs) from Microbispora sp. biomass (A) and transcriptional profile of selected Microbispora sp. pho genes (B) in P0.1 (light gray bars), P0.5 (dark gray bars) and P5 (black bars) media. Minimum and maximum relative values, calculated from three independent experiments, are reported as error bars. Relative values were normalized using hrdB gene as endogenous gene.
