WebThe tripolyphosphate content was also controlled by the availability of inorganic phosphate during cell growth. Phosphate-depleted D. salina contained no detectable tripolyphosphate signal. Excess phosphate, however, did not result in the appearance of tripolyphosphate in (31)P-NMR spectra of cells adapted to high (>1.5 molar NaCl) salinites. WebCurrently, 31P NMR is the only analytical method that quantitatively determines the average chain length of long inorganic polyphosphate (>80 P-subunits). In this study, an enzyme assay is presented that determines the average chain length of polyphosphate in the range of two to several hundred P-subunits. In the enzyme assay, the average polyP chain length …
