Phosphatase hydrolysis
WebSequential fractionation with H 2 O, 0.5 M NaHCO 3, and 0.1 M NaOH and phosphatase hydrolysis were used to monitor changes in inorganic P and enzymatically hydrolyzable and nonhydrolyzable organic P during the incubation period. Similar patterns of P dynamics were observed in the two soils. Added inorganic P from either chemical fertilizer or ... WebOur 7-hydroxy-9H-(1,3-dichloro-9,9-dimethylacridin-2-one (DDAO phosphate, D6487) phosphatase substrate yields a hydrolysis product that is efficiently excited by the 633 nm spectral line of the He-Ne laser to produce bright red fluorescence with absorption/emission maxima of ~646/659 nm (Figure 10.3.1).
