WebJan 4, 2024 · Increasing the bioavailability of immobilized phosphorus (P) in soil by phosphate-solubilizing bacteria (PSB) is an effective strategy for sustainable agronomic use of P and for mitigating the P crisis. Here, D2O isotope labeling combined with single-cell Raman spectroscopy (Raman–D2O) was developed as an efficient activity-based … WebJul 28, 2024 · In the Raman spectrum of B-type carbonated apatites, the ν 1 CO 3 2– mode (at ∼1070 cm –1) overlaps the ν 3 PO 4 3– band. The latter is readily observed where the CO 3 2– content is low (up to ∼3 wt%). The CO 3 2– content of bone is considerably higher (∼7–9 wt%). As a result, the ν 3 PO 4 3– band becomes completely obscured. The …
