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 approach to
characterizing the presence and activity of PSB in a culture-independent way. On the basis
of the finding that PSB were significantly more active than non-PSB in the presence of …
