The incorporation of P/sup 32/ in Vibrio cells is stimulated by glucose and inhibited by chloromycetin, dinitrophenol, azide, and copper ions. In the trichloracetic acid-insoluble fraction, P/sup 32/ is shared mostly by phospholipids and nucleic acids. Larger doses of ultraviolet radiation are required to inhibit the P/sup 32/ incorporation in the nongrowing cells. Incorporation of P/sup 33/ in the growing cultures, however, is affected even at lower doses, and the effect is more pronounced in the DNA fraction. It was suggested that P/sup 32/ incorporation may be through macromolecular turnover in the nongrowig cells, which appears to be relatively insensitive to ultraviolet irradiation as compared to the net synthesis in the growing cultures.
