Heterosigma akashiro

The effect of starvation and the subsequent addition of phosphate-containing medium on phosphorus-containing compounds was studied by31P NMR spectroscopy of perchloric acid extracts and intact cells of Heterosigma akashiro (Watanabe et al., 1987, 1888, 1989). The PolyP content and chain length decreased under starvation and rapidly increased on P restoration in the medium (Table 8.8).
