In our study on the growth curves of C.vulgaris, He et al. (2013)
found that the cell density of C. vulgaris correlated positively with
NHþ4
–N concentration at 29–174 mg/L TN; that the peak value of
cell density (1.86 g/L) was reached at 174 mg/L TN; and that the
growth of C.vulgaris was inhibited at 246 mg/L TN, at a cell density
of 0.9 g/L.
