Fig. 3. Temporal growth profiles of G. sulphuraria in Test I in cyanidium medium
prepared as follows: (a) in nanopure water; (b) in sterilized primary-settled
wastewater; and (c) in unsterilized primary-settled wastewater. In all cases, initial
N was adjusted to 40 mg L1 and initial phosphate to 10 mg L1. Error bars indicate
SD from triplicates. Inset shows growth rates estimated from the growth curves
with std. dev.
