Uring days six below HP circumstances (Figure 2A) when continuingly decreased beneath LP conditions. The final concentrations of nitrate ( ol L-1 ) UCB-5307 Purity & Documentation inside the four scenarios were 11.77 2.15 (HNHP), 11.40 0.85 (HNLP), 9.20 0.51 (LNHP), and 9.10 0.46 (LNLP). Phosphate was consumed swiftly inside the first three days under all scenarios, reaching the amount of detection (0.05 ol L-1 ) by day 3 beneath LP and day 6 beneath HP conditions (Figure 2B). However, ammonium decreased from day three (5.28.09 ol L-1 ) to day six (two.45.69 ol L-1 ) just after an initial gradual raise, then improved to four.61.02 ol L-1 (Figure 2C). The sum of nitrate and ammonium (DIN) is shown in Figure 2D. A surplus of DIN was identified in all the scenarios in the end with the experiment (Figure 2D). The 4 scenarios showed varying nutrient uptake prices (pmol cell-1 d-1 ), defined as net damaging nutrient concentration changes (Equation (three)), within the three measurement stages (days 0, three, and six). Maximum DIN uptake rates have been observed inside the first stage (0.600 0.127 (HNHP), 0.937 0.180 (HNLP), 0.334 0.211 (LNHP), and 0.416 0.Water 2021, 13,6 of(LNLP)) (Figure 3A). DIN uptake prices decreased in stages two and three (Figure 3A). Maximum phosphate uptake rates have been also observed within the 1st stage (0.108 0.035 (HNHP), 0.037 0.002 (HNLP), 0.087 0.005 (LNHP), and 0.038 0.003 (LNLP)) (Figure 3B). Phosphate uptake prices below HP situations had been larger than those beneath LP situations Water 2021, 13, x FOR PEER Overview 7 of 12 (Figure 3B, HP:LP, F = 9.856, p = 0.004). In addition, phosphate uptake rates decreased to close to zero from day three in each of the scenarios (Figure 3B).1 Figure 3.

The QN in scenario was the highest through each of the stages, growing from day six to day 9 (p = 0.01), the HNLP scenario was the highest during all of the stages, growing from day six to day 9 whilst it remained unchanged inside the other scenarios (p = 0.06) (Figure 3C).
