Salt-alkalization may potentially promote Microcystis aeruginosa blooms and the production of microcystin-LR

Label-Free Chemiresistive Sensors Based on Self-Assembled Ti3C2Tx MXene Films for Monitoring of Microcystin-LR in Water Samples

“…aeruginosa. Yu et al found similar results. They observed that the threat of ionic toxicity and hypertonic shock in the saline environment led to organelle damage and metabolic dysfunction of M.…”

“…During the culture time from day 7 to the end of the experiment, the cell densities of M. aeruginosa under EC values of 2.5 and 5.0 mS cm −1 were smaller than that with EC values of 2.0 mS cm −1 (Figure S11A), indicating that an increase in salinity level inhibited the growth of M. aeruginosa. Yu et al 49 found similar results. They observed that the threat of ionic toxicity and hypertonic shock in the saline environment led to organelle damage and metabolic dysfunction of M. aeruginosa, thus affecting its growth and reproduction.…”

“…aeruginosa can release a large number of MCs during its growth. The growth process and the physiological activity of MC-LR release are influenced by environmental factors such as temperature, salt, etc . With this basis, we set up culture conditions with three different salinity levels to cultivate M.…”

“…The growth process and the physiological activity of MC-LR release are influenced by environmental factors such as temperature, salt, etc. 49 With this basis, we set up culture conditions with three different salinity levels to cultivate M. aeruginosa. The electrical conductivities (EC) corresponding to the three salinity levels were 2.0, 2.5, and 5.0 mS cm −1 , respectively.…”

“…50 At the same time, it is possible that salinity stress affected the expression of related proteins on the cell membrane surface of M. aeruginosa, which altered its transport pathway for MC-LR release into an aqueous environment. 49 The S and L methods were evaluated for consistency by Bland−Altman analysis. As shown in Figure 5D, all numerical points were within 95% agreement limits, with a maximum value of 1.07 and a minimum value of 0.96.…”
