Elucidating the Effect of Fluid Field on Cyanobacterial Colony Formation: Focusing on Carbon Dioxide and Bound Extracellular Polymeric Substances

Опубликована: Янв. 1, 2024

Biomass and fluid field were two basic conditions for cyanobacterial bloom formation, which have been reported in many studies. However, the mechanism of biomass enrichment colony formation affected by was unclear. In this study, optimal determined via monitoring artificial simulation. Furthermore, cultivation macroscopic spherical colonies laboratory achieved L-wave group (wind speed 3 m s-1, flow rate 0.008 s-1 wave height 0.03 m), can be attributed to faster CO2 transmission more bound extracellular polymeric substances (bEPS) secretion. high shear force H-wave 0.10 m) inhibited growth destructing cell membrane. Anti-oxidant enzyme activities gene expressions related oxidation system, photosynthesis, EPS synthesis gas vesicle supported these results as well. Additionally, thresholds 6.43 mg L-1 CO2, 8.40 pg cells-1 bEPS, boundary stress (1.13×10-4 Pa) (0.004~0.008 s-1) fitting relevant parameters. Overall, study provided deeper insights into effect on algal a novel strategy predicting blooms.
