“…What's more, as the reason of vulnerable influenced by temperature and light intensity, the removal rate of other reported bioremediation methods could easily been affected, such as the aquatic plant and macrophytic algae restoration system (Zuo et al 2014;Xu et al 2011) and the Ipomoea aquatica with low-energy ion implantation method (Li et al 2009). However, the removal rate of the designed bioreactor were little influenced when the bioreactor was running, especially for TP, TN and Chl-a, which the removal rates were approximately or greater than 90%.…”

To investigate the purification effect of the new adsorption material containing bioreactor and the critical role of non-culture (VBNC) bacteria in eutrophication ecosystem, major water quality parameters and microbial community were determined and analyzed in prepared eutrophic water for 2 years monitoring. The results showed that removal rates of total phosphorus (TP), total nitrogen (TN), chlorophyll-a (Chl-a) and chemical oxygen demand (COD) ranged of 90.7% -95.9%, 84.5% -92.4%, 87.9% -95.8% and 68.3% -82.7%, respectively, indicating the designed bioreactor possessed high efficiency in eutrophic water treatment. Although the bioreactor had been operated for 2 years, water from treatment group was more clearer and odorless than control group, exhibiting the long service life of the bioreactor. Stopping operation in August caused the removal rates of major water quality parameters significantly decrease (p < 0.05), revealing stopping operation and high temperature in Summer exerted dual effect on the bioreactor, whereas the impact could be minimized when the bioreactor was running. According to most probable number (MPN) method, the total bacteria under +Rpf treatment were higher than under -Rpf treatment, implying Rpf could resuscitate VBNC bacteria in eutrophication ecosystem. Nine VBNC bacteria were isolated based on the BLAST results of 16S rRNA gene, and these bacteria might contribute to eutrophic water treatment based on their functions, such as phosphorus-collecting and denitrification. Those results provided new insights for engineering technology innovation and had benefit in eutrophic water treatment.

“…, Posidonia oceanica [ 5 ], Nelumbo nucifera [ 6 ], Azolla microphylla [ 7 ], and Eichharnia crassipes [ 8 ]. Usually the content of flavonoids in aquatic plants ranged from 0.005% to 1.2% of the plant dry mass [ 6 , 9 , 10 , 11 ]. Flavonoids are released into the environment by growing plants especially when they are under physiological stress, or from decomposing parts of plants.…”

Flavonoids are natural polyphenolic compounds produced by many aquatic plants and released in their environments. In this study, the effects of several aquatic flavonoids on cyanobacterial Microcystis aeruginosa, especially in relation to the cell growth, photosynthetic activity, cell morphology, and cell membrane integrity, were investigated. Significant growth inhibition was observed when the cyanobacteria were exposed to three flavonoids, namely, 5,4'-dihydroxyflavone (DHF), apigenin, and luteolin. Luteolin reduced the effective quantum yield, photosynthetic efficiency, and maximal electron transport rate by 70%, 59% and 44%, respectively, whereas 5,4'-DHF and apigenin slightly affected these parameters, which implies that luteolin disrupts the photosynthetic system. Moreover, 5,4'-DHF and apigenin compromised the membrane integrity, and induced membrane depolarization in 52% and 38%, and permeabilization in 30% and 44% of the cells, respectively. The 5,4'-DHF and apigenin showed more pronounced effects on M. aeruginosa morphology and membrane integrity, compared to the luteolin. These results suggest that flavonoids could have significant effects on growth and physiological functions in cyanobacterial species.
