Growth inhibition and oxidative damage of Microcystis aeruginosa induced by crude extract of Sagittaria trifolia tubers

Assessment of the Potentially Algicidal Effects of Thymus Satureioides Coss. And Artemisia Herba Alba L. Against Microcystis Aeruginosa

“…These observations are in agreement with previous studies that investigated the cell morphology variations under treatments (Meng et al, 2015;Li et al, 2016). In our study, the photosynthetic pigments of M. aeruginosa were destroyed by aqueous extracts.…”

“…On the other hand, T. saturoides at a concentration of 0.5% was sufficient to elicit a strong inhibition on the growth of M. aeruginosa. The difference between the present results and that of Nakai et al (1999) might be explained by the importance of aerobic decomposition to generate more inhibitors for algal suppression (Li et al, 2016). Tebaa For A. herba alba, only the concentration of 1% was significantly inhibitory compared to the controls, which suggests that the potentially bioactive substances inhibited the growth of M. aeruginosa.…”

“…The aqueous extraction of plants was carried out according to the method described by Ball et al (2001), slightly modified by Li et al (2016). Briefly, 10g of leaves were cut into tiny pieces and placed in 100 ml distilled water under agitation (37°C; 48 h).…”

“…Recent researches have exploited plants as an alternative to chemical agents Zhou et al, 2014;Meng et al, 2015;Li et al, 2016). Numerous studies have reported the inhibition of cyanobacterial biomasses by several aquatic plants such as Potamogeton maackianus (Wu et al, 2007), Myriophyllum spicatum (Zhu et al, 2010), Sagittariatrifolia (Li et al, 2016), and Eichhornia crassipes (Zhou et al, 2014).…”

To explore the potential of terrestrial plant extracts for controlling cyanobacteria provide a new guide for developing algicide (Shao et al, 2013 (Wang et al, 2015).…”
