“…and Microcystis aeruginosa (Leu et al, 2002;Zhu et al, 2010). Oxidative damage, including loss of membrane integrity and inhibition of protein synthesis, is also an important mechanism of toxicity of plant allelochemicals against M. aeruginosa (Lu et al, 2016;Tazart et al, 2020). However, allelopathic products can simultaneously stimulate a significant increase in the activity of antioxidant enzymes, e.g., superoxide dismutase and catalase, suggesting their involvement in the elimination of oxidative stress in cyanobacteria (Hong et al, 2008;Lu et al, 2016;Zhang 2015;Hua et al, 2018;Kang et al, 2020;Tazart et al, 2020).…”

Additionally, various phenolic compounds, fatty acids, terpenoids and asarone synthesized by aquatic plants reduce the biomass of cyanobacteria and induce changes in their cell and colonial morphology (Nakai et al, 2000;Rojo et al, 2013;Hang, 2017;Mowe et al, 2019;Tazart et al, 2019).…”

Inhibition of growth rate and cylindrospermopsin synthesis by Raphidiopsis raciborskii upon exposure to macrophyte Lemna trisulca (L)

Impact of macrophyte Lemna trisulca on the growth rate and synthesis of cylindrospermopsin (CYN) by cyanobacterium Raphidiopsis raciborskii was determined. The presence of L. trisulca inhibited the biomass accumulation of the cyanobacterium by 25% compared to the control during co-cultivation. The simultaneous cultivation of these organisms slightly affected the inhibition of macrophyte growth rate by 5.5% compared to the control. However, no morphological changes of L. trisulca after incubation with cyanobacteria were observed. It was also shown that the long-term (35 days) co-cultivation of R. raciborskii and L. trisulca led to a decrease in CYN concentration in media and cyanobacterial cells by 32 and 38%, respectively, compared to the values obtained for independent cultivation of cyanobacterium. Excessive absorption of phosphate ions by L. trisulca from the medium compared to nitrate ions led to a significant increase in the nitrate:phosphate ratio in the media, which inhibits the development of cyanobacterium. The obtained results indicate that L. trisulca in the natural environment may affect the physiology of cyanobacteria. The presented study is the first assessment of the allelopathic interaction of macrophyte and R. raciborskii.

“…There is no doubt that allelochemicals affect the biological and biochemical characteristics of algae, and artemisinin is no exception. Most researchers have talked about the influence of allelochemicals on photosynthetic system (Xing et al 2018, Zhu et al 2010, cell membrane (Shao et al 2009) and enzyme activity (Lu et al 2016) when studying the inhibitory mechanism of allelochemicals. The inhibitory mechanism of artemisinin's consistency with the inhibitory mechanism of other allelochemicals still needs to be further explored.…”

Environment-friendly algaecides based on allelopathy have been widely used to control harmful algal blooms. In this research, micro nano scale artemisinin sustained-release algal inhibitor was prepared, the optimal preparation conditions were explored and the inhibitory mechanism of artemisinin algaecides was perfected. The results showed that when the particle size of artemisinin sustained-release microspheres (ASMs) was 2/10000 of artemisinin sustained-release granules (ASGs), the inhibitory effect was more remarkable. The optimal concentration of ASMs was 0.2 g L-1, and the inhibitory effect reached 99% on the 10th day; The algae density and chlorophyll-a both showed a downward trend, indicating that ASGs and ASMs could promote the degradation of chlorophyll-a; The inhibition rate of ASGs was faster than that of ASMs on the 4th day, and the inhibitory effect of ASMs was more significant after the 5th day. The activities of superoxide dismutase (SOD), peroxidase (POD), catalase (CAT) increased rapidly at first and then decreased, which indicated that ASGs and ASMs caused oxidative damage to Microcystis aeruginosa (M. aeruginosa) and inhibited the activity of antioxidant enzymes. Furthermore, the content of the oxygen free radical (O2-) and malondialdehyde (MDA) continued to rise after the 5th day, the protein, nucleic acid and conductivity in the culture medium increased. These results showed that lipid peroxidation occurred in the algal cell membrane, and the permeability of the membrane increased. In summary, the ASMs had significant continuous inhibitory effect while the ASGs had better short-term effect. The main inhibitory mechanism of artemisinin algaecides is the irreversible damage of cell membrane.

“…Furthermore, allelochemical compounds extracted from several macrophytes demonstrated dose‐dependent trends on both physiological (chlorophyll content, lipid peroxidation and protein content) and antioxidant parameters (Superoxide dismutase, SOD; Peroxidase, POD; and Catalase, CAT (Zhang et al ., 2015; Wang et al ., 2015a; Li et al ., 2016; Chen et al ., 2017; Jiang et al 2019). Pyrogallic acid extracted from Myriophyllum spicatum caused inhibition of protein synthesis and increasing malondialdehyde (MDA) levels, which are commonly used as important indicators in evaluating the growth conditions of cells and the mechanism of cells apoptosis (Lu et al ., 2014, 2016; Tang et al ., 2015; Chen et al ., 2017; Xie et al ., 2019). On the contrary, the activities of antioxidant enzymes play an important role in the metabolism and balance of free radicals of the organism (Suzuki and Mittler, 2006).…”

CAT, POD and SOD activities were significantly increased in M. aeruginosa cells under different concentrations of several compounds, such as glufosinate (Zhang et al ., 2017), pyrogallic acid (Lu et al ., 2016) or under different types of extracts, such as crude extracts of Sagittaria trifolia (Li et al ., 2016) and aqueous extracts of rice straw Oryza sativa (Hua et al ., 2018).…”

Macrophytes are a promising source of bioactive compounds with potential applications in the biocontrol of harmful cyanobacteria blooms. In this study, we investigated the inhibitory effects of extracts from three macrophytes (Nasturtium officinale, Potamogeton natans and Ranunculus aquatilis) on Microcystis aeruginosa. We assessed physiological indicators of inhibition on M. aeruginosa, including lipid peroxidation, protein content, superoxide dismutase activity, catalase activity and growth. The chemical composition of the macrophyte extracts and their specific allelochemicals were analysed using high‐performance liquid chromatography (HPLC). Results showed that M. aeruginosa growth was significantly inhibited after 8 days of exposure, with inhibitory rate varying from 96.98% to 99.01%. The macrophyte extracts caused cyanobacterial cell membrane and antioxidant defence system damage. Thirteen different compounds were identified as allelochemical compounds that could be responsible for M. aeruginosa growth inhibition and oxidative stress. Our findings suggest that allelopathic compounds from macrophytes may be used to effectively control cyanobacteria blooms and promote the restoration of aquatic ecosystems.
