“…The total content of phenolic compounds in M. spicatum can reach up to 12% (dry weight), and the content of algaecide telimagrandin II-up to 2% [72]. The influence of phenolcarboxylic acids on epiphytic algae has also been demonstrated [73,74]. In this case, gallic, salicylic, and caffeic acids show the highest allelopathic activity, changing the dominant epiphytic algae when the ecological state of water bodies changes.…”

“…A number of studies demonstrated an inhibitory effect of aquatic vascular plants on phytoplankton growth in a wide range of macrophyte areal cover (3-100%) [21,25,74,117]. The potential impact of allelopathy is particularly notable in water bodies with a high level of macrophyte coverage, 20% or more [21,24,118].…”

Intense “blooming” of cyanobacteria (blue-green algae) caused by eutrophication and climate change poses a serious threat to freshwater ecosystems and drinking water safety. Preventing the proliferation of cyanobacteria and reducing water nutrient load is a priority for the restoration of eutrophic water bodies. Aquatic plants play an important role in the function and structure of aquatic ecosystems, affecting the physiochemistry of the water and bottom sediments, primary production, and biotic interactions that support a balanced ecosystem. This review examines the inhibitory effect of aquatic vascular plants on harmful blooms of cyanobacteria. Aquatic plants are able to successfully inhibit the growth of cyanobacteria through various mechanisms, including by reducing nutrient and light availability, creating favorable conditions for the development of herbivorous zooplankton, and releasing allelopathic active substances (allelochemicals) with algicidal effect. Allelopathy is species-specific and therefore acts as one of the key mechanisms by which the development of cyanobacterial populations in aquatic ecosystems is regulated. However, allelopathic activity of aquatic vascular plants depends on various factors (species characteristics of aquatic plants, area, and density of overgrowth of water bodies, physiochemical properties of allelopathically active substances, hydrological and hydrochemical regimes, temperature, light intensity, etc.), which may regulate the impact of allelochemicals on algal communities. The paper also discusses some problematic aspects of using fast-growing species of aquatic vascular plants to control cyanobacterial blooms.

The composition and content of phenol carboxylic acids was studied in water bodies among higher aquatic plants of various ecological groups: emergent (Typha angustifolia L., Scirpus lacustris L., and Phragmites australis (Cav.) Trin. ex Steud.), submerged (Ceratophyllum demersum L. and Myriophyllum spicatum L.), and with floating leaves (Trapa natans L. and Nuphar lutea L.). The following acids were found in the water among higher aquatic plants: benzoic, lilac, vanillic, gallic, n-oxybenzoic, protocatechuic, α-resorcylic, β-resorcylic, salicylic, ferulic, caffeic, cinnamic, coumaric, and sinapic. Their total concentration in the water among the specimens of T. angustifolia accounted for 114.7 μg/L, Sc. lacustris - 24.71 μg/L, T. natans - 56.14 μg/L, N. lutea -19.3 μg/L, C. demersum -25.42-38.66 μg/L, and M. spicatum - 1.42-2.83 μg/L. The analysis of the content of phenol carboxylic acids in the water among the specimens of Ph. australis during the spring-autumn period revealed significant differences both in the ratio of individual acids and in their distribution by groups. The maximal concentration of benzoic and salicylic acids in the water was registered at the beginning of Ph. australis development, whereas the maximal content of vanillic and gallic acids - during plant active vegetation. The lowest content of cinnamic and ferulic acids was recorded at the beginning of vegetation season. Cluster analysis of the content of phenol carboxylic acids in the water among the specimens of C. demersum and M. spicatum at two sampling stations (Sobache Gyrlo Bay and Verblyud Bay in the Kaniv Reservoir) made it possible to reveal two groups of the studied substances. The first group included benzoic and gallic acids and the second group - other acids. The use of the principal component analysis (PCA) made it possible to establish a significant correlation between the composition and content of phenol carboxylic acids in the water among higher aquatic plants and dominant plant species. This fact is indicative of the leading role of higher aquatic plants in the formation of the pool of these substances in the water.

It has been found that the addition of phenol carboxylic acids and bio-flavonoids (50-200 μg/L) to the nutrient medium of algae during their cultivation resulted in the increase in the biomass of green microalgae Selenastrum gracile, Monoraphidium griffithii, and Acutodesmus acuminatus by a factor of 1.2-3.5 depending on the stage of culture growth and active substance. The most significant influence on the specific growth rate of green microalgae cultures was exerted by salicylic and gallic acids, selectively by oxycinnamic acids and bioflavonoids. The obtained data deserve attention in further research aimed at obtaining algal biomass with an increased content of biologically valuable compounds (proteins, carbohydrates, lipids, etc.) in cultivating in biotechnological complexes.
