“…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.…”

“…Some allelochemicals act by inhibiting photosynthesis, slowing down the growth of M. aeruginosa. They also attack the reactive oxygen species (ROS) on cell membranes by degrading unsaturated phospholipids and consequently increasing their permeability, leading to a disorder in cell organization (Meng et al, 2015).…”

Abstract. In search of an ecofriendly algaecide, aqueous extracts of two medicinal plants, Thymus satureioides Coss. and Artemisia herba alba L., were assessed for antialgal activity against Microcystis aeruginosa. An experiment was designed using five treatments (1%, 0.75%, 0.5%,0.25% and 0.1%). The growth of M. aeruginosa, morphological modifications, and photosynthetic pigments (chlorophyll a and carotenoids) on exposure to the extracts were explored. Also, phytochemical parameters in the extracts were analyzed to reveal the potential allelochemical compounds.The results showed that both T. satureioides and A. herba alba extracts inhibited the growth of M. aeruginosa in a concentration-dependent way. After 8 days of treatment, the highest inhibition rates reached were 95%, 93% and 88.58%, and for T. satureioides and A. herba alba aqueous extracts, respectively. Chlorophyll a and carotenoid concentrations in cultures decreased especially in the 1% treatment group. Several morphological changes were observed in the treatment group compared to the controls. It was concluded that M. aeruginosa growth was suppressed by the potentially allelochemical compounds and probably by other allelochemical substances in aqueous extracts. Our results illustrated that both T. satureioides and A. herba alba extracts are able to control Microcystis blooms, and these may be recommended as a remedy for contamination of water bodies by harmful blooms.

“…In addition, it is easy to be harvested and removed from water due to its large algae plant [14]. Meanwhile, Microcystis was mainly selected in the studies on allelopathy [27,32,[35][36][37][38], but as another main algal specie inducing blooms [35,39], Chlorella was rarely chosen. Chlorella grows in freshwater lakes and ponds, and generally begins to grow and multiply when the water temperature is stable and higher than 20 • C. It has very strong abilities of photosynthesis and reproduction in summer, thus often forming blooms.…”

“…Studies have shown that many kinds of aquatic plants have the ability to resist and control eutrophication, such as reed, Ceratophyllum demersum, Ruppia [4,[23][24][25]. Due to the advantages of high efficiency, low cost, and no secondary pollution, the method of algae control by plant allelopathy is of great significance for preventing and repairing water bodies from eutrophication [24,[26][27][28], and maintaining water stability after restoration.…”

Eutrophication has become increasingly serious in recent years, which severely impairs the aquatic ecosystem. Applying environmentally-friendly methods to effectively control the growth of algae and avoid eutrophication has been proved to be a promising way. Thus, the potential of Hydrodictyon reticulatum on eutrophication control was studied in this research. The allelopathy inhibitory effects of H. reticulatum on the growth of Chlorella pyrenoidosa were investigated under both co-culture and liquor-cultured conditions. The biomass and chlorophyll a content of C. pyrenoidosa were determined with time during the experimental period. Nitrogen and phosphorus removal capacities of H. reticulatum were also examined. Results showed that the growth of C. pyrenoidosa was obviously inhibited under both co-culture and liquor-cultured conditions, and the "Hormesis effect" was patently observed. The strength of allelopathy inhibitory effect depended on the relative biomass between H. reticulatum and C. pyrenoidosa. The allelopathy inhibitory effect of H. reticulatum on C. pyrenoidosa under co-culture condition was stronger than that under liquor-cultured condition. The decrease speeds of nitrogen and phosphorus concentrations were in direct proportion to the concentration of H. reticulatum.
