Effect of Potamogeton pusillus on Water Quality and Plankton CommunityEffect of Potamogeton pusillus on Water Quality and Plankton Community
In closed aquatic environments like ponds or lakes, water bloom caused by eutrophication has severely damaged aquatic ecosystems. Some previous studies suggested that submerged macrophytes contribute to the development of aquatic ecosystems and water purification. Although water purification and lake ecosystem restoration using submerged macrophytes have been greatly studied, their specific mec...
متن کاملDifferent Sensitivities of Selenastrum capricornutum and Toxic Strain Microcystis aeruginosa to Exudates from Two Potamogeton Species
The sensitivities of Selenastrum capricornutum and the toxic strain Microcystis aeruginosa to exudates from Potamogeton maackianus and P. malaianus were compared using exudation experiment, and the potential allelochemicals released by these two pondweeds into surrounding water were also analyzed. The growth of S. capricornutum and M. aeruginosa was inhibited by the exudates from the two macrop...
متن کاملPhenolic Compounds Exuded from Two Submerged Freshwater Macrophytes and Their Allelopathic Effects on Microcystis aeruginosa
Culture solutions of the submerged freshwater macrophytes Hydrilla verticillata and Vallisneria spiralis, separately incubated at 10 g of fresh weight (FW) per liter for three days, were extracted by solid phase extraction (SPE) followed by liquid liquid extraction (LLE), and the acquired ethyl acetate fractions were analyzed by gas chromatograph-mass spectrometry (GC-MS) to identify potential ...
متن کاملDoes Microcystis aeruginosa have quorum sensing?
Quorum sensing (QS) is a system of cell-to-cell communication by means of intercellular signaling molecules to coordinate a set of targeted gene expression or repression in many Gram-negative bacteria; it plays important roles for bacteria in adaptation to adverse environmental conditions. In this study, we first demonstrated that Microcystis aeruginosa PCC-7820 could produce QS-related signal ...
متن کاملInhibitory effects of sanguinarine against the cyanobacterium Microcystis aeruginosa NIES-843 and possible mechanisms of action.
Sanguinarine showed strong inhibitory effect against Microcystis aeruginosa, a typical water bloom-forming and microcystins-producing cyanobacterium. The EC50 of sanguinarine against the growth of M. aeruginosa NIES-843 was 34.54±1.17 μg/L. Results of chlorophyll fluorescence transient analysis indicated that all the electron donating side, accepting side, and the reaction center of the Photosy...
