Different sensitivities of Selenastrum capricornutum and toxic strain Microcystis aeruginosa to exudates from two potamogeton species was written by Zhang, Sheng-hua;Sun, Pei-shi;Ge, Fang-jie;Wu, Zhen-bin. And the article was included in Polish Journal of Environmental Studies in 2011.Product Details of 20324-33-8 This article mentions the following:
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 allelochems. 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 macrophytes. Compared to the control, the cell densities of S. capricornutum decreased by 42.7% and 61.9% in 2.5 and 5 g·L-1 FW P. maackianus treatments, and the cell densities of S. capricornutum also decreased by 65.8% and 73.5% in the two biomass d. treatments of P. malaianus after three days of treatments. After 3 days’ incubation in 2.5 and 5 g FW·L-1 P. maackianus exudates, the M. aeruginosa cell densities were higher in control than in treatment. As for P. malaianus treatments, the cell densities of M. aeruginosa were reduced by 16.5 and 65.8% of the control in 2.5 and 5 g·L-1 FW marophytes at the end of incubation period, resp. The allelochems. exuded from the macrophytes, which inhibited both S. capricornutum and M. aeruginosa, belonged to lipophilic and moderately lipophilic compounds according to the bioassay results of exudate fractionations. By multiple comparison statistics, the results showed that P. maackianus had stronger inhibitory effects on M. aeruginosa, while S. capricornutum was more sensitive to the allelochems. of P. malaianus. The different sensitivities of the two algae were probably caused by three alc. compounds (1-methoxy-2-methyl-2-Propanol, 2-methyl-2-Hexanol, and 4-ethyl-2,6-dimethyl-4-Heptanol) through the GC-MS anal. of the most active exudate fractions. In the experiment, the researchers used many compounds, for example, 1-((1-((1-Methoxypropan-2-yl)oxy)propan-2-yl)oxy)propan-2-ol (cas: 20324-33-8Product Details of 20324-33-8).
1-((1-((1-Methoxypropan-2-yl)oxy)propan-2-yl)oxy)propan-2-ol (cas: 20324-33-8) belongs to ethers. The oxygen atom in ethers are more electronegative than carbon, thus the hydrogens which are alpha to the ethers are more acidic than the simple hydrocarbons. At room temperature, ethers are pleasant-smelling colourless liquids. Relative to alcohols, ethers are generally less dense, are less soluble in water, and have lower boiling points. They are relatively unreactive, and as a result they are useful as solvents for fats, oils, waxes, perfumes, resins, dyes, gums, and hydrocarbons. Vapours of certain ethers are used as insecticides, miticides, and fumigants for soil.Product Details of 20324-33-8
