Chemical analysis of the phenol-water-extractable materials from Anabaena flos-aquae.
The high molecular-weight carbohydrate substances extracted in the aqueous and phenol phases by phenol-water extraction of Anabaena flos-aquae A-37 were found to be polysaccharides without lipid attached.
متن کاملToxicology and pharmacological action of anabaena flos-aquae toxin.
Calves, rats, ducks, and goldfish given lethal oral doses of bacteria-free lyophilized cell suspensions of toxic Anabaena flos-aquae died as a result of respiratory arrest. Experiments with selected animals and pharmacological preparations showed that the main effect of the toxin was production of a sustained postsynaptic depolarizing neuromuscular blockade.
متن کاملToxicity of Seven Herbicides to the Three Cyanobacteria Anabaena flos-aquae, Microcystis flos-aquae and Mirocystis aeruginosa
The toxicity of 7 herbicides to the three cyanobacteria was tested in this work. The results indicated that: (1) There was a highly significant relationship between dried weight or chlorophyll-a and OD680nm for tested cyanobacteria; (2) the toxicity of the tested herbicides with the order from high to low was: photosynthesis-inhibiting > ACCase inhibitor > protox inhibiting herbicides; (3) the ...
متن کاملInterspecific competition between Microcystis aeruginosa and Anabaena flos-aquae from Taihu Lake, China.
Microcystis and Anabaena are the main cyanobacteria that cause cyanobacterial blooms in Taihu Lake, China. The mechanism of population competition between M. aeruginosa and A. flos-aquae was studied by co-cultivation in the laboratory. The growth of M. aeruginosa was inhibited, while the growth of A. flos-aquae was promoted. The degree of inhibition or promotion was related to the ratio of the ...
متن کاملDetermination of Cu environments in the cyanobacterium Anabaena flos-aquae by X-ray absorption spectroscopy.
Whole cells and peptidoglycan isolated from cell walls of the cyanobacterium Anabaena flos-aquae were lyophilized and used at pH 2 and pH 5 in Cu(II) binding studies. X-ray absorption spectra measured at the Cu K-edge were used to determine the oxidation states and chemical environments of Cu species in the whole-cell and peptidoglycan samples. In the whole-cell samples, most of the Cu retained...
