The toxic strain Microcystis aeruginosa (FACHB‐905) was purchased from Freshwater Algae Culture Collection of the Institute of Hydrobiology (FACHB, Wuhan, China) and was cultured for 4 weeks to establish standard curves between cell numbers and concentrations of 16S rDNA and mcyA genes determined by qPCR. The production of microcystins (MC) from Microcystis aeruginosa UTEX 2388 was investigated in a P-limited continuous culture. emend. A Gram-stain-negative, yellow-pigmented, strictly aerobic bacterium, designated strain MaA-Y11T, was isolated from a culture of Microcystis aeruginosa in the Republic of Korea. The cyanobacterium Microcystis aeruginosa is known to proliferate in freshwater ecosystems and to produce microcystins. Kim, M., Shin, B., Lee, J. et al. The Microcystis aeruginosa strain cultured in the lab showed a microcystin pattern similar to the field sample of 1999. 2015-07-17 08:47:44 Birger Skjelbred - Updated media metadata for Microcystis aeruginosa_1.jpg 2015-07-17 08:45:22 Birger Skjelbred - Added media: Microcystis aeruginosa_1.jpg Nordic Microalgae is developed and operated by the Swedish Meterological and Hydrological Institute (SMHI) with funding from the Swedish LifeWatch project . A series of cyanobacterial assays using pure culture solutions and extracts of culture solutions of C. alternifolius and C. generalis demonstrated allelopathic growth inhibition of a cyanobacterium M. aeruginosa. A unialgal culture of Microcystis aeruginosa Kütz. MC (MC-LR, MC-RR, and MC-YR) from lyophilized M. aeruginosa were extracted with 5% acetic acid, purified by a Sep-Pak C 18 cartridge, and then analyzed by high-performance liquid chromatography with a UV detector and Nucleosil C 18 reverse-phase column. Leucine incorporation by Microcystis aeruginosa Abstract—In experiments with axenic cultures of Microcys-tis aeruginosa, we tested whether this cyanobacterium incor-porates leucine, a compound that is often used for the mea- surement of heterotrophic bacterioplankton production. Cultures were cloned from a sample containing Microcystis aeruginosa, M. flos‐aquae and a few morphological intermediates. Confocal and scanning electron microscopic observations have previously shown the strong bacterial association of Microcystis aeruginosa cells on their surfaces. Morphological changes of Microcystis aeruginosa colonies in culture Qianqian SUN , 1 Wei ZHU, 1 ,2, Ming LI, 1 ,3,4 * Xiao TAN 1 1 College of Environment, Hohai University, No. In this study, M. aeruginosa was cultured in a chemostat to produce a culture in a steady state and clarify the toxin production relative to the growth of M. aeruginosa and its nutrient status (with a specific focus on P limitation), both of which seem to be important in eutrophic water. Microcystis aeruginosa UTEX 2388 was obtained from the Culture Collection of Algae at the University of Texas at Austin, USA. In this study, M. aeruginosa was cultured in a chemostat to produce a culture in a steady state and clarify the toxin production relative to the growth of M. aeruginosa and its nutrient status (with a specific focus on P limitation), both of which seem to be important in eutrophic water. Cells were non-motile rods showing catalase- and oxidase-positive reactions. … It produces a complex of symptoms similar to those which have been described for a number of toxic waterblooms. A continuous culturing system (chemostat) made of metal-free materials was successfully developed and used to maintain Fe-limited cultures of Microcystis aeruginosa PCC7806 at nanomolar iron (Fe) concentrations (20 to 50 nM total Fe).
