The cyanobacterium species Microcystis aeruginosa produces microcystin and an array of diverse metabolites believed responsible for their toxicity and/or immunogenicity. The seasonal variation of Microcystis colonial morphology in Lake Taihu was investigated from June 2011 to November 2011 and found that M. ichthyoblabe, M. wesenbergii and M. aeruginosa successively dominated in Lake Taihu. Microcystis colony formation facilitates the maintenance of high biomass for a long time, and the growth of heterotrophic bacteria was enhanced by EPS secretion from M. aeruginosa. The colonies were collected in Lake Taihu, kept under 25°C on a 12h:12h light/dark cycle at a light density of about 45 µmol m–2s–1. during flagellate grazing, cultures of M. aeruginosa were exposed to grazing Ochromonas sp. Microcystis aeruginosa was cultured in the medium containing low and high concentrations [10% and 65% (v/v)] of black and white ash water extracts (BE and WE) to study dynamic changes of carbonaceous, nitrogenous, and oxygenated DBP precursors during algal growth. Previously, chronic rhinitis patients were demonstrated to elicit a specific IgE response to nontoxic strains of M. aeruginosa … To investigate the changes in the morphology and polysaccharide content of Microcystis aeruginosa (Kütz.) In this paper, M. aeruginosa responded actively to flagellate … 27 with Microcystis aeruginosa naturally as well as those cultured under defined media and their 28 possible effects on the morphology and growth properties of the cyanobacterium. for a period of 9 d under controlled laboratory conditions. Thus, it is necessary to study cyanobacteria blooms and explore the growth of Microcystis aeruginosa under di erent nutrient conditions. The draft genomic sequences of Microcystis aeruginosa NIES-3787, NIES-3804, NIES-3806, and NIES-3807 have been deposited in DDBJ/EMBL/GenBank under the accession numbers BJCH01000001 to … Background . Abstract: Microcystis aeruginosa is the dominant alga forming cyanobacteria blooms, the growth of which is limited by available nutrients. Intraspecific Variation in Growth and Morphology of the Bloom-Forming Cyanobacterium Microcystis aeruginosa Alan E. Wilson, 1* Whitney A. Wilson,2 and Mark E. Hay Georgia Institute of Technology, School of Biology, 310 Ferst Drive, Atlanta, Georgia 30332,1 and Columbia University, Lerner Box 2516, New York, … Bacterial associations are known to alter microenvironment of Microcystis and potentially influence their … Microcystis is a genus of freshwater cyanobacteria that includes the harmful algal bloom-forming Microcystis aeruginosa.Many members of a Microcystis community can produce neurotoxins and hepatotoxins, such as microcystin and cyanopeptolin.Communities are often a mix of toxin-producing and nonproducing … Our results … Kütz.

We investigated the changes in the morphology, genetics and photosynthetic characteristics of Microcystis aeruginosa colonies during two months of cultivation. The results from our study suggest that natural heterotrophic bacterial communities have a role in the development of Microcystis … M. 29 aeruginosa (UPMC-A0051) was isolated during a bloom from Putrajaya Lake, Malaysia and often pose severe problems to the environment and general community due to their persistent presence in eutrophic water bodies and potential to form blooms. The morphological and physiological characteristics of M. aeruginosa and changes of het-erotrophic bacterial community composition were investigated in the course of coculture of M. aerugin-osa and heterotrophic bacterial community.
