Microcystis - an overview | ScienceDirect Topics
Microcystis is a cosmopolitan freshwater cyanobacterium known for forming toxic blooms in eutrophic water bodies [144]. It is characterized by spherical cells grouped into colonies with or without mucilage.
Microcystis - an overview | ScienceDirect Topics
Microcystis has a colony formation feature, which is one of the major characteristics to be a dominant species in eutrophic waters. As previously discussed, Microcystis colony mainly consists of Microcystis, associated microorganisms, and EPS.

6 Biofunctions of microcystins in Microcystis. The question, what are the biofunctions of microcystins in Microcystis, remains an open one. In the past few decades, various hypotheses (related to cell-to-cell communication [96], fitness improvement [97,98], colony formation [99], etc.) in Microcystis have been proposed and widely discussed [100 ...

2021年5月1日 · The harmful algae in cyanobacterial blooms mainly consist of Microcystis sp., Anabaena sp., Cylindrospermopsis sp., Aphanizomenon sp., and Oscillatoria sp. Among them, Microcystis aeruginosa is a particularly dominant harmful cyanobacterial species [11, 12] and blooms of this species cause cyanobacterial toxins to accumulate. With improvements ...

2023年6月20日 · Systematic reviews summarizing the relationship between Microcystis and P in aquatic environments are scarce. . Therefore, this study aimed to compile recent findings on the interactions between Microcystis spp. and P to provide a comprehensive understanding of eutrophication and cyanobacterial blooms and elucidated their relationship with aquatic environme
Mechanisms of harmful effects of Microcystis aeruginosa on a …
2024年3月1日 · Microcystis aeruginosa is typically the dominant species in cyanobacterial blooms, adversely affecting the growth of planktonic animals through toxin secretion and nutrient predation. In chronic toxicity experiments, it was found that under the stress of microcystis, both the survival and reproduction of the M. mongolica were severely inhibited.
