Theoretical Analysis of the Potential of Silver Carp Hypophthalmichthys Molitrix in the Control of Water Blooming by Different Species of Cyanobacteria [PDF]

Журнал Сибирского федерального университета: Серия Биология, 2009
The possibility to use silver carp (Hypophthalmichthys molitrix) in the control of water blooming by cyanobacteria is theoretically analyzed. To attain this goal the dynamic model has been developed, describing communities of two species of cyanobacteria:

Fates of Microcystis aeruginosa Cells and Associated Microcystins in Sediment and the Effect of Coagulation Process on Them

Toxins, 2013
During toxic Microcystis aeruginosa blooms, large amounts of cells can enter sediment through natural settlement, and coagulation treatment used to control water blooms can enhance the accumulation of cells.

Phytotoxic Effects of Ethanolic Extracts of Magonia pubescens A.St.‐Hil. (Sapindaceae) on the Germination of Emilia sonchifolia (L.) DC. Seeds

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Ethanolic extracts from Magonia pubescens exhibit concentration‐dependent allelopathic activity against Emilia sonchifolia. Leaf extracts strongly inhibit seed germination and seedling growth, surpassing glyphosate under the tested conditions, whereas intermediate concentrations stimulate germination, indicating hormesis.

Antioxidant enzyme activities of Microcystis aeruginosa in response to nonylphenols and degradation of nonylphenols by M-aeruginosa [PDF]

, 2007
The aim of this study was to examine the effects of chemical nonylphenols (NPs) on the antioxidant system of Microcystis aeruginosa strains. The degradation and sorption of NPs by M. aeruginosa were also evaluated.

Occurrence of Microcystis aeruginosa and microcystins in Río de la Plata river (Argentina)

Acta Toxicológica Argentina, 2007
This paper is the first report on microcystins producer blooms of Microcystis aeruginosa in the Argentinean coast of the Río de la Plata river, the most important drinking water supply of Argentina. The distribution of toxic cyanobacterium Microcystis cf.

Impact of the invasive diatom species Cymbella janischii on riverine microbial biofilm communities and a potential role of bacterially produced zeatin

Journal of Phycology, Volume 62, Issue 4, Page 1221-1239, August 2026.
Abstract The diatom Cymbella janischii is an invasive species in Japan, causing nuisance blooms by forming thick mats in rivers. To date, there are no documented studies on the microbiome associations in C. janischii mats or the processes that drive bloom formation.

Effect of Microcystis Aeruginosa and duckweed combined growth on the purification of waste water

四川大学学报. 自然科学版, 2018
In this experiment, 0, 20, 40, 60, 80 and 100 mL/L of Microcystis aeruginosa(FACHB 930, 107 cells/mL) were cocultured with Spirodela punctata(ZH0051, 400 g/m2) in Hoagland which was diluted five times. Experimental results showed that the growth rate and

Nutrient disturbance in a shallow aquaculture pond impacts Microcystis gene expression but does not impact bacterial community function during bloom conditions

Journal of Phycology, Volume 62, Issue 4, Page 1297-1310, August 2026.
Abstract Cyanobacterial harmful algal blooms (cHABs) are worldwide issues. Reduced nitrogen forms (ammonium and urea) have recently been measured in freshwater systems at concentrations not previously recorded. These reduced nitrogen forms have been shown to favor the proliferation of harmful cyanobacteria.

Grazing on toxic and non-toxic Microcystis aeruginosa PCC7820 by Unio douglasiae and Corbicula fluminea

, 2009
To explore the potential grazing effects of mussels on Microcystis aeruginosa, a common bloom-forming phytoplankton, Unio douglasiae and Corbicula fluminea were fed with Scenedesmus obliquus, toxic and non-toxic strains of Microcystis aeruginosa as ...

Optimizing a long‐term monitoring strategy to track emerging cyanobacterial blooms in a Great Lakes estuary

Journal of Phycology, Volume 62, Issue 4, Page 1264-1296, August 2026.
Abstract Cyanobacterial harmful algal blooms (cHABs) are increasingly frequent and severe globally. Recently, the St. Louis River Estuary (SLRE) has experienced numerous cHABs, but the locations, timing, and environmental conditions associated with them are unknown.
