Cyanobacteria and Bloom Control Management System

2020 IEEE International Conference on Artificial Intelligence and Computer Applications (ICAICA), 2020
Cyanobacteria are a large class of single-cell prokaryotes capable of oxygen-producing photosynthesis. When cyanobacteria are stimulated by nitrogen, phosphorus and other elements, it will cause eutrophication of the water body and cause the phenomenon of “bloom” in the lake, which seriously endangers the safety of humans, livestock, fish and shrimp ...

Cyanobacteria blooms in the Baltic Sea

2023
In the Baltic Sea, cyanobacteria regularly form massive blooms in late summer. These blooms can produce toxins and have the potential to counteract management efforts to limit eutrophication because they add bioavailable nitrogen (fixed from the atmosphere) to an already over-fertilized system.

Predicting cyanobacteria bloom occurrence in lakes and reservoirs before blooms occur

Science of The Total Environment, 2019
With increased global warming, cyanobacteria are blooming more frequently in lakes and reservoirs, severely damaging the health and stability of aquatic ecosystems and threatening drinking water safety and human health. There is an urgent demand for the effective prediction and prevention of cyanobacterial blooms.

Weather Variability, Sunspots, and the Blooms of Cyanobacteria

EcoHealth, 2009
The roles of weather variability and sunspots in the occurrence of cyanobacteria blooms, were investigated using cyanobacteria cell data collected from the Fred Haigh Dam, Queensland, Australia. Time series generalized linear model and classification and regression tree (CART) model were used in the analysis.

Pigment assemblages in subtropical bloom-forming cyanobacteria strains

Journal of Plankton Research, 2023
Abstract Pigments are powerful indicators for chemotaxonomy and remote sensing studies, which are the approaches used for cyanobacterial bloom monitoring. Cyanobacterial pigments include high concentrations of phycobilins and diverse carotenoids.

Cyanobacteria blooms: effects on aquatic ecosystems

2008
Cyanobacteria become increasingly dominant as concentrations of TP and TN increase during eutrophication of lakes, rivers and estuaries. Temporal dynamics of cyanobacteria blooms are variable--in some systems persistent blooms occur in summer to fall, whereas in other systems blooms are more sporadic.

Trophodynamics of Marine Cyanobacteria Blooms

1992
Although cyanobacteria blooms can dominate annual production and phytoplankton biomass in some marine regions, little is known on the fate of these large aggregations of autotrophic, surface-dwelling prokaryote populations. The importance of bloom-forming Trichodesmium spp.

Physiology, Blooms and Prediction of Planktonic Cyanobacteria

2012
This chapter addresses some of the challenges associated with trying to model population fluctuations, bloom formation and collapse of planktonic cyanobacteria. It is argued that improved modelling and prediction rely on a better understanding of the physiological responses of cyanobacteria to the physical and chemical characteristics of their ...

Zooplankton Grazing in a Potomac River Cyanobacteria Bloom

Estuaries, 1993
During summer, bloom-forming cyanobacteria, including Anacystis, Aphanizomenon, and Microcystis aeruginosa, dominate tidal-fresh waters of the upper Potomac River estuary with densities exceeding 108 cells l−1. In an attempt to determine the importance of these high cyanobacteria densities to planktonic herbivory in the system, short-term grazing ...

Kinetic Study on Pyrolysis of Blooming-forming Cyanobacteria

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2015
The pyrolysis kinetics of blooming-forming cyanobacteria was studied using thermogravimetric analysis at heating rates of 5–20°C/min. The pyrolysis process appeared in three stages: dehydration, primary devolatilization, and residual decomposition. With the increasing heating rate, the maximum rate of weight loss and the peak temperature increased. The
