Freshwater lakes are threatened by harmful cyanobacterial blooms, whose basic unit is Cyanobacterial Aggregate (CA). CA-attached bacteria play a significant role through different blooming stages with substantial variation of their taxonomic structure. However, little known about functional variations and links cyanobacteria due to the lack reference genomes. In this longitudinal study, we coll...

Abstract While warming and eutrophication have increased the frequency magnitude of harmful cyanobacterial blooms globally, scenario for many eutrophic tropical freshwaters is a perennial year-round bloom. Yet, drivers persistent are less understood when conditions such as light, temperature, nutrients favor cyanobacteria growth year-round, especially in regions facing recurrent periods drought...

The cyanobacteria (blue-green algae) are an ancient and ubiquitous group of prokaryotes that form dense growths or blooms in eutrophic water bodies. The blooms are of interest to aquaculturists and water management authorities due to their production of taste and odour compounds and/or potent natural toxins. The study focused on method development for toxin extraction and detection in cyanobact...

Proliferation of toxic cyanobacteria in waterways is a significant global problem. Environmental stressors, including metal toxicity, can affect algal growth and metabolism. There is a need to understand the influence of environmental stressors on the formation and regulation of both cyanobacterial blooms and toxin production. This review will investigate the effects of metal stressors on cyano...

Eutrophication process and, more recently, global warming have been considered major factors in disturbing aquatic ecosystems dynamics, leading to a shift in plankton communities and to the dominance of cyanobacteria worldwide [1]. As a consequence of cyanobacterial blooms, the impairment of water quality has lead to high costs in economy, mainly due to losses in fisheries and tourism industrie...

The sudden appearance of toxic cyanobacteria (CB) blooms is still largely unpredictable in waters worldwide. Many post-hoc explanations for CB bloom occurrence relating to physical and biochemical conditions in lakes have been developed. As potentially toxic CB can accumulate in drinking water treatment plants and disrupt water treatment, there is a need for water treatment operators to determi...
