Cyanobacteria exhibit numerous responses to changes in the intensity and spectral quality of light. What sensors do cyanobacteria use to detect light and what are the mechanisms of signal transduction? The publication in 1996 of the complete genome sequence of the cyanobacterium Synechocystis 6803 ...
Photosynthetic organisms such as cyanobacteria have been shown to exhibit complex transcriptional remodeling with respect to diurnal variation of light availability [1-3]. However, the reported estimates of the number of oscillating transcripts differ strongly between studies and range between 9-80% of ...
Lake Okeechobee is often described as the liquid heart of Florida, and it’s now in cardiac arrest. The state has never come close to meeting its nutrient goals for the lake, but the pollution has gotten worse in the Scott years. Last year was the worst ever, as Hurricane Irma and o...
There, a microscopic battle between two kinds of bacterias - oxygen-producing cyanobacteria and white sulfur-oxidizing bacteria - would play out, scientists say. In the early days of Earth, the sulfur-eating bacteria would physically cover the cyanobacteria every morning and evening, blocking ac...
FishLab Fact:The“lower nitrates are better”rule is thrown out the window if you have a planted aquarium. Many plants use nitrates for food, and in this case, low nitrate levels can actually cause problems and can even lead to ablue-green algae(cyanobacteria) outbreak. ...
Scientists think that around 2.7 billion years ago, photosynthetic microbes called cyanobacteria were able to use the sun's energy to convert carbon dioxide and water into food, leaving oxygen gas as the waste product. The presence of oxygen caused more complex life forms to flourish. While ...
For a more likely glimpse of an Earth-altering cataclysm, we need to look to the distant past. Nearly 2.5 billion years ago, a period called theGreat Oxidation Eventgave us the breathable atmosphere we all now depend on. An eruption of cyanobacteria, sometimes called blue-green algae, filled...
Harel, who had earned his PhD in environmental microbiology, had always been fascinated by cyanobacteria and algae, wanting to understand what made them so successful in the environment—and how to stop them. In 2018, the company he founded,BlueGreen Water Technologies, began tr...
Cyanobacteria, the first photosynthetizers on Earth, might have appeared in water about 3.4 billion years ago [10]. This event may mark the first association of physical, rather than chemical, conditions with a survival strategy. The first predators may have appeared as early as 2.7 billion ...
Top 10 Ways: How to Prevent Harmful Algal Blooms and Cyanobacteria AS SEEN IN Common Ground™ magazine In communities with lakes and ponds, managers need to be vigilant to prevent cyanobacteria –also known as blue-green algae. Algae is a natural component of any lake or pond ...
