Cyanobacteria

Lake Erie’s toxic algae blooms are becoming deadly, all of the local residents need our help. Everything started in the 1960’s in Cleveland, Ohio. Many factories/machinery at that time made lots of pollution that was dumped into the lake on purpose. All of this pollution gave Lake Erie many bad vibes, which led to the nicknames Lake On Fire or Dead Lake. Lake on Fire is due to the Lake catching fire many times. “As a result of these pollutants, Lake Erie contained increased levels of phosphorus…

The article “ When Did Photosynthesis Emerge on Earth?” was written by the principal investigator of the Ames Research Center team of the NASA Astrobiology Institute, David Des Marais. His experience has led him to publish more than 160 technical articles and chapters on many research topics such as the biogeochemical carbon cycle and the early evolution of the Earth and its biosphere. In this particular article, Des Marais establishes that life dates back to 3800 years ago and that not only…

The limiting factors of HNLC are usually no temperatures, light, or cyanobacteria. The melting ice in Antarctica is a limiting factor because there are high levels of iron in dry temperatures. This means that dry areas, like deserts produce high levels of iron, which in turn can be blown into the ocean and produce primary production…

Amazon’s indigenous forest which is in the Amazon forest. Another example is of how the University of Toronto as well as MIT has come up with a project that uses drones as well as high tech sensing technology to look in to and check any form of cyanobacteria in lakes and rivers ("Humanitarian Uses Of Drones And Satellite Imagery Analysis: The Promises And Perils" 2015). This is because the bacteria are very harmful to animals as well as human beings who are dependent on the river for drinking…

Did you know Lake Erie is called the “burning river” or “dead lake”? Sixth of Lake Erie's water was covered in toxic algae. Since so many algae is in Lake Erie it’s spreading to other rivers such as the Maumee river which now only supplies 5 percent. Algaes has now expand across the western Lake Erie shoreline from Monroe to the Lake Erie islands. Algae bloom has been a growing problem now since the 2000s. Unregulated dumping of sewage and industrial pollutants with similar algae blooms and…

In 1969, Thomas Brock and Hudson Freeze of Indiana University discovered a new bacteria species in the Yellow Stone Park, that scientist thought it could not survive above 55 degrees Celsius. Thermus aquaticus is a typical gram-negative bacterium, meaning that its cell walls contain much less peptidoglycan and unlike gram-positive bacteria, gram-negative bacteria contain lipoproteins. T. aquaticus appears as either a rod or short filaments. When exposed to sunlight, it can exhibit a yellow, pink…

Cyanobacteria, one of the photosynthetic bacteria, consist of chlorophyll, whereas the other forms of photosynthetic bacteria consist of bacteriochlorophyll. Although bacteriochlorophyll is similar to chlorophyll, it absorbs light of a broad wavelength than…

What are oceanic dead zones? Dead zones are hypoxic areas in the worlds oceans and large lakes. Hypoxic areas are places that fail to meet the required percentage of oxygen needed for human life. Activities such as littering in the small lakes and ponds can cause dangerous pollution. When oil is released into the water, that can cause an overgrowth in algae which will dissolve to the bottom. They are caused by excessive nutrient pollution from human activities. These activities cause less oxygen…

and metazoa. The monera kingdom consists of primitive organisms which are very small in size and are single celled. These organisms generally consist of prokaryotes or eukaryotes, meaning species such as bacteria, archae bacteria, mycoplasma and cyanobacteria are included. The protista kingdom consists of aquatic, single celled eukaryotes. These eukaryotes are generally photosynthetic, including diatoms, golden algae, and protozoans. The Mycota kingdom (kingdom fungi) consists of mycelium, with…
