Cyanobacteria

Is the Growth of Microcystis and Lake Water Protists Affected by Phosphorus Concentration? _______________________________________ Purpose The purpose of this experiment is to determine if algae will grow more if fertilizer is added to the water where the algae is growing. Background/ Introduction An algal bloom is an increase and accumulation of algae in freshwater or salt water systems. Most algae blooms are caused by blue-green algae. Blue-green algae is actually not algae at all, it is a cyanobacteria. A bloom can lead to a green, blue-greenish or reddish discoloration of the water, and if the algae bloom lasts long enough streaks or scums may appear on the water surface. (UBA. 2016) One harmful element of algae blooms is that they…

channel. Initially the bacteria was fed bicarbonate and baking soda which contained CO2, they used baking soda that contained radioactive carbon as this enabled them to accurately measure how much carbon the bacteria was fixing. After a couple of hours the scientists brought in the viruses, the result of which was that carbon fixation stopped, and reported that bacteria which were infected with the phages of the English Channel and Red Sea fixed 4.8 to 2.3 less carbon as compared to the hosts…

asthma exacerbations and GI illness. The different points of entry makes it sometimes difficult to determine and diagnose if an illness is caused by an HAB. 4. Summary of conditions in the Gulf of Mexico contributes to the overgrowth of phytoplankton. • Agricultural waste inadequately treated or untreated sewage and other urban pollution flows into the Gulf of Mexico along with runoff from hog and poultry farms containing nitrogen allow the takeover of surface water by phytoplankton or other…

What are some common symptoms of food poisoning? Based on those symptoms, which dinoflagellate do you think is responsible for the outbreak? A bloom of dinoflagellates can change the water color colloquially known as red tide. Red tide can infect shellfish and cause shellfish poisoning if people eat the bad shellfish. Some symptoms of shellfish poisoning are nausea, vomiting, and diarrhea Explain how an HAB outbreak can have a devastating economic impact. There would be a bad impact on…

The emergence of cytochrome oxidase is considered to be a very important event in evolutionary history. However, not much is known on the development and emergence of this enzyme. Molecular data demonstrates how cytochrome oxidase emerged before the divergence of archaea and bacteria, and well before the great oxidation event. This paper proposes a research plan to investigate the origins of cytochrome oxidase. Background Throughout the three domains of life, a variety of metabolisms are present…

A niche is the role or part that an organism plays in it’s specific ecosystem or habitat. An example would be a sunflower. The sunflower inhabits a grassy area and the role that it plays in the area is that it is the producer that gives off energy to the other trophic levels that also inhabit the grassy area. (1) In total, I found 7 different kinds of bacteria in the columns. (2) -In the Controlled Column, I found Cyanobacteria (5) along the top of the column. This bacteria causes the lighter…

different effects that various pH levels have on the growth of cyanobacteria, by testing various concentrations of nitric acid in different samples of cyanobacteria of equal masses. My hypothesis is that acid rain will greatly affect the growth of cyanobacteria. The higher the acidity level of the water, the less the cyanobacteria will grow. I chose this topic because due to human activities, many different chemicals have been released into the air and they changed the mixture of gases in our…

Lipid metabolism occurs with phosphoenolpyruvate (PEP) as a common substrate in many different fatty acid and protein biosynthetic pathways. The functionality and lifestyle of cyanobacteria lead to many routes to alternative energy. Current investigations The most viable biofuels are typically ones that use sustainable biomass feedstocks that do not compete with food crops, both directly (i.e. corn or soy for biofuels) and indirectly (i.e. land competition), and also reduce greenhouse gas…

Cyanobacteria’s population growth rates seem to increase as nitrogen concentration decreases in June and continues to do so until its population growth rates start to decrease around August as nitrogen concentration begins to increase again. Because some cyanobacteria are capable of fixing nitrogen, they are able to still grow despite there being such a low concentration that the population growth rates of the Diatoms, Green Algae, and Dinoflagellates has decreased dramatically or is at 0 since…

Inquiry Question: Module #6 Chapter 11 Books cited: Becker’s world of the cell: J. Hardin, G. Bertoni, and L. Kleinsmith: 8th edition; pgs.298-299 & 301-307. Question #2 from D2L: The endosymbiont theory attempts to explain the evolutionary origin of eukaryotes. Describe this theory in a paragraph. Be sure to use these terms: semiautonomous organelles, symbiotic relationship, protoeukaryote, purple bacteria, cyanobacteria, mitochondria, and chloroplasts. Through research it was…
