Cyanobacteria In The Controlled Column

Improved Essays
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 green/blue colour near the top of the column. The reason that it is at the top is because this bacteria photosynthesises using the sun. The side facing the window(the sun) has more of a green colour because the bacteria requires the sun in order to survive.

There are two types of succession. The first one is called Primary Succession and it is the introduction of a new habitat that hasn’t been colonized in the ecosystem. The second one is called Secondary Succession and it is the changes that occur upon already colonized habitats that are disturbed by damage. An example of Secondary could be a forest fire. (10)

Not all types of bacteria appeared at the same time. The starting environment of each column allowed a specific type of bacteria to begin growing. This bacteria caused a sort of ripple effect as it was the cause of other bacteria to also begin to grow.

The chemical hydrogen sulfide produces a smell like rotten eggs. (9) The bacteria that gives off a smell like this is the Sulfate-Reducing bacteria. This makes sense because the Sulfate-Reducing bacteria is only found in the columns that contain Sulphur and those are the three darkest columns out of the five. This is why when those three columns are opened up, they are the only ones that will give off the rotten egg

As three out of the five columns contain Sulphur, there is a large amount of bacteria that is only available in these three columns. Bacteria such as Sulfate-Reducers can only live in an environment with sulphur because they breathe sulfate and nothing else. Sulfate-Reducers are very strong bacteria that are filling up most of the columns with added sulphur. The Sulfate-Reducers in the C+S Dark column is so strong that it makes the entire column anaerobic showing how much sulphur can contribute. Another bacteria that is only available with sulphur is Chromatiaceae. Chromatiaceae gives off the red colour in the columns and it is also known as the Purple Sulphur Bacteria. They only use hydrogen sulfide to survive. Also, the sulphur brings out Beggiatoa which is a bacteria that is only available in a sulphur-rich environment. Many of the bacteria seen in the columns were only possible because of the added sulphur.
-In the C+S columns, there is a mix of a sulphur environment and a natural environment (made by the carbon). However, the sulphur is a very toxic substance which can overpower the carbon. That is why a lot of the columns that include both are mostly black because of the Sulfate-Reducers. However, in the C+S Light column, the carbon creates enough of a natural environment to allow photosynthesis to occur at the top of the column. This is why Cyanobacteria

    The production rate of S2O32- when SoxF metabolized sulfide was similar to that of the wild strain C. pinatubonensis JMP134 (Fig. 2), indicated that knockout of SoxF did not affect the function of the SQR/PDO/ST system. In addition, the double knockout strain CpSQR&SoxF produced almost the same amount of S2O32- and SO42- compared with CpSQR (Fig.S3), which also showed that SoxF did not participated in the oxidation of sulfide. Interestingly, the re-consumption rate of S2O32- (Fig. 2, F), which is produced by SoxF metabolizing sulfide, was much slower than that of wild strain C. pinatubonensis JMP134 (Fig. 2, A), combined with the fact that continuously accumulated thiosulfate produced by SoxYZ, SoxB or SoxXA oxidized sulfide (Fig.S1),…

    The size of the single colony observed is small for both Petri plate 1 and Petri plate 3. Most of the morphology of bacteria in Petri plate 1 and Petri plate 2 are the same except for the appearance and optical property. The appearance of bacteria in Petri plate 1 was dull while for the Petri plate 2 the appearance was glistening. Another difference is bacteria in Petri plate one has translucent optical property while bacteria in Petri plate 2 was opaque.…

    As it can be seen in the previous figure, the Bubble Column PBR is a simple conceptual design. The figure simply illustrates the basic flow in the column. The gas enters the bottom of the column through a diffuser causing the gas to break into thousands of small bubbles making it easier for the algae to absorb the carbon dioxide in the gas. Once the algae have consumed as much carbon dioxide as it can, it releases oxygen in the form of gas, which leaves the column through the opening in the top and returns to the atmosphere [7].…

Once I examined the gram stain it showed that it was a positive and that the arrangement was cluster like and when I compared that to the unknown bacteria data table it showed that both the shapes and arrangements match. That helped me to narrow it down drastically since it was the only one that was shaped like the way it was. My biochemical tests matched perfectly with Enterobacter aerogenes.…

    Caulobacter Crescentus is a dimorphic, α-proteobacterium found in oligotrophic environments. Their dimorphic cell cycle produces two morphologically and functionally different daughter cells, known as the stalked cell and the swarmer cell. The stalked cell remains anchored to the substratum and is sessile, while the swarmer cell is motile. Upon chemotaxis, the swarmer cell disperses in search of nutrients. Once sufficient nutrients are located the cell cycle can continue.…

    Pglo Lab Report

    Purpose: The overall goal of this lab was to perform a procedure on E. Coli which involved transferring genes that encoded for the green fluorescent protein into E. Coli to see if the transferred genes would make a difference on the growth and whether or not the bacteria would glow under UV light. Hypothesis: If the bacteria with the pGLO plasmid was grown on a plate containing LB and ampicillin then the bacteria will grow but not glow under UV light. If the bacteria with the pGLO plasmid was grown on a plate containing LB, ampicillin, and arabinose then it will be able to grow and glow under UV light. If the bacteria without pGLO plasmid was grown on a plate containing LB and ampicillin then it will not be able to grow or glow under UV light.…

    Identification of bacteria can be a difficult process due to the fact that individual bacterial cells can possess similar structural morphology to other types of bacteria. As we have demonstrated in previous lab experiments there are key biological and chemical processes that are characteristic to different types of bacteria. Using various biochemical tests we can evaluate and detect these different processes to aid in our identification of unknown bacterial samples. The implications of these test results can be applied in the medical world when determining an agent responsible for an infection and the cause of disease. Use of an optimal decision tree to sort the results of biochemical tests helps to identify an organism while using as few…

    Introduction: Genetic transformation is used in many areas of biotechnology. In medicine, diseases caused by defective genes are beginning to be treated by gene therapy by genetically transforming a sick person’s cells with healthy copies of the defective gene that causes their disease. Genes can be cut out of human, animal, or plant DNA and placed inside bacteria, which could treat a person with that disease. For example, a healthy person’s gene for the insulin can be put into bacteria. Under the right conditions, the bacteria can make useable human insulin.…
