Staphylococcus Epidermidis Essay

After several tests for unknown Bacteria, our group found the unknown is Staphylococcus epidermidis. This bacteria has gram-positive. After we got the result from carbohydrate fermentation test, citrate agar slants, and TSI test, we knew our unknown could be Staphylococcus epidermidis or Micrococcus roseus. These two bacteria have gram-positive; they give the same result but accept Lactose reaction. Staphylococcus epidermidis and lactose product acidic and Micrococcus roseus is not. At this time, we decided to test our unknown by MAC, MR, VP to make sure Staphylococcus epidermidis is correct unknown bacteria. Lastly, the result came out as expected, our unknown bacteria is Staphylococcus epidermidis.

Staphylococcus epidermidis bacteria are usually harmless to the skin and rarely causes disease in healthy people. These bacteria form a biofilm thickness; can bind to the polymer surface. Staphylococcus epidermidis is one of the leading causes of sepsis in the hospital and are becoming increasingly resistant to antibiotics. …show more content…

Additionally, because some bacteria react with methyl red can change the pH. Therefore, in wastewater treatment, people use aerobic bacteria to discolor and detoxify methyl red in wastewater. In this treatment they use bacteria to treat methyl, it is deposited with our test, that we used methyl red to find bacteria. The lab and the treatment have the different target but they have the same
