Biolfilm Case Study

Biofilm Case Study 1. Legionnaires Disease is caused by the bacterium called legi acella. The bacteria grow best in cordially water, analogous the kind found in impetuous ad valorem taxs, cooling towers, ardent water tanks, sizeable plumbing systems, or parts of the air-conditioning systems of large buildings. Legi starlla live within amoebae in the natural environment. This is a problem on cruise ships in the whirl pools, hot tubfuls, and cooling systems if they do not cherish these with the proper chemicals to counteract this bacterium from growing and it does anyone can rest in a water droplet and possibly spread it to an new(prenominal) person. 2. (A) The treat light Antibody Test is used to detect the presences of a special antigen (or a particularised protein on the surface of a virus, bacterium, or other microbes). This test works by fluorescent chemicals attaching to the eonian division of an antibody. If the antigen (legionella) is present the antibody binds to generate a very specific protein tag. (B) none of the water samples tested positive for legionella. For the swabbed samples the hot tub was the one that tested positive for the bacterium. In all of the samples the hot tub sample was very bright, highlighted the bacterium whereas the other samples didnt consecrate the same appearance. 3. We set up a standard water system.

It consisted of a series of square PVC pipes with 24 dismissible pieces on one side. Water flows in one hold back and out the other end. We controlled the flow rate, and the national of the water that flows through and through each pipe. Based on my experi! ment here is what I found | twenty-four hours 0| Day 10| Day 25| Control| ++| +++| ++++| centiliter| ++| +++| ++++| Heat +Chlorine| ++| ++| +++| UV Radiation| ++| +++| ++++| Ozone| ++| ++| ++++| Ozone + Chlorine| ++| +_| +++| 4.) The ozone and centilitre would be the treatment I would recommend. Based off the results ozone and centiliter had the least amount of legionella compared to the rest, ozone can be...If you want to wank a full essay, baseball club it on our website: OrderCustomPaper.com
