A Proposal to Research the Effect of Various home base Substances against bacteria from the Mouth

Abstract
Our hypothesis was that green tea testament conquer bacterial growth better than any another(prenominal) bacteriacide substance. We used sterile swabs to obtain a sample of bacteria cells from our mouths and then we swiped the swabs onto nutrient agar Petri dishes. We used sterilized tweezers to drench paper disks into one and only(a) of various substances: green tea, orange juice, distilled urine or mouth wash. We placed two disks in the Petri dishes, one on each side; one disk was slicked in the distilled water (the control) and the other was saturated with one of the other substances. After that we sealed the dishes and placed them upside down at room temperature in doubled plastic bags for 5 days. Upon observation, the gargle had prevented bacterial growth altogether, but the orange juice had change magnitude bacterial growth. The green tea had also inhibited bacterial growth, but not as well as the mouthwash. We will repeat this experiment again, and include more substances such as garlic and cranberry juice. We will also look at the bacteria under a microscope and see which ones atomic number 18 Gram interdict and Gram positive.
Introduction
Of all the types of microbes living in your mouth, bacteria are the close to abundant.



It has been assessed that there are over 100 gazillion bacteria in every drop of saliva, from more than 600 distinguishable species. In fact there are so some(prenominal) bacteria that scientists at Kings College Hospital in London ascertained an entirely new mouth bacteria species. The types of bacteria in your mouth are numerous and it includes strep mutans (S. mutans), Porphyromonas gingivalis, Staphylococcus epidermidis, Streptococcus salivarius, and Lactobacillus sp. unless there are open wounds or cuts inside your mouth, most mouth bacteria will do you no injury (Arnold). Bacteria are one of the main reasons why we see halitosis, better known as bad breath (Gately).
