Introduction:
Topic:

Question:
Does cinnamon and curry inhibit the growth of bacteria?
Hypothesis:
Cinnamon and curry do inhibit the growth of bacteria.
Cinnamon inhibit growth better than curry does.
Aim:
• To see if cinnamon and curry are potent agents in fighting diseases
• To compare the ability to inhibit bacterial growth between curry and cinnamon
How:
I plan to use agar plates in my experiment. There will be a group of 3 petri-dishes: one with just bacteria, another with curry added onto the bacteria and the third one with cinnamon added onto the bacteria. I will observe the dishes over a period of about a week and compare the three dishes at the end of the time period to get my results. I chose the topic …show more content…

It shows which spices is the strongest at inhibiting bacterial growth.
Limitations of the source:
It tells me about the essential oils that each spice contains that makes them inhibit bacterial growth. That information is not useful to me because it is not what my experiment is about. The source is only limited to a few spices and some of which I am not using in my experiment.

Cinnamon has numerous health benefits. Cinnamon enhances the ability of insulin to metabolise glucose, which helps control sugar levels. Essential oils found in cinnamon are shown to inhibit bacterial growth and naturally preserve food. Its anti-microbial properties have also shown to effectively eliminate the Candida strain of bacteria. Cinnamon extracts have been used medically to treat gastrointestinal problems and can be used to combat diarrhoea and morning sickness. The organic compound Cinnamaldehyde has been shown to have anticoagulant effects in the blood, thus eliminating any unnecessary clotting and viscosity in blood …show more content…

Spices should exhibit antibacterial and antifungal activity. Microbiologists and food-product developers have conducted laboratory experiments that involve challenging numerous foodborne bacteria, fungi, and yeasts with phytochemicals extracted from spice plants. Multiple techniques have been used. Nevertheless, it is now clear that many spices have potent antimicrobial properties (e.g., Hargreaves et al. 1975, Shelef 1984, Deans and Ritchie 1987, Zaika 1988, Beuchat 1994, Nakatani 1994, Hirasa and Takemasa 1998).
We were particularly interested in the ability of spices to inhibit bacteria because bacteria are more commonly incriminated in foodborne disease outbreaks than yeasts or fungi (Varnam and Evans 1991, Todd 1994). All 30 spices for which we located laboratory test results were found at some concentration to kill or inhibit at least 25% of the bacterial species on which they had been tested, and 15 of these spices inhibited at least 75% of bacterial species Garlic, onion, allspice, and oregano were found to be the most potent spices: They inhibited or killed every bacterium they were tested on.
