Bread Mold

Proposal: Brock and I chose to do our experiment on bread mold. We chose this because we would like to know which type of bread would last the longest and which one would mold the fastest. The Brand of bread we are using is just Kroger. The Temperature for our bread mold is just room temperature for all of them. To make this experiment go by faster we will drop a little water on all the bread so it speeds up the process for mold to grow. (What brand of bread are you using for this experiment?-Austin Ulick) (What type of bread are you using? White, wheat?)
Background:Some of the common bread molds are Penicillium, Aspergillus, Rhizopus, Monascus, and Fusarium(ezinearticles 2007). If you did not know bread mold is not good for you, like for example some molds are poisonous and could cause vomiting or worse in other cases. Mold takes food and nutrients from the bread and causes damage to the surface where it lives( ehow 2012). Mold spores can be destroyed by cooking, that is why mold does not grow right after you make bread(ezinearticles2012). Mold that grows on bread is usually a greenish, Blueish color. All of the conditions needed for mold growth (food sources and appropriate temperatures) are present in the indoor environment with the exception of adequate moisture. (Public Health 2012). Mold seeks MOISTURE, WARMTH, and FOOD, and all three conditions are necessary for it to grow. Mold is most likely to find a place to grow in a bathroom, basement or kitchen, but it can grow in other rooms if conditions are favorable.(moldtips 2002). Since mold is a fungus, it is made of many cells (unlike bacteria which is single-celled). They have an appearance like that of shiny mushrooms which can be seen under the microscope. Though, some molds can be observed with the naked eye as well. (Bread Mold Facts 2012)


How much is a little drop of water?J-Urban
(What are the temperatures of the rooms the bread will be in?~Samuel Garrard)
Our Steps:We plan to take three types of bread ( wheat, white, multigrain) and put them each in seperate bags and let them sit in the same room. We will check the bread for mold daily over a 5 week peroid and record the data.(You need to get more types of bread.-Max Everhart)

By doing this steps hopefully we will find out which bread last's the longest so the next time we buy bread we can save money by getting the best bread.

(Will you test multiple pieces of bread for each type? Rest) we will have two slices for each type of bread.
You should add more controls(Stachnik)

Hypothesis: If we put our 3 different types of Kroger brand bread (Wheat, White, and multigrain) in lunch baggies at room temperature, then wheat bread will be the last one to grow mold.

Materials:
Kroger Brand White Bread (2 slices)(Why Kroger brands?? Why not Walmart... McCoy 1/11/13)
Kroger Brand Wheat Bread(2 Slices) All of the Breads have to have the same expiration date
Kroger Brand multi grain Bread (2 Slices)
3 Plastic baggies (make sure they can be sealed shut and you can see through them)
A room That stays at around 70F(Why around this temperature? Schrock 1/11/13)
Measuring cup of some kind ML
Water
Rubber gloves
paper towels
sharpie

Data Table: In the rows we will record if bread mold starts to grow and what kind it is.

the constant bread is the bread outside the baggies without water
Procedure:
Step 1: First you will need to take one slice of each bread and put each one of them in there own baggie
Step 2: Next you will add 3 ML of water to each of the baggies and seal them shut (Label each bag with sharpie) make sure to take out as much air as possible and make it air tight(will the bag have any oxygen left in it or will you push all the air out of the baggie before you seal it? Baele 2-5-13)
Step 3: Take the other 3 slices of bread and set them each on there own baggie(label on paper towel what kind of bread it is) these 3 slices will be your constants
Step 4: Put all the bread in one room at the same temperature
Step 5: Record your data for ten days
Step 6: Make chart and compare data

Analysis: Our results were that the Kroger Wheat Bread (with water on it) and the Kroger Multi grain Bread (with water on it) grew mold first before the Kroger White bread (water on it) and all the other constant breads. The mold didnt start growing until day 11 which was .4 percent. Then a mouse or mice got into the place we put our bread and contaiminated it and ate through the baggie and ate the bread.

Conclusion: We recorded our results everyday and we didnt get mold until day 11. The breads were Kroger Wheat Bread and Kroger Rye Bread that grew mold first. They grew .4 percent of mold. But instead of just the wheat bread growing mold first, like we said in our hypothesis, the wheat and rye bread grew mold. We couldnt continue recording because a mouse or mice got into the place we put our bread and ate through the baggie and contaminated it and ate half the bread. So we didnt want to touch the bread anymore so we were told to throw it away.
