Make daily observations of your bread and track the growth of mold. It should take around days before you will be able to see significant growth on the bread. You could see growth as soon as 5 days depending on the type of bread you used. Remember, fresh bread will mold faster than store-bought bread containing preservatives. Mold spores can cause allergic reactions and respiratory problems. Some mold contains mycotoxins which can cause neurological problems or even death.
Dispose of the bread properly. When you are finished observing the growth of the mold, dispose of the sealed container in the garbage. Do not open the bag. Opening the bag can release mold spores into your environment that are not good for your health. Wash your hands every time after you have handled the bag. Part 2. Make multiple samples of moistened bread. To test various growth conditions for mold, you will need multiple samples. Moisten as many pieces of bread necessary to test your conditions.
Place each one in a separate bag. For example, if you want to test 3 different temperatures, make 3 samples. Before each experiment, make some predictions about what will happen. Make a hypothesis about how quickly the mold will grow under each condition. Write down whether you think there will be more or less mold for each condition at the end of the experiment. Vary the amount of moisture on each slice of bread to see how moisture affects mold. Keep all other conditions the same temperature and amount of light , but add different levels of moisture.
Have 1 slice with no moisture, 1 slice that is just damp, and 1 slice that is soaked in water. Check the samples daily to see if the growth of mold is different between the 3 pieces. Place each bagged bread sample in a different temperature to see how temperature affects mold.
To test mold growth at different temperatures, store 1 sample at room temperature, 1 in the refrigerator, and 1 in the freezer.
Remember, to minimize variability, you will want to use the same amount of water for each piece of bread and store the room temperature sample in the dark, as the samples in the fridge and the freezer will mostly be in darkness. Store each bagged sample in areas with different varying light levels to see how light affects mold.
If you want to test whether or not light has an effect on the growth of mold, store samples in different light environments. Place 1 bag in total darkness and 1 bag in a brightly-lit area. To minimize variability, make sure the temperatures of both environments are the same. Use the same amount of water for each piece of bread as well. Observe your samples daily to check for differences in growth rate and amount. Did you know you can get expert answers for this article?

Especially if you live in an area that gets a lot of rain, your pantry may benefit from a dehumidifier.
A dehumidifier works like a vacuum cleaner for moisture, and it removes the humidity from the air by sucking the air dry. It then blows dry air back into the room. Bread can last longer when it is stored in the fridge; hence if you plan to use the bread for a long time, keeping it in the refrigerator is the best idea.
My wife usually puts all the bread that we buy in the fridge, and they surprisingly last much longer than what they would at room temperature. If you do not plan to use all your bread in a week, then you should consider storing it in the freezer by taking proper precautions.
Storing bread in the freezer will make it last for an extended time. For storing the bread in the freezer, steps must be taken to make sure that there is no room for moisture to escape. By placing bread in a ziplock bag and sucking the moisture out of the bag with a straw can help eliminate extra air and prevent the bread from losing moisture.
You can easily prevent moldy bread by following proper precautions, limiting moisture to escape, and storing it at proper temperatures. Buying fresh bread will enable you to enjoy it for a long duration compared to buying bread that is soon to pass its expiry date. Artisan bread may have extra flour on top, and if it concerns you because it can be mold, it is best to avoid such bread.
Usually, artisan loaves of bread are sold at a discount at the grocery stores since they are costly and never sold out. So, the grocery stores put them on discount to encourage people to buy them before they reach their expiry date.
Hence, artisan bread is at the highest risk of having white mold, which may look like flour because it has probably been sitting on the store shelf for a longer duration. I'm doing this for a science project and it did not work. Well not yet its been like 9 days and I have a peanut butter and jelly sandwich in a closet and another one in sun light neither show mold.
Answer Question. Connect Connect Connect. When the opposite strains grow near one another, special hormones cause them to touch. When they touch, the cytoplasms of their cells combine, and their nuclei meet and join together.
The union of the nuclei cause the formation of a zygospore. This structure has a very thick cell wall and the ability to remain dormant; these features enable a zygospore to survive difficult conditions.
