In ten days you will be able to answer this important question and make a contribution to science! But what is mold? What makes it grow? What is Mold? Mold is something that we often take for granted, as something that makes us have to throw the bread away or the cheese smell bad. Mold is, in fact, a fascinating organism which has had many different uses over the years and our lives would not be the same without it. Most of us know that food seems to become moldy more quickly in the summer than in the winter when it is colder. Food in refrigerators seems to keep longer than food left out in the sun. Is this true? Does temperature really affect the rate at which mold grows? Important Note Please note that some people are allergic to mold; …show more content…
Any sort will do but it is perfectly fine to use cheap white sliced bread as then you will know that all of the slices are a similar size, weight and thickness. You must make a note of the brand and use-by date so that anybody else wanting to repeat the Mold Bread Experiment can use the same type. 15 sealable sandwich bags 1 piece of film or clear plastic with a 10x10cm grid drawn onto it Q-Tip Clean knife Chopping board Sticky labels Marker pen Mold Spores - if you can’t get these from your school don’t worry. There are mold spores all around us in the air which will eventually grow on the bread but your experiment will take longer. Mask Gloves Method Using the sticky labels and the marker pen label the bags. Mark 5 bags as ‘A’, 5 as ‘B’ and 5 as ‘C’. You also need to label each set of bags 1 to 5. Cut the bread into 10 x 10 squares using the chopping board and knife. Inoculate the bread thoroughly with the mold solution. Try to coat each slice with a similar amount of the culture although this can be
The possible Fungus spores could pose a health risk based upon data from the NYDHS study, Harry Dobin’s autopsy, and experts in the field. Additionally, the Fungus, presumably, is the cause of the public nuisance (i.e. the odor) and the Fungus spores are the result of Landfill’s
The 1920s was a hard and painstaking era in American history. Many family's throughout New York lived in absolute poverty and saved week to week just to make enough to eat and pay the rent. Many Immigrants flooded the streets desperate for work while living conditions were harsh and many starved. This is just the case of the novel Bread Givers, written by Anzia Yezierska. In this story we follow Sarah Smolinsky, an ambiguous independent Jewish girl "trapped" by her religious traditions. Her story unfolds as she breaks away from her controlling parents and moves to work and go to school for hopes of being a school teacher. Her life is not easy and she must endure countless sacrifices just to get by. With the determination of her will she graduates college, but returns to her father to take care of him in his old age. In the begging of the story Sarah hates her father, and everything about him, and this relates to her hatred of his God and his traditions. From hatred of her father she refuses her Jewish traditions and religious beliefs to make a better life for her self in America. After accomplishing her goals, she can't ignore the emptiness of her fathers love. Sarah yearns with a wanting to be loved by her father. She begins feels remorse for him, and starts to remember her past and where she came from, returning slowly to her once lost traditions.
Some people think back to middle school and say it was the boring school years. However, for me it was great, and one class made my experience even better. That class was Ms. Royall’s home economics class. She is well-known for her monkey bread, and I fell in love the first time eating it. In her class, the first thing we learned was how to make monkey bread. We would make it all the time, and would always fuss about someone getting more than the other. It is a sweet, delicious dessert that is easy to make. This is now one of my favorite desserts, and I would like to share it with you so you can make it.
The first step of the process of hay production is the standing crop. The standing crops contain bacteria and yeasts. This is where potential mold growth begins (Smith). Once the crop has been cut the moisture of the plant is then decreased very quickly. This now allows a new group of microbes to begin to reproduce and spread. Hay that is apparently dusty but lacks visual evidence of mold, is caused by fungi growing in the cut hay that is drying out in the field. After the hay has been baled, yet another new group of microbes (mainly consisting of fungi and yeasts) start to reproduce (Smith). These new fungi are better suited to fill this new, drier, and warmer niche. The most common molds found in hay include Alternaria, Aspergillus, Cladosporum, Fusarium, Mucor, Penicillium, and Rhizopus each of these types cause spores that can cause problems for livestock and especially horses (Lemus). Out of these common types of fungi, there are three types that start to grow mainly during storage; These are Aspergillis, Fusarium and Penicillium. Several of the fungi that grow during the hay bale storage process are known to produce mycotoxins. These are the organisms that feed off sugars and organic acids emitted from the plant during the drying process and they are also the types of fungi that cause hay to become moldy (Smit...
Rye can be eaten when made as bread or cereal, because it’s an ingredient that is similar to wheat, but sometimes it can be infected by ergot. Convulsive Ergotism is caused by a fungus that takes over the still growing kernels of the rye grain, this is usually caused when exposed to warm or damp environments. One such occurrence affected the rye eaten by Salem residents. Ergot causes people to have violent fits, a crawling sensation on the skin, vomiting, choking, and hallucinations. (The Witchcraft Trials in Salem: A Commentary).
inches). After the initial bread information is gathered, one may commence cutting. Simply slice the entire length of the bread, but do not cut all the way through, to create a hinge effect. The entrée is then ready to be dressed.

Fungi are eukaryotic organisms which are either single-celled or multi-cellular organisms, their DNA containing chromosomes are enclosed in a Nucleus inside their cells. Fungi cell structure is very similar to that of the plants however, Fungi do not perform photosynthesis. Fungi is often known to be a nuisance when found within a person’s house, whether on food, the walls or even the floor. People naturally find it disturbing and dirty, however there are good types of Fungi, often referred to as friendly fungi. In 1928 Penicillin, one of the most famous of antibiotic drugs was discovered having derived it from the fungi called Penicillium. This discovery has since has a huge impact on helping people across the globe. However, not all is it seems, there are some nasty fungi that can cause diseases in plants, animals and people. A famous one being Phytophthora infestans. This ...
In this method, living spores which are resistant to whichever sterilizing agent is being tested are prepared in either a self contained system, such as dry sp...
Mold is a member of the fungi family. Since mold is part of the fungi family, it cannot use the sun to obtain energy. This means that mold has to use other plants or animals to grow. Even though they cannot see them, there are millions of mold spores in the air. These spores settle down and start to multiply which can be done rapidly or slowly as long as it has a food source. Mold usually grows best in warm environments, but it can still grow in cold environments also. Mold can cause illness such as vomiting or feeling nauseated when it is eaten or when it smells bad.
The slime mold has a simple environment. They can be found in cool, damp places were they can easily find food. Most species that feed on decaying organic matter, bacteria, protozoa, and other minute organisms, which they engulfs and digests. They may live on plants, but do not try to kill the plant to eat. They do not mean to harm the plant, although they sometimes smother the plant in which they are living on by not allowing sun light reach the leaves.
There were five test solutions used in this experiment, water being the control, which were mixed with a yeast solution to cause fermentation. A 1ml pipetman was used to measure 1 ml of each of the test solutions and placed them in separated test tubes. The 1 ml pipetman was then used to take 1ml of the yeast solution, and placed 1ml of yeast into the five test tubes all containing 1 ml of the test solutions. A 1ml graduated pipette was placed separately in each of the test tubes and extracted 1ml of the solutions into it. Once the mixture was in the pipette, someone from the group placed a piece of parafilm securely on the open end of the pipette and upon completion removed the top part of the graduated pipette.
Food advertisements, supermarket displays, and restaurant menus increasingly highlight foods, particularly bread, as being gluten-free. Gluten consists of two proteins, gliadin and glutamine, which combine and help produce light and fluffy bread (Lord, 2012). Wheat is bred for its high gluten content which serves efficiently well for all bakers and chefs. Today, gluten is becoming a problem in society since allergic reactions to the protein have increased. Bread is a worldwide staple food and gluten is a predominant aspect within the dough mixture. Gluten free bread is basically fixed as it was thousands of years ago without the fermentation of yeast and the mixture of sourdough.
...h a tight fitting lid. This will cause a small amount of carbon dioxide to build up which will minimise mould growth.
Our planet, the Earth, is the third planet from the Sun, and usually is known as the Blue Planet. Its location in the Solar System and the particular characteristic of being the only planet with abundant water, have made possible the development of life here. Thousands of millions of years ago, the first living organisms evolved from a non-living matter, and since then the Earth has been inhabited by many different species. Those, who have dedicated their research to study and classify living organisms, best known as taxonomists, have divided them into categories, taking as a definition pattern the principal features of each species. In this manner, the living organisms can be classified into five Kingdoms: Animal, Plants, Fungi, Bacteria,
