The main focus of this experiment is to observe the difference in mold growth between
slices of bread that were handled with dirty hands and with clean hands. As a control test there
was one slice of bread that was not handled by human hands and was only touched with clean
Germs were first discovered by Louis Pasteur. In 1850, Pasteur first started investigating
why beer at a factory was turning sour. In his work to determine the cause, he put a sample of
the beer under a microscope. This is when he found thousands of microorganisms that was
living in the beer. These microorganisms are what we call germs. He went on to continue to
study different liquids and the presence of germs in them. Pasteur then came to the belief

Joseph Lister knew of Pasteur’s work and took it a step further. Lister researched how
there was a connection between post-operative death and infection and how clean the hospital
conditions were. Most of the steps he came up with for use in surgical rooms to prevent the
spread of germs and infection are still used today.
FACTUAL SUMMARY
Mold is a fungus that can be found anywhere. Mold grows best in conditions where there
is moisture and warmth. Just like germs, mold spores are easily spread. Mold can be spread by
spores in the air, it can be spread by being attached to people and/or animals. The similarity of
how mold spores spread and how germs spread is the reason for this experiment in order to
evaluate how the cleanliness of your hands affects the spread of mold or germs.
Hospitals and the CDC (Center for Disease Control) have strict guidelines about how you
should try to prevent the spread of germs by using good personal hygiene. Lucy Moore, a nurse
at Sumter Surgical, says that one of the most important steps you can take to not spread germs is
to wash your hands. She stressed that you need to use soap and warm water and to wash
In addition to diligent hand washing and the consistent use of other Standard Precautions, which measure will help reduce the transmission of Hepatitis?
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. The climate where you live and the living habits in your household can affect the ability of mold to grow. Mold spores can thrive and reproduce in wet or damp parts of your home: areas that have had flooding or where leakage has occurred in roofs, pipes, or walls, or areas around house plants, especially ones that sometimes are over-watered. In just 48 hours, a moist environment combined with room-temperature conditions and an organic food source can lead to mold growth.
The main concern behind most types of mold is respiratory health and can be especially dangerous to individuals with pre existing respiratory illnesses and also childs, kids and teenagers still in the developmental phases. Troubles breathing, coughing and sore throats are all basic effects mold can have on the body including other allergy type symptoms such as nasal irritation causing sneezing, runny or stuffy noses. Mold also opens people up to becoming more susceptible to fungal infections with can be deadly. Long term exposure to black mold can cause more severe reactions such as nausea, vomiting and bleeding and chances are at the point it has already damaged the house too. Water is often the main catalyst in the growth of mold as it is often all a mold spore needs to reproduce. Water covers the majority of the earth, makes up the majority organic compounds and is essential to life. It is in the air we breathe, the houses we live in and can be hard to control. It can form on windows, pipes and many other materials when the conditions are right and this often goes unchecked. Pipes can drip water from spots we generally don't even see to begin with into even harder spots to reach. Water can also travel in the form of steam and condensation into the smallest nooks and crannies of a house. It can soak into carpets, drywall and other porous materials that will
Mold can cause a lot of symptoms, including fatigue, headaches, and allergies. The tips above can help you combat these symptoms as well as keep mold growth at bay. In an ideal world, you will find dry times to open your windows and doors to let fresh air into your home throughout winter. This will introduce new air and force some of the toxins

Two of them were Emile Roux and Charles Chamberland. He had heard about the work of another scientist, Edward Jenner, who had found a vaccine for small pox. Louis investigated the vaccine and how it worked by exploration and discovery. He didn’t know how Edward Jenner’s vaccine worked, so he just guessed and check, or exploration and discovery. This consisted of inoculating chickens with different cultures of the chicken cholera. They discovered that the old cultures made the chickens immune to the
The best time to test for mold is after experiencing water damage such as a leak, which makes growth much more possible. A bad storm or a hurricane can accelerate the damage even further, especially in the event of a flood. Biosweep technicians are equipped to both identify and treat mold, as well as perform water damage repair to stop mold in its tracks.
Yes, mold is essential to the well being of our environment and without it, we would not have life saving antibiotics like penicillin that would exist and scrumptious soft cheeses like brie would not be here for us to spread on pieces of toasted french bread that compliment our favorite glass of wine. Mold is necessary for the break down and decomposition for all of natures organic matter, which helps recycle nutrients as well as gets rid of the build up of decaying matter and allows new vegetation to grow. Mold does a lot of good for our planet but unfortunately, it can also cause a lot of harm, especially if it begins to grow and spread undetected in your home.
Louis Pasteur's discovery of the relationship between germ and disease was only the beginning to developping a permanent solution. The theory led to the realization that handwashing helps prevent the spread of disease and disinfection can eliminate germs. Disinfection and handwashing affected humanity because the rates of infectious disease began to decline and epidemics lasted for a shorter time spand and overall mortality decreased as a result. The introduction of the theory affected how humanity viewed the human body. People began to believe that dirt contained microorganisms and could cause an infection, which lead to bathing frequently. Alongside his discovery were his inventions, for example the machine used to screen and detect silkworm eggs which saved the European silk industry and helped prevent silkworm
the beginning of war times2. They used anything they could to grow mold in vast quantities. From bathtubs to milk containers
Can household mold make you sick? If you are asking yourself this question, then what you must know is that molds are those tiny organisms that are actually found everywhere. They can have different colors, such as orange, purple, green, or white. When it comes to outdoors, that's the place where mold plays a very important role, due to the fact that it breaks
I am currently reasearching what is mold and the effects of mold. Moulds are microscopic fungi that survive by feeding off organic matter. Scientific estimates believe the amount of different types of fungi range from tens of thousands to perhaps 300,000 or more. Most are threadlike organisms and the production of spores is a characteristic of all types of fungi, not just certain types. These spores can be transported by air, water, or insects. The spores are constantly floating through the air however at that point are invisible to the naked eye, once they find a suitable environment with food they grow and become noticeable. The green colour shown by the fungi is the spores. Certain types of fungi grow mycotoxins which are hazardous to human
There have many differences between molds and yeast in term of morphology, energy production, reproduction and the uses. (Mold vs. YeastMold vs. Yeast, 2013)Molds are long cells which look like threads and consists of long, branched and threadlike filaments of cells called hyphae whereas yeasts have the round or oval in shape. Molds are multicellular and filamentous that reproduce either by sexual or asexual to produce small spores. While for the yeasts, it are unicellular and reproduces asexually by budding or binary fission in which the nucleus is divided into two or more nuclei to produce a new yeast. Besides, molds are usually used in the production of food and drinks such as soy sauce and cheese and can be found in damp, dark or steam-filled
The information gathered in this experiment may be relevant to those individuals who contend with food borne molds at home, or professionally. Because the rate of mold growth can vary depending
It all began when Anton van Leeuwenhoek invented a microscope and began observing objects under it (Boundless, 2015). The theory of microorganisms existed prior to Leeuwenhoek’s discovery of them but they were never documented, just imagined. Leeuwenhoek was the first person to see and explain a single celled organism, bacteria and even how blood flows in the capillaries (ICO, 2015). Robert Hooke was actually the first person reported to view a microbe under a microscope and even discovered the cells of plants. Multiple experiments were done including and experiment that proved that there are bacteria in the air contaminating things all around us. Broth was boiled and one pot was exposed to the air while the other pot was not (History, 2012). The pot that was exposed to the air showed that there were bacteria and life forms present; giving reason to believe that there were some sort of microbes in the air, some of which can cause disease and some that are harmless. The harmless microbes are actually extremely beneficial to the environment for many reasons (Pelczar, 2015).
