Mold Grow Lab Report

Depending on what type of mold it is, depends on how it needs to be disposed of. Mold is harmful to the environment. Therefore, it is important to be disposed of properly. Though you can find out this information yourself, when you hire a professional, you wont have to. They are all highly trained in handling mold and know exactly how to properly dispose of

Molds can even be beneficial in the way that some make our food taste better, like in some cheeses. Rhizopus stolonifer is a common find in your food and is only one in the giant family of molds. Our experiment is to test that if bread is exposed to light, then mold will grow faster because of the increase in heat. This experiment 's purpose is to test the growth rate and conditions of mold. We hope to have a better understanding on the prevention of mold growth. Our manipulated variable will be the amount of light distributed to the bread, the responding variable will be the mold growth, and the controlled variable is the type of bread used in the experiment.

In this project, C. Elegans are hermaphrodite worms that will be used since they are easy to maintain in lab, as well as have short life cycles. The gene that the project attempted to knockdown in C. Elegans with RNAi treatment is the unc-22 gene. RNAi disrupts gene expression in the presence of double stranded RNA (dsRNA) that is complementary to target gene sequence. The unc-22 gene codes for a muscle protein called twitchin in wild-type worms. The Unc-22 is required for muscle regulation and maintenance in C.Elegans. To verify that the RNAi treatment worked, would check the unc-22 mRNA levels in the worms, in addition to phenotype observation.

First of all, you have to determine where the mold occurred, so that you can deduce where the blame lies. You have to consider your regular routine, and the conditions in said places that may have facilitated exposure to harmful breeds of mold. Here are a few examples of places where mold may have occurred, along with some of the probable guilty parties:

During the final experiment for Microbiology will have to figure out the unknown organism given to us. The organisms will be narrowed down by using skills we have learned throughout the lab this quarter and the test results will narrow down to a single organism. The reason to perform experiments that determines the identity of bacterium is to find out how to treat it or what infections it is causing. In a controlled environment, students learned how to use various methods to determine how to differentiate between multiple bacteria. This lab report will be detailed steps explaining how to determine the identity of my unknown organism number 12.

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 will never develop in a dry area with proper air circulation. It needs warm conditions and a supply of continuing moisture. Often, by the time it

How does Mold grow on bread? Well the experiment I did showed me.But, I am gonna tell you guys by all the research I did. So, Mold grows because of small tiny spores that float around in the air. The mold that is on the bread usually grows on cheese, Bread, and other foods. Also, for Mold to grow it is required that the bread should be moist. Also, the best temperature so Mold can grow is 70 degrees fahrenheit and 20 degrees celsius, or more so mold can grow. So, know we know how mold grows but know let's talk about the dangers of eating Mold. So, the dangers of eating moldy bread is dangerous because you could be eating many different types of poisons. Some of the poisons you could be eating are mycotoxins, or fungal poisons. This fungal poisons

As soon as you spot even a small patch of mold in your bathroom, you need to take action. Mold can quickly grow and spread from a tiny patch the size of a dime to a patch that is at least a square foot in a very short matter of time. Due to how quickly mold spreads and due to the fact that some mold is harmful, any mold that shows up in your bathroom needs to be addressed quickly.

Molds are eukaryotic (taxonomic group that includes organisms composed of one or more cells with visible nuclei and organelles) micro-organisms that are decomposers of dead organic material such as leaves, wood and plants. Mold grows by the extension of hyphae, which are considered to be tiny root hairs that extend across surfaces. In this way, small colonies of mold can expand to cover many square feet of material and it can also create spores that allow mold to inhabit the air and spread across various locations. (Moreau, 1974, p.125). The spores and hair-like bodies of individual mold colonies are too small for humans to detect without a microscope. These spores can survive in various conditions, such as hot, cold, dry and moist, and allows mold to grow. When spores are released they can be carried by air or water to new locations. According to Christensen (1975), some spores are so small that they are more affected by air currents than by gravity as it allows them to reach further locations. When spores land on a damp surface that has food and oxygen available, and the proper temperature, they will start to grow. Mold spores are ubiquitous in nature and are present everywhere, in outside air as well as indoor air. Wherever there is decomposing organic material mold and its spores are also present, which makes it

Plasmodial slime mold differs from cellular slime mold in a few key ways in its life cycle. Plasmodial slime molds exist in their feeding phase as a multinucleated plasmodium. In this phase, each individual cell loses its cell membranes, forming a large mass of cytoplasm with up to millions of individual nuclei floating freely within. This mass is able to move along a surface in search of food in an amoeba-like fashion by extending pseudopods. Top speed for plasmodial slime mold is about one millimeter per day.

Life on this planet began with microorganisms. Through millions of years microorganisms have found ways to successfully adapt and survive. These adaptations have created a wide biodiversity, allowing them to basically populate in all places. Why are these microbes so important? Because they shape the history of our world. Some microbes can be deathly to humans while some others are favorable, for example, bacteria that lives in the gut of both humans and animals and helps during the process of digestion (Alfred Brown & Heidi Smith, 2006). Understanding these interactions help scientists to find ways to protect humans from potential deathly pathogens. In order to observe microbes, microscope proficiency and microorganisms’ identification are crucial skills in a microbiology lab. During this laboratory session, samples of environmental and human organisms were inoculated into two different rich media and incubated to their according temperature. After this, appropriate use and calibration of the microscope was performed. Lastly, morphology and size of different species of bacteria, algae, fungi and protozoan were recorded.

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
