This will make the results of this experiment more relevant to average consumers and it will enable the results to be generalized across a larger selection of commercially produced wheat breads. Each container was kept at room temperature with an adequate source of light. HypothesisUnder light, mold will be more abundant on the bread under light than the bread exposed to no light. At Custom Writing Bay, in the provision of bread mold lab report writing assistance, we refer to these filaments as hyphae. Cover cups with plastic wrap 5. Exposure to light was approximately the same each day for both samples.
There was no bread mold on ether pieces of bread. Try to coat each slice with a similar amount of the culture although this can be difficult. For companies using mold to make food or medicine they need to know at which temperature mold grows best. Introduction: Blue Baby Syndrome is a condition that affects many infants. Buy this paper with your credit card or cash balance at PayPal. Check everytime you are in the lab how much mould there is. Bread Mold Growth Lab Purpose: The purpose of this lab is to determine the influence certain variables have on the growth of bread mold over 9 days.
A 50 mL beaker was filled with tap water. Introduction The purpose of the experiment was to know in what conditions the mold most grow and how fast. We just wanted to see which bread piece would mold first, so we did not do any mold measuring. Conclusion: The data does not support my hypothesis on water making bread mold grow. Are there Effects of Mold as Confirmed by Lab Tests? Here is a diagram of bread mold in detail. Label them with a marker. The clocks are believed to be central to understanding some sleep and mood disorders.
It feeds on organic matter like bread while decomposing the same. Notice that it is very blue-green on the bread. Reweigh bread to see the difference in weight 3. Repeat this process with another bag. So, gather the above equipment and follow the below steps. This will make the results of this experiment more relevant to average consumers and it will enable the results to be generalized across a larger selection of commercially produced wheat breads.
Cladosporium bread molds produce a noticeable odor, more so than other bread molds, which may help you to notice these molds before accidentally eating them. They found the bread stored at the freezing mark did not show mold until the twenty-eighth day, but that that the bread stored at 7°, still well below room temperature, showed mold on the ninth day. As much as possible, the two bread samples were treated in exactly the same way. Then pour the milk out into the sink. After all, while bread mold may be a mere annoyance in the pantry, as a research model it ranks with the fruit fly. The amount of light each sample received is thought to be insignificant in terms of impact on the results.
After that we seal up the bags and label them. Black Bread Mold Black bread mold Rhizopus stolonifer is one of the most common bread molds. The scientists used a pipette to suck up some of the water and then drop ten drops of water on the bread squares in the petri dishes. The question the researcher will attempt to answer is how freezing affects the rate of mold growth in wheat bread. The researcher will repeat those measurements for 10 days and summarize my findings at that time. The controlof the experiment was the amount of water and temperature and the independent variable was thelight.
When bread is in a dark environment, mold will grow faster in opposition to a light environment. Determining how long bread can be stored before molding can help save money, prevent illness and preserve freshness. Experimental Design as a Key Factor Designing the experiment is like a road map for the experiment. I would be interested in air as a variable because think it affected my research on water and bread mold. A possible error in this experiment was whether the lowered pH affected the mold growth or a chemical in the lemon juice. Note the light coloration of the mold and its spread into the crust of the bread.
You can take this project further by measuring how much mold is on each piece of bread after a certain number of days. Neither you, nor the coeditors you shared it with will be able to recover it again. Mold goes into a dormant state when the conditions do not allow growth andthen proceed to reproducing and growing when the conditions allow. March 26, 2013 Methods and Materials Bread Mold Lab Block 1 The materials needed to conduct this experiment are six small squares of bread, a container of milk, four small Ziploc bags, a thermometer, a phone to record data and a heat lamp. Daphny Maldonado Bio Lab 2107 Kiah Britton W 10-12:30 Is H20 Bad for You? Aim In this lab I will research how moisture affects the mold of bread.
To describe the results, Nature invited analysis from 77 scientists from labs as far away as Scotland and Israel. You could try adding moisture to the slices or putting different amounts of sugar or lemon juice onto the slices. This was the first time during the experiment that the bags were opened. Penicillium, Cladosporium and black bread mold are three common bread molds. Also, after you are done noting down the results of the experiment, dispose off the bags containing moldy bread safely, without opening them.
