Measuring the Growth Rate of Mold in Different Exposures and Temperatures

SMC 1312 Foundation of Reflection: Nature F

Abstract The purpose of this experiment was to determine whether different exposures and temperatures affect the growth rate of mold in rice. We tested six different treatments of rice for a period of five weeks that were, refrigerated open, closed and open for observation, and unrefrigerated open, closed and open for observation. The results showed that the growth rate of the unrefrigerated treatments was much higher than those treatments that were in a fridge. Also, the treatments that help maintain the moisture, also showed to have a greater affect on the growth rate of mold. It was concluded that mold needs the right temperature to grow in; however, it also needs the right amount of moisture to maintain its self and continue to grow.

Introduction In this experiment, it was tested which environmental condition stimulated the most growth in mold. There were six conditions that were being tested: refrigerated open, closed, and open for observation and unrefrigerated open, closed, and open for observation. The dependent variable was the growth rate of mold. The independent variable is the rice in the different conditions.
It was hypothesized that the unrefrigerated open was going to develop the most mold because it was exposed to spores all the time. It was also hypothesized that the refrigerated rice was not going to grow any mold due to the refrigerator.
It was concluded that the mold only tends to grow in unrefrigerated areas, where there is moisture available.
Rice is a huge food source for humans, and accounts for one fifth of the total calories consumed. It is second (after corn) on world food production, proving that rice is a huge part of humans diet. Rice also requires a lot of water for it to grow; however, it can grow almost everywhere. This is an ideal condition for mold. Mold only

    This experiment is to observe the significance of food safety. In addition, it will illustrate foodborne sicknesses and how food can be compromised by bacteria. This lab will culture washed and unwashed lettuce, as well as fresh unopened milk, and milk that has been opened for 7 days. The prediction for this lab, is that the unwashed lettuce and the opened milk will have the most bacteria growth. All results are meticulous within the expectations of the lab report.…

    Bacteria growth is known to be either augmented or impeded by a number of various factors; in this experiment, our group tested how E. coli is affected by penicillin as well as how different temperatures can affect bacteria growth. We know that antibiotics are generally specialized against certain types of bacteria—more specifically, some are most effective against Gram-negative, some against Gram-positive, and some are more broad spectrum. Given that E. coli is known to be a Gram-negative bacteria, our hypothesis was that Penicillin (narrow Gram-positive spectrum) would not be effective against E. coli; we also hypothesized that increasing temperature in the environment of the bacteria would be directly increase overall growth. We tested these hypotheses by preparing five different petri dishes, each containing cultures of the bacteria E. coli. In two of these dishes (set up identically), containing plain agar with no additional nutrients, we added small amounts of Penicillin to half the plate and water to the other half. We then observed the plates after one week’s time. For the other three plates we stored one dish at 4°C, one at 22°C, and one at 37°C; no antibiotics were added to any of these three dishes. Lastly, we then compared bacterial growth in the dishes that had been stored at different temperatures. Our final results indicated that Penicillin is not effective against E. coli because it is a narrow Gram-positive antibiotic that works by inhibiting an enzyme required for bacterial cell wall formation but some E. coli produces a slightly different version of the enzyme so reproduction may be slowed but will not stop. The other aspect of our hypothesis that temperature affects growth was found to be true as demonstrated by the plates stored at higher temperatures exhibiting substantially more growth. Determining the exact nature and…

    aflatoxin

    Aflatoxin is a naturally occurring mycotoxin produced by three types of mold: Aspergillus flavus, Aspergillus parasiticus, and Asperilligus nomius (more rare). Aspergillus flavus is common and widespread in nature and is most often found when certain grains are grown under stressful conditions such as drought. The mold occurs in soil, decaying vegetation, hay, and grains undergoing microbiological deterioration and invades all types of organic substrates whenever and wherever the conditions are favorable for its growth. Favorable conditions include high moisture content and high temperature, though growth can occur at quite low moisture levels and a broad range of temperature (13-37 degrees Celcius). At least 13 different types of aflatoxin are produced in nature with aflatoxin B1 considered as the most toxic. While the presence of Aspergillus flavus does not always indicate harmful levels of aflatoxin it does mean that the potential for aflatoxin production is present.…
