Similarities Between Yeast And Yeast

Improved Essays
Molds are multi- or unicellular while yeasts are unicellular in structure.
Molds grow in the form of tangled mass called the mycelium which is composed of filamentous hyphae while yeasts are spherical or oval-shaped.
Molds are colourful while yeast are colourless.
Molds can reproduce through small spores sexually or asexually while yeast reproduce asexually by budding or binary fission through mitosis in which a nucleus is divided into two or more nuclei.
Mould can grow on food with low pH and low water activities that would normally inhibit growth of yeast which will cause a greater risk in terms of food spoilage and are harmful to our health although there are some molds that help in food production for example mold ripened cheeses. But, yeasts are generally harmless and crucial in food

Enzymes are naturally occurring proteins which are exist in all food. They catalyse chemical reaction by breaking down the food components by oxidation, browning and ripening that result in changes of flavour, colour and texture and lead to food spoilage. Apart from that, most of the fats and oils do not store properly, they develop off flavours and odours known as rancidity and sometimes toxic substances are formed. The presence of moisture, oxygen and light are among the factors that speed up rancidity.

Food poisoning can be caused by eating food contaminated with bacteria such as campylobacter, salmonella, listeria, shigella and Clostridium perfringens. With moisture, a food source, enough time, and suitable temperatures, bacteria will grow and multiply rapidly on foods, especially related to improper foods handling. Food which has become contaminated with harmful bacteria does not always taste bad but it looks, smells and tastes like it normally does. The symptoms may include, nausea, vomiting, stomach pains, diarrhoea, feeling weak, fever or chills/sweating and

    Purpose and Background Cells divide in two ways, mitosis and meiosis. Mitosis is used to produce cells that are genetically identical to the parent cell for growth, asexual reproduction, or repair after injury. Cells that are produced by mitosis are diploid, meaning that they have two complete sets of chromosomes, one from each parent. Meiosis is used to produce haploid cells that have only one set of chromosomes, a mix of chromosomes from both parents. Meiosis produces cells that are genetically unique from their parent cells.…

    In the four-week long experiment conducted in the Bio 13 Lab, we were able to conduct a genetic analysis of the yeast S. cerevisiae, particularly investigating the inheritance and linkage of three genes: HIS4, LEU2, and LYS2. In week one, a suspension of spores was received and aliquots of the suspension were plates onto two YPD plates. After a week of yeast growth, haploid spore clones were carefully picked from the plates by sterile toothpicks and used to make patches on a new YPD plate, the master plate. In week three, the master plate was replicated onto three dropout plates: -His, -Leu, and -Lys. In the final week, the growth of the patches on the dropout plates were analyzed and class data was collected in order to conduct calculations for…

    Mold is fungi that are found outdoors and inside homes. Molds grows exceptionally well on paper products and in moist dark environments. Nevertheless, mold is found in every environment, including dry conditions and reproduce year round. Areas in which mold are found include greenhouses, saunas, farms, mills, construction areas, basements and showers. According to the Center of Disease Control (CDC) mold thrives on three conditions.…

    When Marty went to Earth to find life in his head he used the acronym CAR-ME-GO. The acronym we teach all Martians that we plan on sending to Earth to decide if an object is living or not. Keeping this in mind as we go through the acronym we will see that cars do pass this test and because it pass that means it is alive. The acronym starts with C which stands for control means that a living thing uses energy to maintain an internal state. Cars have control because the use the liquid substances, that Marty noticed, to be able to keep the car going.…

    The CDC had said that contaminated foods get at least 48 million Americans sick annually which led to 128,000 to the hospital and 3,000 people would die from being sick (Newsela). Due to the worrying of food contamination the CDC would create the gene sequence tool that can track down the source of the outbreak much more faster (Newsela). Salmonella symptoms are diarrhea, cramps and fever, but some people may get nausea, chills, and vomiting. These symptoms start to show after 72 hours of consumption of the contaminated food, lasting up to a…

    During this experiment, mold spores were placed on water logged bread, and then put in various temperature to determine which temperature inhibits the growth of decomposer colonies the most. A trend that was that was observed in the experiment was that mold spores did not colonize in the incubator, refrigerator, and freezer. The major finding in this experiment was that mold seems to prosper in room temperature, but does the opposite in colder and warmer environments. The hypothesis, if decomposer colonies are exposed to a variety of temperatures then less will grow in cold temperature, was supported by our data.…

Some examples of protoctista are paramecium, amoeba and unicellular algae. -Prokaryotes: These are also unicellular organisms like protoctista but unlike them, they do not have a nucleus. An example of a Prokaryote is bacteria.…

    It has been proven that yeast can grow on both YPD and SD plates. In this lab we cross several yeast strains through the process called replica plating. For this identification test only one dominant allele is required. One copy of each gene is essential to produce enough of each enzyme needed in order to make a histidine. Through the study of Saccharomyces cerevisiae we prove that by transferring yeast cells onto YPD and SD plates over a period of 24-72 hours in a thirty degrees Celsius incubator, in return will grow yeast.…
