They play a role in decomposition because after feeding on decomposing plants, they return the organic material to the soil so it can be further digested into nutrients for growing plants. They are also able to remove toxic…
“How mold grows” 10th grade Mr.Tripp Sanders February 3rd, 2018 Purpose The goal of my project is to show everyone how mold grows. Mold grows everywhere. You have probably seen mold a lot. You have seen it mostly on bread and in drinks that have set a long time.…
Mushrooms have DNA and cells that make them what they are. They also show growth and development over a period of observation. They are organized on the sub-cellular level and reproduce given the right environment. Mushrooms adapt, use energy to grow, and respond to stimulus. Sliding Mineral objects (non-living) -…
The objective of this project was to study the diversity on maple tree leaves with location as a variable. This was focused on how locations could influence microbial diversity in the same species of maple tree. Samples from three locations (figure 1 and 2) were obtained and analyzed. The experiment was divided into two major parts: culture dependent and culture independent analyses.…
Sulfanilamide was discovered by an German biochemist. In 1932 he tested red die with a slightly changed chemical makeup and he found that is was effective. He then tried it on his daughter who was dying from a streptococcal infection and noticed she had major improvements and made a full recovery. However penicillin was discovered in a much more different way. Bacteriologist Alexander Fleming discovered germ-killing properties in a secret “mold juice” secreted by penicillium.…
There are three different mutations that have antibiotic resistant genes. Bacterial Conjugation is the direct transfer of DNA from one bacterial cell to another. The transferred DNA is a plasmid, a circle of DNA that is distinct from the main bacterial chromosome. One strand of the plasmid is transferred and the other stays in the original cell. Bacterial Transformation has the transfer of “naked” DNA into a recipient cell.…
They also discovered novel forms of bacteria and fungi; specifically, pithomyces fungi which produces a compound that “binds to a receptor that causes migraines and could block headaches”. Another type of fungi that she found a strain of penicillium fungi which inhibits the growth of lung cancer cells. (“Dirty old mine has rich seam of drugs”, 2006). The discovery of possible pharmaceuticals to treat lung cancers was an unforeseen positive usage that comes with all the negative aspects of the Berkeley…
SOURCE-BASED ESSAY To what extent did the discovery of Penicillin in 1928 affect people and soldiers in World War II in 1945? The discovery of penicillin affected people and soldiers positively in World War II in 1948 to a greater extent as it is seen as the greatest accomplishment in medicine history because it saved thousands of lives during a time of need in World War II. Alexander Fleming is known for the discovery of penicillin.…
As the American populous swayed with the beat of the Big Band era, so did pharmacology sway into action with the upbeat tone of the dawning antibiotic era. Antibiotics are medicine, such as penicillin or its derivatives, that inhibits the growth of or destroys microorganisms. The discovery and development of new antibiotics in the 40’s changed the way people lived by advancing the way infections and diseases were treated, the way live stock was grown, and the improvement of the quality of life in the United States. Sir Alexander Fleming, was a biologist, pharmacologist and botanist, he is known for the discovery of the antibiotic substance benzylpenicillin, Penicillin, from the mould Penicillium notatum in 1928. Penicillin is an antibiotic or group of antibiotics produced naturally by certain blue molds, and now usually prepared synthetically.…
Snails play an important role in the forest decomposition process and they also contribute to soil nutrification through their decaying bodies, shells and faeces. Their dead shells can form a source of calcium for other animals in habitats that don't have a lot of calcium. Snails recycle forest nutrients and are prey for a lot of vertebrate animals and other invertebrates. Their preference for fungi can also be a factor in fungal spore dispersal.…
Penicillin was researched so much in its industrialization period that several strands were developed. The 1945 production of Penicillin was about 20 times stronger than the 1939 version. The Allied Forces benefited greatly from the mass production of Penicillin.…
Bacteria A person with a cold can spread the infection by coughing and/or sneezing. Bacteria or viruses can be passed on by touching or shaking hands with another person. Touching food with dirty hands will also allow viruses or bacteria from the intestine to spread. Water bacteria needs water to dissolve the food they use for energy and growth.…
So why are these fungi important to us today? Looking at the California drought heading to the third consecutive year, many farmers from California is facing problems due to lack of water. A recent report from the federal department of Agriculture states that 20 percent decline in California crops and a 35 percent decline in cotton this year. This is not only concerning for the farmers, but as well consumers as there has been a 3 percent increase in fruit cost, and 2 percent increase in vegetables. Greater demands on water with booming population and decline of water use for farmers caused by environmental laws has created even more problems, and increased research on how we can create crops with less water use.…
His discovery was pure luck. While growing staphylococci bacteria he discovered a mold sample contaminating one of the plates. He observed that the bacteria would not grow near the mold sample18. He established that specific strains of mold could inhibit growth and create antibacterial substances.19 It took ten years and the…
MYCORRHIZAE AND FORESTRY What is Mycorrhiza: Albert Bernard Frank (1885), in his study of relationships between soil microbes and plants, introduced the Greek term ‘mycorrhiza’, which means ‘fungus roots’. Mycorrhizas are highly evolved symbiotic association between roots of most higher/vascular plants and certain specialized soil fungi (Ascomycetes, Basidiomycetes and Zygomyectes) that colonize the root cortex during periods of active plant growth both in the natural environment and in cultivation. This is a non-pathogenic peaceful relationship because on one side fungus provides nourishment to the plant and on the other side, it obtains the necessary carbohydrates and energy from the host plant. Types of Mycorrhizae :…
