Microorganisms are both beneficial and harmful. These microorganisms are important to humans because they play a role in the ecology of life, by decomposing wastes, both natural and man-made, such as creating nitrogen fertilizer at the root zones of certain crops. Other several pathogens that can cause serious harm, even immediate death due to the diseases or disease causing products they produce. Overall, microorganisms play an important role in life.
The article “Some of My Best Friends are Germs,” by Michael Pollen was a very interesting and informative read. Pollen explains that our bodies house 100s of trillions of microbes. More than 99 percent of our genetic information is microbial. The large number of bacteria that inhabits us weighs many pounds, forming a massive, unexplored world that scientists are just starting to document. These bacteria affect our health as much as if not more than the genes we receive from our parents.
Bacterial and fungi infections are easy to cure with the use of antibiotics, where as viruses can be hard to cure or vaccinate against, such as the common cold. Bacteria can be found everywhere and anywhere Soil, Water, Plants, Animals, material and even deep in the earth's crust. Bacteria feed themselves by making there food with the use of sunlight and water. We would not be able to live without Bacteria. The human body consists of lots of friendly bacteria which also protect us from dangerous ones by occupying places in the body. Some of the most deadly diseases and devastating epidemics in human history have
Microbes are necessary for life to exist. "Without microbes, decomposition cannot take place" (Chivukula, 2015). Photosynthesis and decomposition are vital to the ecosystem to ensure that life can exist, and both use microbial activity to provide energy and nutrients. Photosynthesis must take place to convert light into chemical energy for organic material. Decomposition uses microbial activity to breakdown
Vast numbers and kinds of organisms, mainly microorganisms, inhabit soil and depend on it for shelter, food, and water. Plants anchor themselves in soil, and from it they receive essential minerals and water. Terrestrial plants could not survive without soil, and because we depend on plants for our food, humans could not exist without soil either (Wiley, 2013).
Microbes are bacteria, archaea and eukaryotes. The earth was formed 4.6 million years ago. And a few million years later, by 3.5 billion years ago, earth was already inhabited by a diversity of organisms. The earliest organism is Prokaryotes and within the next billion years, two distinct groups of prokaryotes called bacteria and archaea diverged. Eukaryotes cell evolved from a prokaryotes community, a host cell containing even smaller prokaryotes .The microbial world accounted for all known life forms for nearly 50 to 90% of Earth's history. We are still researching microbial organisms today in marine environment, extreme environments. A microbial observatory is an NSF-funded project dedicated to the discovery and characterization of novel microorganisms and microbial communities of diverse
Before, biologists assumed all microbes are bad for the human body (automatically thought of pathogens), caused many diseases and harm our body fundamental systems. In addition, the biologists think that our body is already built which had all the functions required to maintain our health. However, the attitude has changed over the last decade. The biologists characterized the most prevalent species of microbes in the body, and found out that these collective microbes do not threaten us, and they also are important part of human bodies.
The microbes found in soil go hand in hand with the microbes found in our bodies, especially the gut microbiome. Soil is used to grow various plants and crops which we then ingest. As stated in Healthy Soil Microbes, Healthy People, we have completely destroyed soil microbes by overusing fertilizers and pesticides just like how we have destroyed our gut microbes by ingesting processed foods and large amounts of antibiotics. Soil microbes, including bacteria and fungi, form symbiotic relationships with plant roots to help provide the plant with many nutrients needed to survive. In order to restore and improve the soil once again, we need to reintroduce bacteria and fungi that are capable of repairing the damage. Through recent technological advances, the soil microbiome was genetically sequenced. This allows farmers and other scientists to understand which microorganisms are
This research paper is a primary research paper because the paper indicates that a study was done by several biologist and scientist on the microbial community in the Rhizosphere. Therefore, all the research, answers, and conclusion they all concluded based on their study was explained throughout this paper based on all the information they gathered. Also, the authors explain the process and methods they used to carry out and conduct this research on the microbial communities. I came down to this conclusion by understanding what they wrote is backed up by evidence by explaining the procedure they carried out to study these microbial communities.
Microbes aren’t really mentioned much today, but back when the New World was discovered, these Microbes were causing a lot of trouble in the Old and New World. So let’s go back to 1494. In Europe, a very dangerous disease known as Syphilis came about. This disease was most likely coming from sexual transmission and even killed children once born. In the New World, we assume that everyone was healthy, but there are signs that Syphilis was already there. We don’t know if that’s true, but that evidence is still there in case the claim is fact. Then by the time Columbus arrived, his team spread the smallpox disease to the Native Americans.To make things worse, Cortes came in and starved all the Aztecs and the city was destroyed in seventy five
In this search for new hells to dwell in, an international team of researchers drilled over 2400 meters down off the coast of northeast Japan. Co-author Kai-Uwe Hinrichs, a biogeochemist at the University of Bremen in Germany mentioned that roughly 23 million years ago this place was actually coastal, sporting the sort of low lagoons and wetlands that we still enjoy in present Florida. However, he added that this area gradually sank due to continental drift, and eventually became covered by sediment. These days these layers are smothered in coal.
Microorganisms senses and respond to changes in environment. Certain types of Gram-positive bacteria species such as certain Bacillus and Clostridium species forms endospores when encountering environmental stress such as nutrient starvation  as shown in Fig 27. The bacterial spores differ significantly from the corresponding vegetative cells. Spores are metabolically dormant and exhibit resistance properties making them highly resistant to many treatments including extremes of temperature, radiation and chemical biocides . The extraordinary resistance properties of endospores make them of particular importance because they are not easily killed by common biocidal agents.
