Modern microbiology reaches into many fields of human endeavor, including the development of pharmaceutical products, the use of quality‐control methods in food and dairy product production, the control of disease‐causing microorganisms in consumable waters, and the industrial applications of microorganisms.
Early history of microbiology. Historians are unsure who made the first observations of microorganisms, but the microscope was available during the mid‐1600s, and an English scientist named Robert Hooke made key observations. He is reputed to have observed strands of fungi among the specimens of cells he viewed.
Microorganisms triggered many events that drastically altered human history. The most notorious microbes caused mass death and destruction, but they also inspired modern medical advances often taken for granted. The significant impact these tiny, invisible-to-the-naked-eye creatures can have on our world is astounding.
Some of the diseases caused by microorganisms are listed below:HIV/AIDS.Typhoid.Cholera.Meningitis.Syphilis.Chicken Pox.Malaria.Tuberculosis.More items...
billions of years ago, microbes converted the earth's entire atmosphere from nitrogen-based to oxygen-based, making it possible for larger forms of life to evolve. Human evolution has been inextricably linked with the microbes that have sur- rounded us from the very beginning.
Microbiology came into being largely through studies of bacteria. The experiments of Louis Pasteur in France, Robert Koch in Germany, and others in the late 1800s established the importance of microbes to humans.

For example, each human body hosts 10 microorganisms for every human cell, and these microbes contribute to digestion, produce vitamin K, promote development of the immune system, and detoxify harmful chemicals. And, of course, microbes are essential to making many foods we enjoy, such as bread, cheese, and wine.
1861– Louis Pasteur introduced the terms aerobic and anaerobic in describing the growth of yeast at the expense of sugar in the presence or absence of oxygen. 1876 – Robert Koch's discovery of anthrax bacillus in 1876 launched the field of medical bacteriology. 1884 – Hans Christian J.
Microorganisms have several vital roles in ecosystems: decomposition, oxygen production, evolution, and symbiotic relationships. Decomposition is where dead animal or plant matter is broken down into more basic molecules. This process only happens because of the microorganisms that find their way into the dead matter.
Microorganisms include bacteria, protozoa, algae, and fungi. Although viruses are not considered living organisms, they are sometimes classified as microorganisms.
Answer and Explanation: Microbiology developed as a result of two significant occurrences: The discovery that microbes and bacteria cause diseases revolutionized medicine...
Pasteurization, penicillin, Koch's postulates, and gene coding. These discoveries and inventions are vital yet commonplace in modern life, but were radical when first introduced to the public and academia.
In certain cases, like that of the bubonic plague, population levels were drastically reduced for centuries afterward. In other cases, such as polio, the infection of a renowned individual led to the further recognition of a disease and the need for a cure. Featured image credit: sciencemag.org.
Along with natural disasters, infectious diseases are among the top unintentional causes of human death and suffering the world over. Some diseases have left their mark on the human race, warping the course of human history in their wake. In certain cases, like that of the bubonic plague, population levels were drastically reduced ...
Historians believe that the spread of the bubonic plague contributed to the fall of the feudal economic system and caused irreparable damage to the church. Many priests were infected after performing last rites and funeral services. Still more withdrew from their parishes, afraid of contracting the plague.
The bubonic plague demonstrated early on how human advancements in commerce and trade could fatally spread a pathogen. The plague’s name comes from the Latin word bubo, referring to a pustule or abscess.
There are four stages of syphilis, a sexually transmitted disease that first appears with a benign chancre at the spot of infection. Secondary syphilis presents with a widespread rash and swollen lymph nodes. The bacteria then enters a latent stage before surfacing as tertiary syphilis, which leads to neuromuscular degeneration, blindness, and dementia.
Tuberculosis left its mark on science in more than one way. In the 19th century, TB was often spread through milk. This led to the development of batch pasteurization, a low-temperature method of pasteurization which has its roots in eradicating tuberculosis in dairy products.
But they also brought smallpox, which played an instrumental role in killing Native Americans.
biocleaning, biofuels, bioLogic, bioproducts, oil spill, Pseudomonas. Researchers are continuously discovering the incredible abilities of microorganisms. Below are just six examples of how microorganisms can improve our lives and even cleanup man-made messes. 1.
BP’s 2010 oil spill in the Gulf of Mexico was an extraordinary environmental disaster, but we can thank microorganisms including Colwellia, Cycloclasticus, Oceanospirillales, Alcanovorax and Methylococcaceae for keeping the spill from leaving an even greater impact. Hydrocarbon molecules in natural gas are small and easy to degrade allowing microorganisms to “eat up” much of the gas. A bacterial bloom instigated by ocean currents turned millions of barrels of oil into an estimated 100 sextillion microbial cells.
Fashionable fungi. Incorporating microorganisms could be the next big thing in the clothing industry. An article by Vice highlighted biofabricated textiles made from living microorganisms or cells like genetically modified yeasts and fabrics full of bacteria.
In the human body, different microorganisms are responsible for contributing to different processes, such as digestion and defense of other invasive organisms in a complex process that is reflected in the natural course of a disease . Microorganisms are beneficial in different industries and contribute to multiple biological processes taking place ...
Humans have used microorganisms in different industries, such as food or agriculture, where fermented beer , Yogurt and cheese, or microorganisms can be used to release nitrogen from the soil that plants need to grow. Not all microorganisms are beneficial to human life, there are some organisms that limit the production ...
For this reason, compounds such as probiotics have been developed to administer necessary doses of beneficial bacteria that allow the regulation of internal processes of the body.
The fermentation process leading to the production of alcoholic beverages or acid based dairy products takes place when microorganisms get energy from food cells without having to take oxygen.
The benefits derived from the action of microorganisms take place thanks to their metabolic activities in the medium. Activities they perform in relation to plants and animals, from which they take their energy to carry out biological processes.
They are responsible for cleaning the waste through a biological process of decomposition or stabilization of organic matter. This decomposition process is as old as life on planet Earth.
There are billions of bacteria that inhabit the digestive tract of humans. It is estimated that one kilogram of body weight of each person is composed of bacteria known as microflora. These bacteria are responsible for breaking down food remains that have not been previously processed and digested.
The Origin of Microorganisms. Evidence for the origin of life confirms the biblical account that God supplied the information for complex features when He created each kind. In tracking the emergence of the eukaryotic cell one enters a kind of wonderland where scientific pursuit leads almost to fantasy.
As life continued to evolve, multicellular organisms formed as colonies of cells cooperated for mutual benefit. Exactly how a colony of individuals produced a reproductive method that forms the many different cell types needed is not understood and, therefore, is ignored in textbooks.
Multicellular life flourished in the “prehistoric” oceans, and certain organisms began to use others for food. Eventually, photosynthesis allowed an alternative lifestyle, and fungi and plants appeared. The appearance of sexual reproduction offered another benefit that was exploited by certain organisms.
Eukaryotes appear later in the fossil record. Multicellular organisms evolved many times over 700 million years ago. Fungi evolved from eukaryotes 400 million years ago. Eubacteria and archaebacteria evolved from a common ancestor based on interpretations of molecular evidence.
Archaea have given eukarya their informational genes (genes for transcription, translation, etc.), and eubacteria have given eukarya their operational genes (genes for amino acid biosynthesis, fat biosynthesis, etc.). Rather than an evolutionary “tree” of life, a “ring” of life has been suggested.
According to evolution, once life had spontaneously formed on earth it underwent amazing changes. The exact pattern of these changes is greatly disputed, and molecular evidence is calling the accepted order of bacterial evolution into question.
The more genes you have, the less likely you are to suffer from genetic diseases. This would prevent bad genes from affecting a population rapidly and provide a mechanism for the preservation of favorable traits.
A Brief History of Microbiology. Microbiology has had a long, rich history, initially centered in the causes of infectious diseases but now including practical applications of the science. Many individuals have made significant contributions to the development of microbiology. Early history of microbiology. Historians are unsure who made the first ...
After van Leeuwenhoek died, the study of microbiology did not develop rapidly because microscopes were rare and the interest in microorganisms was not high. In those years, scientists debated the theory of spontaneous generation, which stated that microorganisms arise from lifeless matter such as beef broth.
The procedures used by Koch came to be known as Koch's postulates (Figure ). They provided a set of principles whereby other microorganisms could be related to other diseases. The development of microbiology.
Microorganisms are used to produce vitamins, amino acids, enzymes, and growth supplements. They manufacture many foods, including fermented dairy products (sour cream, yogurt, and buttermilk), as well as other fermented foods such as pickles, sauerkraut, breads, and alcoholic beverages. One of the major areas of applied microbiology is ...
His work also encouraged the belief that microorganisms were in the air and could cause disease.
There emerged a Golden Age of Microbiology during which many agents of different infectious diseases were identified. Many of the etiologic agents of microbial disease were discovered during that period, leading to the ability to halt epidemics by interrupting the spread of microorganisms.
With the development of vaccines in the 1950s and 1960s, such viral diseases as polio, measles, mumps, and rubella came under control. Modern microbiology. Modern microbiology reaches into many fields of human endeavor, including the development of pharmaceutical products, the use of quality‐control methods in food and dairy product production, ...
