Key Events Of Microbiology

There were three significant events that happen at the beginning of microbiology period. The first event was the discovery of cells. A scientist name Robert Hooke was the first one to watch cells when he looked into a thin slice of cork, which we now use for closing wine, through a microscope that wasn’t as powerful but allowed him to see cells. Hooke then made a better microscope that had two sets of lenses which allowed him to see individual cells. His discovery started the beginning of the Cell Theory, which says that everything is made of cells. Since Hooke’s findings we have been able to keep studying diseases based on looking at cells, and since then new microscopes have been invented to continue to study new cells, bacteria viruses, …show more content…
He then found microorganism in the one that was left open. He then prove that microorganism can be in solids, liquids and in the air. When doing his experiments he also discovered that microorganism can be destroy by heat. If it wasn’t for his findings people would still think that microorganism arise from mud or from a chair. People would have been worry about what creature would arise from their stuff. We still used the biogenesis theory for example when a fruit starts to have small flies around it, we know that does flies didn’t arise from the fruit but instead those actually may come from other flies that may be near your home and that are able to go inside peoples house through window screens because they are very small. Pasteurization was also a great discovery that happen 1864 and it was found it also by Louis Pasteur. This happen when a merchant asked Pasteur to find out why beer and wine spoil too fast. He then found out that beer and wine had bacteria and he knew that heating it could actually kill it. He did this and this was what came to be known as Pasteurization. Since the discovery of this we have still use this method to make beer, wine, milk and other things last …show more content…
Prokaryotic cells include bacteria that includes pathogenic and nonpathogenic prokaryotes that can be found in soil or water. The six types of bacteria include Proteobacteria, they are gram negative and are the largest classification of all of the bacterias. Proteobacteria has five classes which are alpha, beta, gamma and delta. The next classification is Cyanobacterias which has some oxygenic photosynthetic bacteria. All of them are gram negative and they like to live different environment. Chlamydidas is another classification of bacteria which is also gram negative and they only tend to grow inside another cell. Firmicutes low is another classification which is gram positive and some of this bacterias don’t have a cell wall. Some types of Firmicutes bacteria include Lactobacillales bacteria which cause tooth decay and it can also grow in the fridge. Actinobateria is also a gram positive bacteria that include actimomyces bacteria that we can use to make antibiotics. The last classification of bacteria is Spirochetes which is shape like a spring and it also doesn’t have peptidoglycan. Another type of a prokaryote cell is Archaea which doesn’t really cause human diseases. This type of prokaryote doesn’t have peptidoglycan in their cell wall. They can come in different shapes and they can survive in extreme environments. Prokaryotes have two types
