At the beginning of the semester‚ samples of bacteria were obtained from various sources. Two bacterial colonies were isolated from plates that were incubated in the lab and these bacteria became the basis for this project. The bacterial cultures were maintained and used for various physiological‚ cultural‚ and biochemical tests and observations over several weeks. The purpose of culturing bacteria over half the course of the semester was to learn various techniques used in microbiology labs and

It is thought that archaea and bacteria were diverged early in their existence because of all the dissimilarities between the two groups. Both bacteria and archaea are enclosed in cell membranes. Archaea have a single cell membrane that absences a peptidoglycan wall and also their genetic transcription and translation‚ the two main processes in molecular biology do not show the typical bacterial features‚ but are quite similar to those of eukaryotes. Archaea are more related to eukaryotes‚ even though

What is Food Microbiology Food microbiology is the study of food micro-organisms; how we can identify and culture them‚ how they live‚ how some infect and cause disease and how we can make use of their activities. Microbes are single-cell organisms so tiny that millions can fit into the eye of a needle. They are the oldest form of life on earth. Microbe fossils date back more than 3.5 billion years to a time when the Earth was covered with oceans that regularly reached the boiling point‚ hundreds

to those presently found on earth Archaea are single cell micro-organisms with no nucleus‚ it use anaerobic respiration (able to living in the absence of Oxygen) and live in extreme environment/condition such as high temperature‚ acid-rich‚ saline area etc. those environment are rich in minerals but hazardous to other organisms. Archaea’s population decreased after earth filled with oxygen‚ other than that‚ current archaea is very same as ancient archaea. Archaea like to live near Black Smoker (volcanoes

History of microorganisms’ discovery Anton van Leeuwenhoek was the one of the first people to observe microorganisms‚ and used a microscope of his own design‚ and made one of the most important contributions to biology. [18] Robert Hooke was the first to use a microscope to observe living things; his 1665 book Micrographia contained descriptions of plant cells. Before Leeuwenhoek’s discovery of microorganisms in 1675‚ it had been a mystery why grapes could be turned into wine‚ milk into cheese
Premium Bacteria Eukaryote Cell
The prokaryotic cell precedes any forms of Bacteria‚ Archaea‚ and eventually Eukaryotes by approximately two billion years. This cell was the original life form on the planet and represents the smallest and least complex of all organisms. Through the process of mutation and adaptation they were able to survive to evolve into our modern day Bacteria‚ Archaea‚ Fungi and Protists. These post organisms have benefited from their early ancestor‚ by way of Endosymbiosis. Intricate protest and fungi are

Evolutionary biologist‚ William Martin‚ tried to determine the Last universal Common ancestor or LUCA. Given that bacteria and archaea are thought to be the earliest domains‚ Martin and his team classified the known protein-coding genes of both archaea and bacteria. They examined the sequence of the genes to determine the ancestral gene‚ of which the particular genes came from. From this process‚ they narrowed down the genes from about six million to three hundred thirty five genes that were likely
