Pasteur was the first to propose that microbes cause chemical changes as they grow. Koch derived a central principle of modern microbiology, known as Koch’s Postulate, that determines whether a particular germ causes a given disease. Pasteur and his contemporaries developed pure culture methods for the growth of microbes. By diluting mixtures of microbes in sterile solutions, they were able to obtain droplets that contained a single microbe, which could then be grown on fresh, sterile media. In a separate procedure, they used rapid, sequential passage of cultures so that certain specimens were able to outgrow others.
He first became a haberdasher (a dealer in men’s clothing and accessories) and draper (a dealer in cloth or clothing and dry goods) and, in 1660, chamberlain to the sheriffs at Delft. His hobby was lens grinding. In his lifetime he ground about 400 lenses, most of which were quite small, with a magnifying power of from 50 to 300 times. It was not only his lenses that made him world famous but also his work with the microscope. His keen powers of observation led to discoveries of major significance.
The bacterial cell wall is composed mostly of peptidoglycan, which is made up of polysaccharides and amino acids. The cell walls of the diatom (a tiny one-celled organism) have a high concentration of silica, which gives them a glasslike appearance. Cytoplasm Water is the largest component of cytoplasm. Depending on the cell and its needs and conditions, water concentration varies from about 65 percent to roughly 95 percent. Suspended in the water are various solids such as proteins, carbohydrates, fat droplets, and pigments.
