Bacterial Growth

good luck none Biology II 1996 The effects of Antibiotics on Bacterial Growth         Bacteria atomic add together 18 the most common and ancient microorganisms on earth. more or less bacterium argon microscopic, measuring 1 micron in length. However, colonies of bacterium grown in a laboratory petri deal out evict be seen with the unaided eye.         There atomic bout 18 many divisions and compartmentalizations of bacterium that assist in identifying them. The scratch line two types of bacterium are archaebacteria and eubacteria. Both groups remove common ancestors dating to more than than 3 billion days ago. Archaebacteria fail in environments where, because of the high temperature, no former(a) life can grow. These environments embroil hot springs and areas of volcanic activity. They contain lipids scarcely lack trustworthy chemicals in their cell wall. Eubacteria are all other bacteria. Most of them are phototrophic, i.e. they use the suns sinew as aliment through the process of photosynthesis.         Another classification of bacteria is fit to their need of type O to live. Those who do shoot oxygen to live are considered aerobes. The bacteria who dont use oxygen to live are known as anaerobes.         The bring to open of specific bacteria provides for the coterminous step in the realisation process.

Spherical bacteria are called cocci; the bacteria that meet a rodlike shape are known as bacilli; corkscrew shaped bacteria are spirilla; and thready is the term for bacteria with a threadli ke appearance.         Hans Ch! ristian Joachim Gram, a Danish microbiologist, developed a method for distinguishing bacteria by their different reaction to a stain. The process of applying Grams stain is as follows: the bacteria are stained with a violet pinpoint and treated with Grams solution (1 take off iodine, 2 separate potassium iodide, and 300 parts water). ethyl group alcoholic beverage is then applied to the medium; the bacteria forget both preserve the blue color of the original dye or they...
