Bacterial Growth

good luck none Biology II 1996 The Effects of Antibiotics on Bacterial Growth         Bacteria nuclear number 18 the roughly common and ancient microorganisms on earth. Most bacterium atomic number 18 microscopic, measuring 1 micrometer in length. However, colonies of bacterium bad in a testing ground petri dish evict be seen with the unaided eye.         There atomic number 18 more divisions and classifications of bacterium that assist in identifying them. The first two types of bacterium be archae bacterium and eubacteria. two separates have common ancestors dating to more than than 3 million years ago. Archaebacteria part in environments where, beca habit of the high temperature, no former(a) life can grow. These environments span hot springs and atomic number 18as of volcanic activity. They take lipids but lack creditworthy chemicals in their cell wall. eubacterium are all different bacteria. Most of them are phototrophic, i.e. they commit the suns energy as nourishment through the process of photosynthesis.          other classification of bacteria is burst to their need of oxygen to prevail. Those who do require oxygen to live are considered aerobes. The bacteria who dont use oxygen to live are know as anaerobes.         The clear to pass of specific bacteria provides for the coterminous step in the identification process.

Spherical bacteria are called cocci; the bacteria that have a baculiform shape are known as bacilli; corkscrew molded bacteria are spirilla; and filamentous is the term for bacteria with a threadlike appearance.         Hans Christian Joachim Gram, a Danish microbiologist, essential a method for distinguishing bacteria by their different chemical reaction to a besmirch. The process of applying Grams stain is as follows: the bacteria are stained with a empurpled tinge and treated with Grams rootage (1 take off iodine, 2 parts potassium iodide, and ccc parts water). ethyl group alcohol is then use to the medium; the bacteria will either preserve the robust color of the original sully or they...
