Unknown Lab Report April 25th‚ 2006 Introduction The purpose of this lab was to identify two unknown bacteria cultures using various differential tests. The identification of these unknown cultures was accomplished by separating and differentiating possible bacteria based on specific biochemical characteristics. Whether the tests performed identified specific enzymatic reactions or metabolic pathways‚ each was used in a way to help recognize those specifics and identify the unknown cultures

Organic Chemistry II Lab 9 Fermentation of a Carbohydrate: Ethanol from Sucrose * Introduction Ethanol is one of the oldest alcohols and also the least toxic one. Industrially‚ ethanol is made most economically by hydration of ethylene. However‚ ethanol that is intended for human consumption must‚ by law‚ be prepared by fermentation. By either method‚ ethanol‚ of course‚ has the same formula‚ structure‚ and properties. The fermentation takes place with the assistance of enzymes from yeast

reproductive. Orientation is when the organism is placed in their beneficial environment consisting of two behaviors‚ taxis (movement directly towards or away something) and kinesis (random movement). Reproductive is detected using drosophila in this lab‚ it consists of finding courting and mating with another of the species Agnostic behavior is found in a situation where the animal feels threated by another‚ leading to the organism looking bigger or more threatening to the opponent. Within the Agnostic

Carbohydrate Lab Report Introduction Qualitative identification of a substance is of significant importance in chemistry. Physical constants such as melting points have traditionally been used by organic chemistry for identification of unknown compounds. As for inorganic substances‚ the precipitation of a solid‚ results of a flame test‚ or the formation of a colored substance could all be keys to identifying a sample. Chromatography and spectra are amongst the newer techniques
