The purpose of this report is to explain the process and steps used to identify a certain microorganism referred to as the unknown. Materials and Methods A test tube with an unknown microorganism will be retrieved. Once the test tube is retrieved‚ a steak for isolation will be completed in order to produce isolated colonies of the organism on an agar plate. The unknown test tube with the bacteria is flame sterilized using a Bunsen burner. Once the bacterium test tube has been flame sterilized

or clusters and form distinct colonies. Bacteria are classified on the basis of many characteristics. Morphological and physiological features such as cell shape‚ motility‚ formation of spores and other distinguishable structures‚ and reaction to Gram stain is a good start in identifying bacteria. Other staining techniques such as Acid Fast stain are also useful in determining species. More important in identification of a genus and species of bacteria are biological tests‚ including the determination

Gram Stain: The important part of this experiment is being able to determine a bacterium based on its cell wall structure. It also helps indentify if the unknown organism is a Gram positive or Gram negative. This is the initial step that must be taken before any other lab procedure may continue on to ensure the purity is present‚ the arrangement of the cells‚ and the shape the cell has. The staining of the cell starts off with using the primary stain‚ Crystal Violet which is a purple color‚ to begin

Gram Staining Introduction Prokaryotes are a large group of organisms with no membrane bound organelles. They consist of two domains: Archaea and Bacteria. These organisms are only found in extreme environments such as volcanoes. Prokaryotes are still being researched and are a very diverse group. In this lab we focused on trying to identify if the bacteria found had a lot of peptidoglycan by gram staining. Testing this could be done by using a Petri dish full of agar and testing different bacteria

Introduction:The objective throughout the gram staining experiment was to classify bacteria through their chemical nature as well as the physical structure of their cell walls. Through this experiment one would be able to observe either a thick or thin layer of peptidoglycan by the appearance of the bacteria staining either gram-positive blue-purple or gram-negative pink. Question: Is there a subsequent effect of the bacteria when decolorizing with alcohol? Hypothesis: If there is either a removal

Asset bubbles are some of the worst types of recessions because they take the longest to unwind. The next couple of years will go much like this…. - US Dollar will give a short-term rally in the next 6 months only to continue its long term devaluation. It will include an approximate 50% decline (currently at 37%) by the end of the decade in relation to its 2001 levels. - All commodities (including gas) will continue to rise at around 5% to 7% on average as inflation continues to accelerate
