In biology 102 lab‚ I conducted an experiment dealing with worms and how they regenerate or “grow”. We did this study over a specific type of worm called Planaria‚ which are simple‚ small‚ flat worms that reside in aquatic environments and are free-living (Brewton‚ 2017‚ p. 44). To start‚ I went over to the lab counters and obtained my worm with a plastic pipette‚ sucking up the worm with a little bit of water and placing it in a tiny covered plate. The water was essential to include with the worm

are acidic dyes since they do not cross the cell wall/membrane particularly easily. A background stain is a stain used to stain everything other than the bacteria. The Gram stain is one of the oldest‚ most cost-efficient‚ yet most under-utilized‚ staining method used to identify bacteria. It consists of a basic dye (the primary stain crystal violet)‚ a mordant (Gram ’s iodine)‚ decolorizer (acetone:alcohol) and a counter stain (safranin). A mordant is a compound which helps hold the primary stain

morphologies were then observed and recorded‚ unknown A and unknown B‚ a Gram stain was then performed for each unknown. After determining the Gram reaction‚ alternate staining procedures were performed as needed. Unknown A required further endospore staining‚ whereas unknown B required no further staining procedures. Once all staining methods were complete‚ specific biochemical tests were performed. The biochemical tests were chosen from the unknown identification tables and dichotomous keys that

How will a microbiologist use this staining method to begin the identification of bacteria? Microbiologists use this staining method to begin the identification of bacteria because it will allow them to tell the four different categories based upon color reaction and shape. It is the first step that will help in identifying bacteria

The Identification of Bacillus Badius [pic] Hannah Melanchuk Dr. Robert Suran May 1 2013 Microbiology Abstract Over a three week time span I was able to successfully identify an unknown microorganism by combining the results of several tests. The first test was the Gram stain test which showed the microorganism was Gram positive and rod shaped. Using an Unknown Identification Flowchart‚ I proceeded to inoculate a Starch plate. In week 2‚ I

thick peptidoglycan layer. This wall forms in a mesh like formation of three layers of alternating material. 2. From the procedure that you have carried out‚do you feel that the Gram positive stain is a simple procedure? No‚ because there are many procedure to do and more complex than simple ones and use more than one stain to differentiate cellular components. Discussion The Gram stain procedure uses 3 different stains. These are crystal violet‚ Gram’s iodine‚ and safranin. The cells are

Section 4 Biol 311 Staining and Identifying Unknown Bacteria Introduction: The microbiology lab up to this point has been used to teach the students how to stain and identify bacteria. There are several types of staining through which the bacteria can be identified based on the color and shape. The staining methods used in the lab are Gram Staining‚ Capsule Staining‚ Endospore Staining‚ and Acid Fast staining. One of the most significant method of staining is the Gram Staining‚ as it is highly dependent

1 1. Explain the principle of positive staining. (3 marks) Positive staining is done by staining the cell walls of Gram-positive bacteria with crystal violet. The cell wall of Gram-positive bacteria is made up of a thick layer of peptidoglycan which undergoes dehydration during decolourisation causing the pores to shrink. This shrinkage of pores traps CV-I complex and stain the cell purple. 2. Using a flow chart‚ outline the process of gram staining. (5 marks) Flood the slide with crystal
