To fully understand this lab we first need to know what gram-negative and gram-positive bacteria are and what it’s composed of. Gram-positive bacteria take up the class of bacteria that stain crystal violet in the method of bacterial differentiation. Where gram-negative bacteria are a class of bacteria that does not retain crystal violet. Instead they are counter-stained pink by Safranin‚ and because of this‚ identifying positive is possible. One of the many differences between gram-negative and

Gram Stain: Gram is an empirical method to distinguish the species of bacteria into two groups Gram-positive and Gram-negative based on the physicochemical properties of the cells. First‚ a smear was prepared by use a sterile transfer loop that been flamed to removes some bacteria from slant agar and placed on the slide; mixed with one drop of water and let air dried. After dried‚ heat fixation the slide by passed the slide over a flame quickly 2-3 times to stick bacteria to the slide. Next‚ the

In the unknown identification labs‚ we have identified our unknown as Pseudomonas aeruginosa. Pseudomonas aeruginosa is Gram negative and rod shaped that we found to be motile in the lab. Our strain of P. aeruginosa formed colonies that were round in shape and had scalloped margins on nutrient agar. On our agar slant‚ the P. aeruginosa colonies had a filiform appearance on the edges. I think we correctly identified our unknown as P. aeruginosa because we performed several different tests‚ eleven

Bacteria Morphology April 2‚ 2015 Abstract – The Purpose of this exercise is to gain experience in bacterial morphologies in prepared wet-mounted slides and interpreting the findings of bacteria through direct and indirect staining technique. Hypothesis – The experiment will allow for further insight into stained organisms‚ allowing extended contrast‚ differentiating shape and structure through utilization of microscope. Procedure – Instructions followed as per procedure‚ specimens

Simple Pendulum Experiment In this experiment you will make a simple pendulum consisting of a plumb bob and a piece of string anchored at two points. By attaching the string to two points the normal precession that would occur will be eliminated.
