Next we covered the stain with Gram's Iodine solution and allowed it to sit for one minute. The cells were much easier to see with more detail. There is also such thing as bacteria sex.
Why is it necessary to ensure that your specimens are completely air dried prior to heat fixing? Some potential error in our experiment was not considering the possibility that the light switch had just been cleaned. We removed the excess iodine from the slide and rinsed it in each of the beakers of fresh water.
A nucleus was visible in each cell. We used proper aseptic technique and removed two loops full of organisms from the tube and deposited them on the marked part of the slide. Describe what you observed in your yeast wet mount, direct stained slide, and indirectly stained slide.
A nucleus was visible in each cell. We opened the petri dishes and dragged the swab over the surface of the agar using our procedure one technique. We closed the lid and used perafilm to seal the edges. How to Write a Micro baterial morphology lab of an Article? These tiny organisms are microscopic when looking at them individually.
With these results, we have a deeper understanding of how prevalent bacteria are, how they grow, their morphology, and how to determine if they are gram-positive or gram-negative. Biochemistry Virtual Lab I Biochemistry is the study of the chemical processes in living organisms.
We emptied and refilled the beakers of tap water. List three reasons why you might choose to stain a particular slide rather than view it as a wet mount.
We used thongs to hold the slide and passed it through the bunsen burner to dry and warm it. This slide was a mixture of different shapes.Be specific. since this is lab report for the identification of an unknown bacterium and the methods are explained in detail in the lab manual. See some of the examples of papers identifying an unknown from the web sited below.
the morphology was observed and recorded and a Gram stain was performed.5/5(1). Microbiology Final Laboratory Report - Free download as Word Doc .doc), PDF File .pdf), Text File .txt) or read online for free. Micro Lab Report. I aseptically conducted another gram stain test using lab exercise seven to be sure of the morphology of my organisms.
On the CNA agar I checked for hemolysis and on the MAC agar I /5(6). Micro Baterial Morphology Lab Bacterial Morphology Part 1: Viewing Prepared Slides of Common Bacterial Shapes Familiarize yourself with each morphological type to use as a comparative tool for the remainder of the activity.
Micro Baterial Morphology Lab Bacterial Morphology Part 1: Viewing Prepared Slides of Common Bacterial Shapes Familiarize yourself with each morphological type to use as a comparative tool for the remainder of the activity. Start studying Micro Lab Preparation of Bacterial Smears/Simple Staining/Negative Staining/Gram Stain.
Learn vocabulary, terms, and more with flashcards, games, and other study tools. We performed a two-part experiment to gain a better understanding of bacteria through gram-staining.
Gram staining is a differential staining method which results in the classification of two groups of bacteria, Gram-positive and Gram-negative.Download
