Methods — what steps did you take to complete the experiment? Bacteriology Gram staining is a very important technique used in biology labs all over the world.
I hypothesize that in the cultures used in this lab for gram staining will contain many gram negative and gram positive bacteria.
One of the odd things noticed about the gram sensitive bacteria is that the gram negative bacteria were gigantic compared to the gram positive bacteria 3XX larger. After conducting the bacteria gram staining experiment we sawbbed three things and let each incubate for a week.
After doing a gram stain do you have a. Draw the cells showing morphology, grouping, and relative sizes. Prepare and heat-fix smears. Of course, you can use the structure we have provided above and write a lab report yourself. If you choose the latter option, we can guarantee that: Many different types of both gram negative and gram positive bacteria were identified.
Bacteria, and can be inconsistent in older populations maintained in the laboratory. Page 1 of 2. The title explains what kind of experiment you performed and what was its main point. Results and Discussion — a very important part to write lab report that actually matters.
It should be sufficiently detailed for anyone to be able to repeat your experiment. Flood the crystal violet for one minute. Or, you can leave the daunting part to us. Pour off excess dye and wash gently in tap water and drain the slide against a paper towel. AugustChapter 7: Color a few of the cells of each bacterial species to show the Gram reaction.
Both staining methods are useful when you want to get some basic information about tested cultures size, shape, arrangement. Figures and Graphs — additional materials that must be clearly labelled. References — what materials you used when you cited the facts in your experiment This is a generic structure of a lab report, so you should use a specific one if any given to you by your instructor.

It is almost always the first test performed for the identification of bacteria. Introduction — a part that explains the purpose and the objectives of the laboratory experiment. One of the gram positive types of bacteria in the cultures that were interesting to me were some that came in colonies of four.
Lab report writing comes after you have done the required experiment.LAB REPORT OF MICROBIOLOGY. Download. LAB REPORT OF MICROBIOLOGY.
Uploaded by. Akbar Haqi. Introduction Microorganism is an organism that is microscopic or submicroscopic, which is too small to be seen under naked eyes. However, the numbers of microorganisms in a given sample are required to know in certain aspect such as dairy industries.
Bacteria that are non-responsive to this technique are known as gram insensitive. I hypothesize that in the cultures used in this lab for gram staining will contain many gram negative and gram positive bacteria. MICROBIOLOGY UNKNOWN LAB REPORT. Unknown Number Jennifer Mills.
April 30, Microbiology, BIO Spring/ INTRODUCTION In the past, it has been vital to distinguish the identities of microorganisms in the world.
UNKNOWN LAB REPORT.
Unknown number Clare Zilch. December 3, The two microorganisms were identified; one was a Gram-positive bacteria, the other was a Gram-negative bacteria.
A series of biochemical tests were performed based on the results of the Gram stains. Since 19th century scientists were aware of some unique identity of an individual which distinguish from others, like finger prints.
InDNA was established as key element in human life and which makes individual as unique creature. Unknown Bacteria Lab Report Essay Introduction The purpose to this lab was to isolate and identify two unknown bacteria from a mixed culture provided to us by our instructor.
This study was done by applying all of the methods that have been instructed on thus far in microbiology laboratory class.Download
