Bacterial Identification Lab Worksheets are the next best thing to a digital laboratory. You will be able to save your results for reference in the future. In addition, you can simply print out your results for your own records. You can also use it as a teaching tool when you are conducting your own experiments or teaching students on how to identify and isolate bacteria in their experiments.
One of the easiest ways to use this worksheet is by grouping similar species together. For example, you may want to group a number of bacteria together to compare their species. You may also want to place them in a similar group such as anaerobic. For instance, an anaerobic group may be similar to an aerobic group. If you do not know the species of anaerobic bacteria, simply identify them on the forms that come with the LabWorksheet.
One of the most important things that you need to remember when it comes to identifying bacteria in your lab is what they look like. The bacteria may be white, black, yellow, pink, red, brown, or any other color. The reason you need to know this is because it helps you determine whether or not the bacteria you are looking at is in the form you are looking for. The best way to tell the difference between bacteria is to use a light source to help them glow. This is the best way to identify which one you are looking at.
The best way to begin your study of the organisms you may have seen in your lab is to isolate them by collecting a small sample. A culture can also be used to isolate the sample for your analysis. After you collect the sample, simply place it in a jar and label it as a culture and place it in a separate place where it is away from your workstation. You may want to add a title on it such as “Fluke’s Measured”.
Next, you will need to culture the cultures of the bacteria that you collected. To do this, insert a culture tube into the pipette with the tip being inserted through the top of the glass in the jar. Push the tip through the glass to allow it to fit into the tube. Insert the tube and gently push the pipette through the glass so that the needle will go all the way through the top of the glass.
Place the second end of the tube into a Petri dish along with the cap on and label it as a culture plate. Place it in a separate location where it will not be disturbed until you can collect it for analysis.
Once you have begun to examine the different organisms on the culture plate, draw a line from one center to the next until you are satisfied that you have identified them. If you find yourself with more than one organism on the plate, don’t worry, just label them according to their genus. You can still use these plates as references for identifying the particular species of organism you are examining.
Finally, analyze the cells on the culture plate using any method such as fluorescent in situ hybridization, immunofluorescence staining, or cell divisions. Identify all of the cells that have DNA from the organism that you are studying and submit these to your laboratory and obtain the results that you need.
