I guess so, and that's why you put out the flame after that.
Passing a slide sample through a flame is known as heat-fixing. This process helps to adhere the specimen to the slide and kills any living organisms present, readying it for staining.
To heat fix a bacterial smear you would put the specimen on the slide and either put slide on a slide warmer or over a Bunsen burner for a few seconds. Heat fixing a bacterial smear does kill the specimen but it makes the bacteria stick the slide to withstand the rinsing process.
If no heat fixing was done to a slide with a specimen on it, it would be rinsed off with the gram staining procedure. Heat fixing the specimen does kill specimen but it also locks it in place.
Fixing the bacterial film helps preserve the structure of the microbial community and facilitates further analysis such as microscopy and molecular studies. It allows for a more accurate representation of the bacteria present and their interactions.
You heat fix a slide by passing it through a blue flame a couple of times (with th cells facing up). you do this to denature any enzymes that might lyse the cells or interfere with the staining procedure. you also use it kill the organism and to adhere the organism to the slide for staining
a heat fix is something you put on the slide
Applying too much heat while heat fixing a slide can cause the sample to dry out too quickly, leading to distortion or loss of cellular structures. Additionally, excessive heat can cause the slide to crack or shatter, ruining the sample. It is important to use gentle heat when fixing slides to ensure optimal preservation of the sample.

Slight heating helps in fixing the cells on to the surface of the glass slide

It helps the cells adhere to the slide so that they can be stained. The purpose of heat fixing is to kill the organisms without serious distortion. They adhere better to the slide and also take up dye more easily.
First and foremost, the purpose of heat fixing is to drive stain into the bacterial cells, which in this case, you are staining the background, so there is not a need for heat fixing. Next, the process of heat fixing will shrink the cell by a little. This sorts of support the first reason as since there isn't the need to heat fix, then don't. By not heat-fixing, we actually see a more accurate morphology, arrangement and size of thr bacterial cell. Hope that my answers helps 😊

If a bacterial smear is not heat fixed prior to staining, the bacteria may not adhere well to the slide and can wash away during the staining process. Heat fixing helps to kill the bacteria, firmly attach them to the slide, and improve the uptake of stain, resulting in better staining results. Without heat fixing, the bacteria may not stain properly or may not be visible at all under the microscope.
