Gram Discolor
Bacteria Identification
Following common procedure for Gram staining, a slide was prepared by heat fixing the sample and applying the principal crystal purple stain (Bruckner, 2012). Following incubation inside the primary discolor for a length of one minute, the stain was rinsed within slow stream of drinking water for 4 seconds before fixing the rest of the dye with Gram’s iodine, with concentration in this mordant lasting one minute (Bruckner, 2012). Following this, an additional rinse employing acetone, again poured in a really slow stream and this time lasting for less than three just a few seconds, removed virtually any non-fixed crystal violet and left behind only the dye set within the Gram-positive bacteria in the sample (Carleton, 2012). Safranin was added as a secondary stain and incubation again lasted one minute, with a rinse out of four mere seconds under a slower stream of water taking place before examination of the glide (Carleton, 2012). All visible bacteria were dyed violet, meaning the sample was of a Gram-positive species (Bruckner, 2012). The bacteria were arranged within a hash-mark pattern noticeable in larger gatherings of cellular material, though meaning of these groups and of specific bacteria has not been especially excessive.
Endospore Discolor
A sample glide was ready and heat fixed, then simply placed on cable gauze in a ring stand and absorbent paper set directly on the sample (Rossbach, 2012). The paper was saturated with malachite green and the slip then heated with a Bunsen burner until steaming (Rossbach, 2012). Dye and heat were added alternately just to the point of steaming for three mins, with heat removed as soon as steaming happened and coloring added only when the conventional paper was dried out, taking care not to over-saturate or overheat the test (Rossbach, 2012). The daily news was then removed as well as the slide rinsed for 20 or so seconds within steady stream of warm water, and a counter discoloration of safranin was applied in an concentration lasting 45 seconds (Rossbach, 2012). Endosporic cells from this staining process retain the green malachite dye, while different organic matter retains only the red safranin counterstain; declaration of the discolored slide unveiled only green structures, in a similar agreement as observed in the Gram stain method, suggesting a Gram-positive endosporic bacteria.
Negative Stain
A tiny drop of nigrosin discolor was put to one part of a washed and flamed slide, and a small loop of the bacterias was placed in the center with the dye pool (Rossbach, 2012). A second cleaned and
