So Gram negative bacteria doesnt retains the crystal violet. Current Research in Biotechnology. As a result the cell is stained with the counter stain safranin this taking up its color (pink-red). These microorganisms can have remarkable abilities such that we cannot fathom. P. vulgaris present in water or soil conditions usually indicates fecal pollution, which poses a dangerous health risk when consumed in the form of food or water, such as the occurrence of P. vulgaris in raw shellfish (21). 31(2):318-22. Wound healing is a complicated physiological process that is essential for restoring the epithelial barrier after an injury. When P. vulgaris is tested using the API 20E identification system[1] it produces positive results for sulfur reduction, urease production, tryptophan deaminase production, indole production, sometimes positive gelatinase activity, and saccharose fermentation, and negative results for the remainder of the tests on the testing strip. No the counter stains used is either methylene blue or malachite green. Under a microscope, if the gram stain is purple, the bacterium is gram positive, if the stain is red, it is gram negative. So this method is also called Ziehl-Neelsen staining techniques. After another 48 hours, there were two different unknown bacterium growing on the two different nutrient agar plates used.
