Simple or gram? Simple uses methylene blue, gram uses crystal violet
The result of simple staining of microorganisms is that they can be identified and studied under a microscope.
A simple stain reagent is a type of stain, such as crystal violet or methylene blue, that is used to colorize cells or tissues for microscopic examination. These stains bind to cells and provide contrast to make them visible under a microscope. Simple stains are a quick and easy method to visualize the basic morphology and structure of cells.
A simple stain has a positive charge.
The Gram stain for anthrax shows large, Gram-positive bacilli that appear as long chains of cells. Anthrax bacteria stain blue or purple because of their thick peptidoglycan cell wall, which retains the crystal violet dye used in the Gram staining procedure.

Methylene blue stains everything blue.

Bacillus cells stained with malachite green and safranin will appear red under the microscope due to the counterstaining with safranin. Malachite green primarily stains the spores of Bacillus while safranin stains the rest of the cell, resulting in red-stained vegetative cells and green-stained spores.
B. subtilis is indeed a Gram positive rod.However, there is confusion as to whether it is an obligate aerobe or a facultative anaerobe. Although classed as an obligate aerobe, it has been shown to grow under strict anaerobic conditions.

Fleas carry the bacterium Yersinia pestis, formerly known as Pasteurella pestis. The plague bacillus can be stained with Giemsa stain and typically looks like a safety pin under the microscope.
As the cells are transparent, the components cannot be seen clearly through a microscope. We stain the cell so that we can see the components of the cell clearly through a microscope.
A simple stain has a positive charge.
Bacillus subtilis is a Gram-positive bacterium and does not typically show acid-fast staining results. This means that it does not retain the stain when subjected to the acid-fast staining procedure commonly used to detect mycobacteria.
When stained with iodine and observed under a compound microscope the nucleus will stain the darkest. The cheek cell is frequently employed here as they are simple to collect and tend to take the stain easily.
It's simple, because it's a stain.
There are two types of stains, the simple stain and the differential stain. A simple stain colors all objects the same while a differential stain is used to spot differences in microorganisms. A gram stain is a differential stain, which is used to tell the difference in gram negative and gram positive bacteria. A simple stain would stain all the organisms the same and this difference would not be noted. You would be able to determine their shape, whether it is a cocci or bacillus (rod), but not the type. I'm not sure why the simple stain would be preferable unless you just wanted a quick answer as to the shape of the bacteria. In some cases, a wet prep can be made of a presumptive gram positive cocci to tell the difference between bacteria or yeast. Otherwise, I would say that the gram stain is the only way to go.
