Gram-negative bacteria
Gram-negative bacteria have an outer membrane. However, they have a thinner peptidoglycan cell wall. This means they do not hold the blue dye used in Gram testing and do not appear blue. Instead, they appear red or pink in color.
RED GRAM means KANDI PAPPU
The scientific name for red gram is Cajanus cajan.
The color of a gram-negative stain is pink or red. This staining technique is used to differentiate bacteria based on their cell wall composition, with gram-negative bacteria retaining the pink/red color after staining.
Gram- negative bacteria turns red to pink after the gram stain is performed.
Gram-positive cells are purple and the Gram-negative cells are red.
If you are talking about a Gram Stain, then red. E. coli is Gram negative which means that Safranin will stain it red during a gram stain.
One way to remember that gram negative bacteria turn red is to think of the phrase "red is negative." This reminds you that when performing a Gram staining test, gram negative bacteria will take on the red color.
It's "red gram," i.e. red bean or red lentil (not sure about the English translation -- gram seems to refer to a lot of foods in India).
