Bacteria Classification by Gram Staining Essay - 820 Words.

Gram satin: Bacteria can be divided into two main groups, gram-positive or gram-negative, based on the structure of their cell wall and their reaction to thegram stain.

Gram staining method, the most important procedure in Microbiology, was developed by Danish physician Hans Christian Gram in 1884. Gram staining is still the cornerstone of bacterial identification and taxonomic division. This differential staining procedure separates most bacteria into two groups on the basis of cell wall composition.
