It is important to note that not all bacteria have a cell wall.Having said that though, it is also important to note that most bacteria (about 90%) have a cell wall and they typically have one of two types: a gram positive cell wall or a gram negative cell wall.. The two different cell wall types can be identified in the lab by a differential stain known as the Gram stain.

Structure of Bacteria (With Diagram) | Microbiology 8. According to Peberdy (1980) the only compound present in the cell walls of both Gram-negative and Gram-positive bacteria is 'peptidoglycan'. The cell walls of Gram-positive bacteria contain up to 95% peptidoglycan and up to 10% teichoic acids. 9. Cytoplasmic membrane is a thin (5-10 nm) layer lining the inner surface of the cell wall. Gram Positive and Gram Negative Bacteria - Structures ... Gram positive bacteria are a group of organisms that fall under the phylum Firmicutes. However, a few species have a Gram negative cell wall structure. As compared to Gram negative bacteria, this group of bacteria is characterized by their ability to retain the primary stain (Crystal violet) during Gram staining (giving a positive result). ...
