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 vs Gram Negative | Technology Networks The diagram below illustrates the differences in the structure of Gram positive and Gram negative bacteria.

Difference Between Gram-positive and Gram-negative Bacteria The gram-positive bacteria retain the crystal violet colour and stains purple whereas the gram-negative bacteria lose crystal violet and stain red. Thus, the two types of bacteria are distinguished by gram staining. Gram-negative bacteria are more resistant against antibodies because their cell wall is impenetrable. Gram negative diplococci bacteria: Introduction ... Gram Staining: The diagnosis is suggested by the finding of gram-negative bacteria bean-shaped capsular ( mark of evidence in Gram stain) diplococci as shown above image but the capsular mark is not recovered gram stain from culture. Culture: The organism is cultured on blood agar or chocolate agar incubated at 37°C in a 5% CO 2 atmosphere.
