Gram positive vs gram negative bacteria differences

The difference between gram positive vs gram negative bacteria is based on their staining color during the gram stain test. Using the gram staining technique, bacteria have been differentiated into gram-positive and gram-negative bacteria. The ability to differentiate bacterial cells is essential for various reasons. This host of reasons varies from diagnosing infection to checking … Read more

Gram positive bacteria: examples and structure

The most common gram-positive bacteria examples include Staphylococcus, Streptococcus, Bacillus, Clostridia, Listeria, and Corynebacterium. These gram-positive bacteria representative species are pathogenic and cause several diseases. All gram-positive bacterial cells are bounded by a single-unit lipid membrane. Generally, the cell walls of gram positive bacteria contain a 20-80 nm thick layer of peptidoglycan. This peptidoglycan is … Read more

Do bacteria have cell walls?

Nevertheless, the cell wall of bacteria is not like that of plants and other organisms due to the presence of peptidoglycan (also known as murein) which is located immediately outside the cell membrane. The bacteria cell wall is made up of peptidoglycan which makes the cell wall rigid and determines the cell shape. The structure … Read more
