Microbiology Microbiology is the study of Microorganisms that we can not see by naked eye.
Bacteria
Most bacteria are 0.2μm (micron) in diameter and 2−8μm (micron) in length . Bacterial cells are about one-tenth the size of eukaryotic cells.
Gram-negative bacteria are surrounded by a thin peptidoglycan cell wall, which itself is surrounded by an outer membrane containing lipopolysaccharide . Gram-positive bacteria lack an outer membrane but are surrounded by layers of peptidoglycan many times thicker than is found in the Gram-negatives. Threading through these layers of peptidoglycan are long anionic polymers, called teichoic acids .
Sterols are a group of fat-like substances that occur naturally in plants and animals. They are important components of biological membranes and play essential roles in cell structure, function, and physiology.
