Cell (biology) made up of cellulose, fungi cell walls are made up of chitin and bacteria cell walls are made up of peptidoglycan. A gelatinous capsule is present in some bacteria outside the cell membrane and cell wall. The capsule may be polysaccharide as in pneumococci, meningococci or polypeptide as "Bacillus anthracis" or hyaluronic acid as in streptococci. Capsules are not marked by normal staining protocols and can be detected by India ink or methyl blue; which allows for higher contrast between the cells for observation. Flagella are organelles for cellular mobility. The bacterial flagellum stretches from cytoplasm through the cell membrane(s)
Glucose oxidase niger". Glucose oxidase is synthesized in several species of fungi and insects where it is used to produce hydrogen peroxide which in turn kills bacteria. Notatin, extracted from antibacterial cultures of "Penicillium notatum", was originally named Penicillin A, but was renamed to avoid confusion with penicillin. Notatin was shown to be identical to Penicillin B and glucose oxidase, enzymes extracted from other molds besides "P. notatum"; it is now generally known as glucose oxidase. Early experiments showed that notatin exhibits "in vitro" antibacterial activity (in the presence of glucose) due to hydrogen peroxide formation. "In vivo" tests showed that notatin
