MCB 3020 Lecture Notes - Lecture 35: Oxidase Test, Pseudomonas Aeruginosa, Chemical Formula
Document Summary
Multicellular, two anterior suckers, flat leaf shape, blind alimentary tract hermaphodites. Nutrition: ingestion or absorption of body fluids, tissue, or digestive contents. Location for trematodes = bill (blood, intestine, liver, and lungs) Multicellular, head structure which contains a hook that they use to attach onto the intestinal wall. Motility: no single organelle; usually attachment to mucosal possible muscular motility. Nutrition: they absorb their nutrients through their outer coating. Use organic compounds as both their carbon source and energy source. Uses inorganic compounds (such as no3-) as the final electron acceptor. Uses organic compounds as the final electron acceptor. The substance will turn red if mixed acids are produced from fermentation (ph < 4. 4) Used to differentiate between different gram negative bacteria. Cytochrome oxidase (an etc enzyme present in some species such as p. aeruginosa) If it has a particular enzyme, it will immediately turn blue.
