Microbiology Chapter 4-6 Terminology
Chapter 4 Terminology
1. aerotolerant anaerobes- bacteria that do not require oxygen; its
presence neither hinders nor helps the growth of the organisms.
2. Autotrophs- tissue transplanted from one site in an individual to
another site in the same individual
3. Bacilli- rod-shaped bacteria, some of which are endospore forming
4. Barophiles- microorganisms that grow best under high hydrostatic
pressures and live only in the deepest parts of oceans
5. Barotolerant- microorganisms that can survive under conditions of
increased hydrostatic pressure
6. binomial system- the system of nomenclature in which organisms are
identified by a two-part Latinized name. It was devised by Linnaeus
and therefore is also referred to as the Linnaean system
7. Capneic- describing bacteria (capnophiles) that require more carbon
dioxide than is present in the normal atmosphere
, 8. Carbon- a naturally abundant chemical element with the symbol C
and the atomic number 6. Carbon provides the backbone of all organic
molecules
9. Chemoautotrophs- uses inorganic chemical compounds as the source
of energy and carbon dioxide as the carbon source
10. Chemoheterotrophs- uses organic compounds as both the source
of energy and as a carbon source
11. Chemotrophs- an organism that uses energy from the breakdown
of nutrient molecules
12. Cocci- spherical bacteria; plural of coccus
13. Cryophiles- bacteria that are cold-loving and can grow at 0°C or
lower with optimal growth at about 15°C; also called psychrophiles
14. death phase- the death phase of bacterial growth begins when
growth stops and the number of dead cells is larger than the number of
viable cells
15. Diplococci- round bacteria (cocci) that remain paired after cell
division
