Description
English: Aerobically different bacteria behave differently when grown in liquid culture:
  1. Obligate aerobic bacteria gather at the top of the test tube in order to absorb maximal amount of oxygen.
  2. Obligate anaerobic bacteria gather at the bottom to avoid oxygen.
  3. Facultative bacteria gather mostly at the top, since aerobic respiration is advantageous (ie, energetically favorable); but as lack of oxygen does not hurt them, they can be found all along the test tube.
  4. Microaerophiles gather at the upper part of the test tube but not at the top. They require oxygen, but at a lower concentration.
  5. Aerotolerant bacteria are not affected at all by oxygen, and they are evenly spread along the test tube.
Polski: Bakterie beztlenowe od tlenowych można rozróżnić przez hodowlę na płynnym podłożu w zależności od wymagań tlenowych będą się rozwijać w rożnych optimach stężenia tlenu wzdłuż malejącego gradientu stężenia dyfundującego 02 :
  1. Obligatoryjne tlenowce zbierają się przy powierzchni, gdzie dyfunduje najwięcej tlenu.
  2. Obligatoryjne beztlenowce żyją na dnie, gdzie jest najmniej tlenu.
  3. Fakultatywne tlenowce żyją głównie przy powierzchni, gdyż tlen zwiększa ich metabolizm; ale tlen im nie szkodzi.
  4. Mikroaerofilne pływają w górze, ale nie tuz przy powierzchni. Lubią tlen, ale w małym stężeniu.
  5. Tolerujące tlen bakterie 02 nie afektują i rozmieszczają się wzdłuż całej probówki. (rysunek poprawny przy założeniu, że opadanie jest wolniejsze niż tempo rozwoju, lub że mikroby pływają swobodnie)
