They Get at the very best in the tube exactly where the oxygen concentration is maximum. 2: Obligate anaerobes are poisoned by oxygen, so they Acquire at The underside of your tube exactly where the oxygen concentration is lowest. 3: Facultative anaerobes can grow with or with out oxygen because they can metabolise energy aerobically or anaerobically. They Assemble typically at the best simply because aerobic respiration generates much more ATP than possibly fermentation or anaerobic respiration. four: Microaerophiles require oxygen since they can't ferment or respire anaerobically. having said that, They are really poisoned by higher concentrations of oxygen.
