Web[1] A neutrophile is a neutrophilic organism [2] that thrives in a neutral pH environment between 6.5 and 7.5. [3] Environment [ edit] The pH of the environment can support growth or hinder neutrophilic organisms. When the pH is within the microbe's range, they grow and within that range there is an optimal growth pH. [4] WebThere are mechanisms in organisms that regulate pH and this regulation is an example of homeostasis. For example, if you have learned about buffers, then it may help to know that essentially all organisms use buffers (and other mechanisms) to maintain control over the pH — for example the different organelles within eukaryotic cells will ...
