Ph organism
WebThe pH of maximum growth rate is called the optimal growth pH. Based on optimal growth pH, microbes can be separated into three groups: acidophiles grow best at pH < 5, neutrophiles grow optimally at pH between 5 and 9, and alkaliphiles grow fastest above pH 9 ( Horikoshi, 1999; Baker-Austin and Dopson, 2007 ). 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 ...
