WebJan 3, 2024 · Key Points Neutrophiles are organisms that thrive in neutral (pH 7) environments. Alkaliphiles are microbes that thrive in alkaline (pH 9-11) environments. Acidophilic organisms are those that thrive under highly acidic conditions (usually at pH 2.0 or below). Key Terms neutrophile: any organism that thrives in a relatively neutral pH Webneutrophiles- pH 5.5 - pH 8.5 alkalophiles- pH 8.5 - 11.5 pump in protons generate ammonia (+) by ammino acid degradation 3. pressure(remember, low water activity = high osmotic pressure) halophiles- require sodium >9%; extremes may live in 30% marine salt about 3% cell wall and membrane fall apart w/o sodium nonhalophile - 0 to 1.5%
WebJan 30, 2024 · For example, a pH of 3 is ten times more acidic than a pH of 4. Likewise, a pH of 3 is one hundred times more acidic than a pH of 5. Similarly a pH of 11 is ten times more basic than a pH of 10. Properties of the pH Scale From the simple definition of pH in Equation 4, the following properties can be identified:
WebFeb 10, 2024 · Microorganisms that grow optimally at pH less than 5.55 are called acidophiles.
