Detailed explanation-1: -ALKALIPHILES. These are extremophilic microorganisms which thrives in roughly alkaline environments (8-11), and have an optimum of pH around 10.
Detailed explanation-2: -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).
Detailed explanation-3: -The term “alkaliphile” is used for microorganisms that grow optimally or very well at pH values above 9 but cannot grow or grow only slowly at the near-neutral pH value of 6.5. Alkaliphiles include prokaryotes, eukaryotes, and archaea.
Detailed explanation-4: -Terms Used to Describe Extremophiles For example, acidophiles are organisms that love (phile) acid (acido). Acidophile: An organism that grows best at acidic (low) pH values. Alkaliphile: An organism that grows best at high pH values.
