alkaliphile

An extremophile that grows optimally at high pH (9 to 11, alkaline/basic) conditions, which is accomplished by maintaining a lower intracellular pH of ±8, constantly pumping H+ across the cell membrane into their cytoplasm.

Mohsin and colleagues have been studied in 2011 on protease-producing bacteria isolated from different soil, this study isolated alkaliphile Bacillus that its enzymatic activity was in pH: 11.
Nevertheless there are bacterial strains which can thrive outside this limit which belongs to the group of acidophiles (grows in lower pH) or alkaliphiles (grows in higher pH).
Their topics include functional genomics in thermophilic micro-organisms, whether Lake Vostok and the subglacial lakes of Antarctica host life, molecular adaptation to high salt, mechanisms to tolerate metal and acid toxicity, and environmental and taxonomic biodiversity of gram-positive alkaliphiles.
