Alkaliphilic
Alkaliphiles are a class of extremophilic microbes capable of survival in alkaline ( pH roughly 8.5–11) environments, growing optimally around a pH of 10. These bacteria can be further categorized as obligate alkaliphiles (those that require high pH to survive), facultative alkaliphiles (those able to survive in high pH, but also grow under normal conditions) and haloalkaliphiles (those that require high salt content to survive).HORIKOSHI, KOKI. "Alkaliphiles: Some Applications of Their Products for Biotechnology." MICROBIOLOGY AND MOLECULAR BIOLOGY REVIEWS 63.4 (1999): 735-50. Print. Background information Microbial growth in alkaline conditions presents several complications to normal biochemical activity and reproduction, as high pH is detrimental to normal cellular processes. For example, alkalinity can lead to denaturation of DNA, instability of the plasma membrane and inactivation of cytosolic enzymes, as well as other unfavorable physiological changes.Higashibata, Akira ...
