General Physiology of Alkaliphiles
Generally, alkaliphiles require alkaline environments and sodium ions not only for growth but also for sporulation and germination. Sodium ion-dependent uptake of nutrients has been reported in some alkaliphiles. Many alkaliphiles require various nutrients, such as polypeptone and yeast extracts, for their growth; several alkaliphilic Bacillus strains (Bacillus halodurans C-125, A-59, C-3, and AH-101) can grow in simple minimal media containing glycerol, glutamic acid, citric acid, etc. One of the best strains for genetic analysis is alkaliphilic B. halodurans C-125 and its many mutants have been made by conventional mutation methods. Whole genome sequence was determined and annotated in 2000 (Takami et al. 2000).
Extracellular pH Values
Alkaliphilic microorganisms are ubiquitous: Many alkaliphilic bacteria and archaea can be isolated more commonly from the earth. Alkalinity in nature may be the result of the geology and climate of the area, of industrial processes, or promoted by...
