alkaliphile


Also found in: Encyclopedia, Wikipedia.

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.

The viable count of alkaliphiles in normal soils is lower than that found in alkaline soils (18,19).
Tiago and Pedersen revealed that all the cultivated strains isolated from alkaline ground water samples were alkalitolerants rather than alkaliphiles (35,36).
0, which confirms that the studied bacterial isolates were alkalitolerants rather than alkaliphiles.
Wagale and co-workers reported that majority of the isolates were Gram-positive, motile rods with few cocci and actinomycetes that were strict alkaliphiles and grew at pH 11.
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.
A Mann-Whitney U test was applied to determine whether the groups were significantly different in terms of Ericales, Betula, Salix, and Saxifraga oppositifolia, the last two considered mild alkaliphiles.
Among bacteria, the Halophiles in comparison to the extensive uses of extremozymes from thermophiles and alkaliphiles, very few Halophilic enzymes have thus far found applications in industries and biotechnology [5, 7].
