Abstract excerpt
A gene has been cloned from a DNA library from alkaliphilic Bacillus firmus OF4 that functionally complements a mutant strain of Escherichia coli, NM81, that carries a deletion for one of that strain's Na+/H+ antiporter genes (delta nhaA). The cloned alkaliphile gene restored to NM81 the ability to grow at pH 7.5 in the presence of 0.6 M NaCl and on 100 mM Li+ in the presence of melibiose, and concomitantly led...
