The amino acid incorporation and alpha-amino-isobutyric acid (AIB) uptake of an alkalophilic Bacillus grown at pH 8.2 (the pH 8-bacteria) were much less pH dependent (less alkalophilic) than those of the organisms grown at pH 10.0 (the pH 10-bacteria), respectively. The rate of AIB uptake of the pH 10-bacteria was almost the same as that of the pH 8-bacteria, while the rate of amino acid incorporation of the pH 10-bacteria was higher than that of the pH 8-bacteria in alkaline environments. The colloidal titration with clupein showed that the amount of negative charge on the pH 10-bacteria was greater than that of the pH 8-bacteria in alkaline environments. Considerable difference in protein composition was observed between the membranes of the pH 8- and 10-bacteria while no difference was observed in phospholipid composition.
