title: Decrease in cytoplasmic pH-homeostastatic activity of the alkaliphile Bacillus lentus C-125 by a cell wall defect.
abstract: Cytoplasmic pH homeostatic activities of cell wall-defective derivatives of the alkaliphile Bacillus lentus C-125 were assessed using a pH-sensitive fluorescent probe, BCECF. It was shown that the acidic cell wall components took part in maintenance of the cytoplasmic pH neutrality at alkaline pH.
