The cells of alkalophilic Bacillus sp. C-125 are shaped by peptidoglycan and enclosed by two acidic polymers (teichuronic acid and teichuronopeptide), which bind to the peptidoglycan. Three kinds of mutant strains defective in these acidic polymers were isolated from the strain C-125. These mutants grow poorly at alkaline pH to extents related to the degree of defect in the polymers, suggesting that these acidic polymers are essential for growth in an alkaline environment. These polymers may diminish penetration of hydroxide ions.
