Cells of Streptococcus mutansUA159 physiologically adapted to acidification during growth at pH 5 in glucose‐limited chemostat cultures were enriched in mono‐unsaturated and longer chain fatty acids compared with unadapted cells grown under the same conditions but at pH 7. Ratios of unsaturated to saturated fatty acids in the cells were, respectively, 1.2 and 0.3. Cyclopropane fatty acids were not detected. Streptococcus sobrinus6715, which is known to have minimal acid‐adaptive capacity, showed only minimal change in membrane fatty acids. |
