Effects of organic acids and low pH on Rhizobium meliloti 104A 14

Sensitivity of Rhizobium meliloti to pH that ranges from 5.5 to 6.0 is further affected by organic acids such as monocaryboxylic and acetic acids. Growth is inhibited when the internal pH value goes below 7.15. The coupled effect of organic acids and low pH is determined to be bacteriostatic.
