Abstract
Properties of acid tolerance of an adipic acid-resistant mutant, Leuconostoc paramesenteroides (ANaP100) were studied and compared with those of its paired wild type of Leu. paramesenteroides (LPw). The value of protons permeability of LPw after an acid shock at pH 5.0 was 4.3 min, while the value of ANaP100 was 4.8 min at the same pH. The maximal specific activities of ATPase of LPw and ANaP100 were 0.59 unit/mg protein and 0.63 unit/mg protein at pH 6.0, respectively. The release of magnesium ion from the mutant strain was about 27.3% at pH 4 after 2 hrs, while the wild strain was about 52.2% under the same conditions. The contents of
