Also, microflora is usually restricted to lactic acid bacteria when PH was low
(Luna-Guzman and Barrett, 2000). Calcium chloride enhance tissue resistance to bacterial
attach by stabilizing or strengthening cell walls (Mayer and Harel, 1991). For calcium
compound, it was reported that the antimicrobial property was due to calcium ability to
uncouple microbial transport processes (Saftner et al.,2003).
