Attenuation Of Bacillus Cereus Spores By Different Factors

Abstract

The spore suspension of Bacillus cereus K] ]s was exposed to different concentrations of NaCl. NaNo3 and NaNC>2 as curing agents. The spores were able to tolerate 10% NaCl. Up to 4%, NaNC>3 had little or minor effects on germination and growth of B. Cereus spores. NaNC>2 reduced the viable count of B. Cereus by 1.87 log cycle when administered at 0.1% concentration. Up to 1% it slightly affected the basic response of germination and growth of the bacterium. The spores could grow at pH ranging from 4.0 to 9.8. 10% garlic extract (v/v) reduced germination and growth of B. cereus spores by 1.16 log cycle.
