Summary

SIGNIFICANTLY HIGHER POPULATIONS WERE OBTAINED BY 2 CULTURES DURING GROWTH AT EITHER PH 5 OR 5.5 THAN AT HIGHER PH. FREEZING AND FROZEN STORAGE FOR 28 DAYS AT 77 K (-196 DEG C) HAD NO SIGNIFICANT EFFECT ON THE VIABILITY. HOWEVER, THERE WERE SIGNIFICANT EFFECTS ON THE VIABILITY OF THE CULTURES DURING SUBSEQUENT STORAGE AT 278 K (5 DEG C) IN MILK. CELLS OF BOTH STRAINS GROWN AT PH 5 DID NOT EXHIBIT ANY SIGNIFICANT DECREASE IN VIABILITY DURING 21 DAYS AT 278 K. CELLS OF BOTH STRAINS GROWN AT ALL HIGHER PH EXHIBITED SIGNIFICANT DECLINES IN VIABILITY DURING THIS SAME STORAGE PERIOD AT 278 K.
