Summary

Survival rates of Bifidobacterium infantis were compared after concentration by centrifugation, microfiltration and ultrafiltration. The survival of B. infantis was better after concentration by ultrafiltration (144%) than by centrifugation (49%) or microfiltration (84%). The concentrated cultures were frozen or freeze-dried. Survival rates of frozen or freeze-dried cultures were determined for storage periods of 12 weeks. The mean values of viability were of 27, 28 and 45% for frozen concentrates of B. infantis obtained by centrifugation, microfiltration and ultrafiltration, respectively.
