Summary

The effect of growth phase of cells, cryoprotectant agents and freezing rate on the survival of selected microorganisms (Bacillus cereus, Lactobacillus plantarum, Escherichia coli, Pseudomonas fluorescens, Saccharomyces cerevisiae, Kluyveromyces lactis, Candida utilis, Mucor racemosus, Aspergillus niger) during freezing and thawing was studied. In cases where significant differences were observed, stationary phase cells always survived better than exponential phase ones, while horse serum + inositol was always superior to skimmed milk powder + inositol. The effect of freezing rate was different among the microorganisms studied.
