Аннотация:The viability of lyophilized microorganisms belonging to different physiological groups was determined after 50-year storage at 2-4 degrees C. During this period, the number of viable cells gradually decreased, in some cases, by 2-3 orders of magnitude. However, after 50-year storage, the ampoules contained considerable amounts of viable cells (in many cultures, 10(6)-10(9) cells) that were quite sufficient for the culture maintenance. All the studied lyophilized microorganisms (pro- and eukaryotes) retained their viability after 50-year storage, a longer period than those known in literature.
