[Characteristics of the metabolism and multiplication of dehydrated Saccharomyces cerevisiae yeasts during their reactivation].
The growth of dehydrated and original cells of Saccharomyces cerevisiae 0-14 was studied in the conditions of reactivation. The identical amount of biomass having the economical growth coefficient of 58-59 percent was accumulated in both variants after 6 hours of growth. The composition and quantitative proportions between free amino acids were studied in the cells of the two cultures. Dehydrated cells lost up to 10 per cent of free amino acids in the course of rehydration. The dynamics of changes in the composition of the amino acid pool in rehydrated dry cells differed from that in pressed yeast cells. By the end of reactivation however, the qualitative composition and the level of the amino acid pool were similar in the cells of the two variants. The yield of growth of reactivated cells in the course of following cultivation was by 16 per cent higher than that of pressed yeast cells grown under the same conditions.
