THE VITALITY OF CELL FRAGMENTS OF YEAST. III. REGENERATION OF CELLS FROM PLASMATIC FORMATIONS,
Abstract
In the surface layers of a yeast culture during autolysis under known conditions there takes place a breaking up of the cell membranes. The liberated plasma is not subjected to proteolysis but forms plasmatic droplets. These plasmatic globules develop completely the same as plasmatic droplets obtained by a mechanical disintegration of cells. It is possible to conduct a reinoculation of plasmatic formations in cultures separate from yeast cells, since in a number of passages they grow continuously for several months. The form of these growing formations for the most part is completely irregular, seldom maintaining a specific type of growth. The method of regeneration described is different from the regeneration of cell fragments described in literature for other vegetative substances. The regeneration of cell fragments of yeast proceeds in several stages: (1) the plasmatic droplet, (2) multinucleate plasmatic formation, (3) dense plasmatic formation, (4) genesis of cells by budding.
