Abstract:

A description is given of the technique of breaking down yeast cells and the formation of plasma spheres. The plasma spheres for the most part perish within a few days in the culture medium. Part of the plasma spheres goes through a progressive development and plasma forms having different morphological structures are formed. These plasma forms can be kept alive for a long time by transferring them to a new culture medium. They have several nuclei. Many of these plasma forms undergo a further structural change, which concludes with formation of new yeast cells. These secondary yeast cells are polymorphous. The amorphous particles from the homogenized material are incapable of any further progressive development. The yeast cell fragments, i.e., the plasma spheres, are able to regenerate into a normal cell under particular conditions. This regeneration is different from any hitherto known regeneration phenomenon and it passes through specific stages by way of multi-nuclear plasma forms. Author
