[Relationship between the number of nucleoidosomes and the stage of development of Mycobacterium rubrum cultures].

This work has confirmed that the nucleoidosome (mesosome) of Gram-positive bacteria is a specialized invagination of the cytoplasmic membrane and serves for accommodating the replicative centres of nucleoid homologous chromosomes. The structure is not constant, it arises under specified conditions of cultivation and at certain growth stages which are characterized by decelerated division of nucleoids and cells while the rate of DNA replication does not change.
