title: [Population of L-forms of Bacillus subtilis studied in Ficoll density gradients].
abstract: The distribution of cells in the population of L-forms of Bas. subtilis was analysed by isopicnic centrifugation in density gradient of ficoll. Two main fractions of L-forms different in their density were found. The study of the fractions by various methods indicated that a considerable part of the L-forms population is presented by unviable cells of diverse size with fragments of genome or without DNA.
