title: [Composition of Actinomyces hygroscopicus membranes].
abstract: The composition of membranes was studied in four strains of Actinomyces hygroscopicus differing in their morphologo-cultural characteristics and synthesis of antibiotic hygromycin and enzyme hygrolytin. The composition of the membranes was not the same and varied in the course of growth and development. The content of proteins and carbohydrates increased in the membranes, particularly in the strains producing enzymes. In the process of growth, the content of phospholipids increased in the lipid component of the membranes, and the ratio between the main phospholipids, i. e. phosphatidyl ethanolamine and cardiolipine, changed. The spectrum of fatty acids of phospholipids did not change in the course of growth.
