Chemical Composition of Cell-Wall Preparations from Strains of Various Form-Genera of Aerobic Actinomycetes

Institute of Microbiology, Rutgers, The State University, New Brunswick, New Jersey

ABSTRACT

Cell-wall preparations were made from more than 140 strains of aerobic actinomycetes representing most of the form-genera that have been proposed. All cell-wall preparations contained as major constituents glucosamine, muramic acid, alanine, and glutamic acid. In addition, cell-wall preparations from various types of streptomycetes and strains of Microëllobosporia contained glycine and LL-,-diaminopimelic acid; those from strains of most Actinoplanaceae and micromonosporae contained glycine and meso---diaminopimelic acid; those from strains of Thermoactinomyces, Microbispora, Dermatophilus, and nocardiae of the madurae-pelletieri group contained meso-,-diaminopimelic acid; and those from strains of Thermomonospora, Micropolyspora, and most nocardiae contained meso-,-diaminopimelic acid, arabinose, and galactose. All the strains used were also studied morphologically.
