Streptomycetes in the Light of the Concept of Multicellularity of Bacteria

Abstract

The review concerns discussion of certain aspects of growth and development of streptomycetes, that have an adaptation meaning for their existence under natural conditions and reflect our perception of them as procaryotes which have a range of qualities typical of multicellular organisms. At present, the concept of multicellularity is the key idea in investigation of growth processes, differentiation and physiology of streptomycetes. Streptomyces olivocinereus is presented as an effective model that gives the unique opportunities for investigation of different aspects of biology of streptomycetes within laboratory environment as well as in natural environment in suti. S.olivocinereus produces luminescent antibiotic geliomycin (resistomycin). In this review we summarized the results of the many years of investigation of growth, differentiation and behavior of this streptomycete. The investigations were undertaken by a group of scientists of the Moscow State University. The results can be employed as arguments for the multicellular nature of streptomycetes.
