[Spatial distribution of synthetic activity in zone-forming colonies of soil Streptomycetes].

The space distribution of synthetic activity in the substrate mycelium gyphs--structure growth units of a quasiorganism of the radiant fungus, was studied by the method of microspectral analysis. A detailed map of the distribution on the alpha-parameter (which reflects the level of synthetic activity) from the cross section of a living streptomyces colony was constructed. The data obtained support with a high reliability the earlier supposition that the maximum of synthetic activity is in the growth zone and the minimum synthetic activity is in the globular regions of formation of air mycelium protogyphs. The use of objectivity characteristics made it possible to thoroughly study the development of globular structures, the precursors and sources of formation of air mycelium concentric zones on colony surface.
