[Influence of illumination on thermogenesis of growing cultures of halophilic bacteria].

1. Formation of purpuric membranes depends on the light spectral composition applied for culture illumination. 2. Red light turned to be less favourable for the formation of purpuric membranes, the blue one was more favourable for this purpose. 3. Thermogenesis of the culture giving the greatest yield of purpuric membranes is plotted by the curve with a large number of falls of thermogenesis. 4. At a decrease of cultivation temperature even under the blue light the formation of purpuric membranes is inhibited. 5. The decrease of thermogenesis at definite moments of cultivation of halophiles is concerned with the formation of purpuric membranes in the cells.
