title: [Role of PSD2 and GPS A20 genes in lethal processes in Escherichia coli found in the air].
abstract: Comparative experiments on auxotrophic E. coli grown in rich nutrient L-broth have demonstrated that the influence of genes psd 2 and gps A 20 responsible for the synthesis of phospholipids in the bacterial membranes on the viability of the cells is unessential. The cultivation of strain BB 20-14 in a minimal E medium with different glycerophosphate admixtures has shown that the decrease of phospholipid content in the cells to one-third of the original level leads to a considerable change in the viability of the cells in the air.
