title: [Features of secretion of bacteriolytic enzymes and polysaccharides in bacteria from the Pseudomonadaceae family].
abstract: It is shown that secretion of bacteriolytic complex enzymes in a bacterium of the family Pseudomonadaceae begins in the latent and early logarithmic culture growth phases. A maximum of specific bacteriolytic activity falls in the same time interval with a maximum of specific activity of lytic proteinase L2 and muramidase. The activity of concomitant enzymes--non-specific proteinase and neutral phosphatase--peaks in the middle of the logarithmic growth phase. Secretion of exopolysaccharide into the external medium begins in the second half of the logarithmic growth phase and, thus, is not coordinated with secretion of bacteriolytic enzymes. It is shown that relative content of enzymes and polysaccharides depends upon the composition of growth medium for the producer.
