| Popis: | The changes in physiological and biochemical properties of Pseudomonas fluorescens 26K, a degrader of chlorinated aromatic compounds, were revealed after existing in a dormant state as cyst-like cells (CLC). The CLC maintained the ability to form colonies after long-term storage, possessed enhanced resistance to damaging factors (heating and drying), and had specific ultrastructural organization. In populations grown from CLC on solid media, we observed the appearance of phenotypic variants, which differed from the dominant type in the shape, consistency, and pigmentation of colonies. The emerging phenotypes had higher growth rates on some aromatic substrates, which required the enzymes with broadened substrate specificity for their utilization. |
