EVOLUCIJA BAKTERIJA TIJEKOM STACIONARNE FAZE RASTA
Bacteria are exposed to changing environmental conditions. Their survival depends on detection of extracellular signals which are important to initiate cellular response. In adverse conditions non-sporulating bacteria enter in stationary growth phase and try to maintain viability. Bacteria developed complex mechanisms of adjustment during the stationary growth phase to maintain their presence. The modifications are observed in bacterial morphology, physiology and metabolism. Response mechanisms are regulated through global molecular transcriptional regulators. Stationary phase is the source of genetic diversity and instability therefore, mutans with better fitness than parental cells continuously arrive. Growth of parental and emerging mutant populations is defined as competitive, which is described as growth advantage in stationary phase phenomenon.
