Abstract

856 857 859 859 In the natural environment bacteria seldom encounter conditions that permit periods of exponential growth. Rather, bacterial growth is characterized by long periods of nutritional deprivation punctuated by short periods that allow 855 0066-4227/93/1001-0855$02.00 KOLTER, SIEGELE & TORMO fast growth, a feature that is commonly referred to as the feast-or-famine lifestyle. In this chapter we review the recent advances made in our understanding of the molecular events that allow some gram-negative bacteria to survive prolonged periods of starvation. After an introductory description of the properties of starved gram-negative bacteria, the review presents three aspects of stationary phase: entry into stationary phase, responses during prolonged starvation, and reentry into the growth cycle. INTRODUCTION In the natural environment bacteria seldom encounter conditions that permit continuous balanced growth. When nutrients are plentiful, bacteria can sustain relatively fast growth rates. But the very fact that bacterial populations can use nutrients efficiently to generate rapid increases in their biomass means that they are nutritionally starved most of the time. Still, these organisms can survive for extremely long periods in the absence of nutrients. Laboratory conditions do not exactly reflect what bacteria find in nature.
