Starvation and Recovery of Vibrio

The starvation-stress response of Vibrio (Listoneila) anguillarum

“…The starvation-survival strategies employed by bacteria include at least the adaptive processes of olhgotrophy, spore and cyst formation, and copiotrophy (Ostling et al, 1993;Poindexter, 1981;Rozak & Colwell, 1987;Schut et al, 1993). Copiotrophic bacteria exhibit relatively rapid growth rates under conditions of abundant nutrients and survive starvation without the development of spores or cysts (Nystrom et al, 1990 Starvation-stress in V. anguillarum Matin, 1991;Nystrom et al, 1990;Ostling et al, 1993).…”

In other words, these bacteria survive starvation by expressing genes which enable the cells to enter a starvation-induced adaptation state, which is resistant not only to long-term starvation but also to a variety of physical and chemical stresses, and permits the cells to initiate outgrowth when nutrients are available (Marouga & Kjelleberg, 1996).…”

“…Recent investigations have demonstrated that many non-differentiating bacteria also have the ability to withstand long periods of nutrient limitation and starvation (Matin et al, 1989 ;Morita, 1993;Ostling et al, 1993;Spector & Foster, 1993). Indeed, it has been suggested that in natural environments most micro-organisms face intermittent or prolonged periods of nutrient-limiting conditions and rarely, if ever, grow at rates approaching maximum mechanisms that allow the cells to survive exposure to multiple physical stresses (Givskov et af., 1994b; Jenkins et af., 1988;Ostling et al, 1993). It is thought that the acquisition of such cross-protection during starvation is the result of the expression of starvation-stress proteins (Givskov et af., 1994a;Hengge-Aronis, 1993).…”

“…On: Fri, 11 May 2018 23:03:00 D. R. NELSON a n d OTHERS are able to persist as free-living organisms in-nutrientlimited waters for extended periods of time (Ostling et al, 1993). Their coexistence with the dominant pool of oligotrophic bacteria in carbon-limited waters and their appearance in association with higher organisms suggest a successful life cycle of feast and famine.…”

An essential role for the Escherichia coli DnaK protein in starvation-induced thermotolerance, H2O2 resistance, and reductive division

“…Stationary-phase cells produced by nutrient deprivation (25) or nutrient excess (12) exhibit a distinctive rounded cell shape of reduced volume (33,37,45,46) and a generalized resistance to extremes of heat, oxidizing agents such as hydrogen peroxide (H 2 O 2 ), and sodium chloride (for reviews, see references 28 and 38). Starvation-induced resistance is dependent upon protein synthesis (25) and the regulons controlled by the alternative sigma factors 32 (24) and S (39), encoded by the rpoH and rpoS (katF) genes, respectively (for a review, see reference 36).…”
