The stationary phase of the bacterial life cycle.
Kolter R, Siegele DA, Tormo A. Kolter R, et al. Among authors: tormo a. Annu Rev Microbiol. 1993;47:855-74. doi: 10.1146/annurev.mi.47.100193.004231. Annu Rev Microbiol. 1993. PMID: 8257118 Review.
Rather, bacterial growth is characterized by long periods of nutritional deprivation punctuated by short periods that allow fast growth, a feature that is commonly referred to as the feast-or-famine lifestyle. ...

Stationary phase in gram-negative bacteria.
Navarro Llorens JM, Tormo A, Martínez-García E. Navarro Llorens JM, et al. Among authors: tormo a. FEMS Microbiol Rev. 2010 Jul;34(4):476-95. doi: 10.1111/j.1574-6976.2010.00213.x. Epub 2010 Feb 6. FEMS Microbiol Rev. 2010. PMID: 20236330 Review.
As a consequence of prolonged starvation, certain bacterial species enter a dynamic nonproliferative state in which continuous cycles of growth and death occur until 'better times' come (restoration of favourable growth conditions). ...The entrance to the stationary …

Further studies on RpoS in enterobacteria: identification of rpoS in Enterobacter cloacae and Kluyvera cryocrescens.
Martínez-García E, Tormo A, Navarro-Llorens JM. Martínez-García E, et al. Among authors: tormo a. Arch Microbiol. 2001 Jun;175(6):395-404. doi: 10.1007/s002030100277. Arch Microbiol. 2001. PMID: 11491080
Many enterobacteria are opportunistic human pathogens and their ability to survive in a changing environment could be an essential step for their virulence. ...The rpoS gene from E. cloacae and from K. cryocrescens was cloned and sequenced and a mutant allele was co …

Sigma s regulates pLS1 maintenance in stationary-phase Escherichia coli.
Espinosa-Urgel M, Chamizo C, Tormo A. Espinosa-Urgel M, et al. Among authors: tormo a. FEMS Microbiol Lett. 1996 Jan 1;135(1):45-50. doi: 10.1111/j.1574-6968.1996.tb07964.x. FEMS Microbiol Lett. 1996. PMID: 8598276
Our results indicate that pLS1 is less stable and has a lower number of copies in a rpoS mutant than in a wild-type strain during stationary phase. ...

Microbial competition: Escherichia coli mutants that take over stationary phase cultures.
Zambrano MM, Siegele DA, Almirón M, Tormo A, Kolter R. Zambrano MM, et al. Among authors: tormo a. Science. 1993 Mar 19;259(5102):1757-60. doi: 10.1126/science.7681219. Science. 1993. PMID: 7681219
This phenotype was conferred by mutations in rpoS, which encodes a putative stationary phase-specific sigma factor. These rapid population shifts have implications for the studies of microbial evolution and ecology....

Role of the Escherichia coli SurA protein in stationary-phase survival.
Lazar SW, Almirón M, Tormo A, Kolter R. Lazar SW, et al. Among authors: tormo a. J Bacteriol. 1998 Nov;180(21):5704-11. doi: 10.1128/JB.180.21.5704-5711.1998. J Bacteriol. 1998. PMID: 9791122 Free PMC article.
SurA is a periplasmic peptidyl-prolyl isomerase required for the efficient folding of extracytoplasmic proteins. Although the surA gene had been identified in a screen for mutants that failed to survive in stationary phase, the role played by SurA in stationary-phas …

Stationary-phase-inducible "gearbox" promoters: differential effects of katF mutations and role of sigma 70.
Bohannon DE, Connell N, Keener J, Tormo A, Espinosa-Urgel M, Zambrano MM, Kolter R. Bohannon DE, et al. Among authors: tormo a. J Bacteriol. 1991 Jul;173(14):4482-92. doi: 10.1128/jb.173.14.4482-4492.1991. J Bacteriol. 1991. PMID: 1906064 Free PMC article.
A group of stationary-phase-inducible promoters, known as "gearbox" promoter, display a characteristic sequence in the -10 region which differs greatly from the consensus sequence for sigma 70-dependent promoters. ...Bacteriol. 173: 4474-4481, 1991), experiments are

surA, an Escherichia coli gene essential for survival in stationary phase.
Tormo A, Almirón M, Kolter R. Tormo A, et al. J Bacteriol. 1990 Aug;172(8):4339-47. doi: 10.1128/jb.172.8.4339-4347.1990. J Bacteriol. 1990. PMID: 2165476 Free PMC article.
The mutation (surA1) caused by insertion of a mini-Tn10 element defined a new gene located near 1 min on the E. coli chromosome. It was located directly upstream of pdxA and formed part of a complex operon. Evidence is presented supporting the interpretation …

The DNA sequence of Enterobacter cloacae CETC960 shows a 2.6-kb insertion of unknown origin between rpoS and slyA. This 2.6-kb sequence has also been detected in species of Salmonella and in Pseudomonas aeruginosa, but not in the same location. ...Our results support the i …
