They are also present in urinary-tract infections, burn victims, and patients on respirators with hospital-acquired pneumonia. Optimal temperature for growth is approximately 28ºC, although some species can grow at 4ºC or 41ºC. The temperature has been studied at 3 different values, and at a constant pH (7). 1. Pseudomonas fluorescens produces an antibiotic called Mupirocin. (4) Pseudomonas fluorescens PFO-1 is well adapted to the soil where it was first isolated in agricultural soil. All isolates were identified as Pseudomonas fluorescens (11). (2,4) The genome of Pseudomonas fluorescens PfO-1 has one chromosome with 6.43841 Mbp and 60.5% GC content. In accordance with previous results, the activity of extracellular proteases from Pseudomonas fluorescens MF0 is maximal at a growth temperature of 17.5 degrees C, well below the optimal growth temperature. By shedding light on variation in time as well as in space, long-term biogeographic studies can help us define organisms’ distribution patterns and understand their underlying drivers. Our results clearly indicate that inflammatory mediators are induced when the microorganism is grown at a lower temperature, while biofilm is formed only at 37 degrees C. The results presented are consistent with previous reports indicating P. fluorescens as an opportunistic pathogen and underscore the urgent need for further studies to better characterize the virulence of this microorganism. Several organic acids, amino acids, and uronic acids were shown to be attractants, whereas glucose and its oxidation products, gluconate and 2-ketogluconate, elicited no detectable response. Pseudomonas fluorescens produces hydrogen cyanide and the siderophores pyocheline and pyoverdine which it uses to outcompete with many pathogenic bacteria for iron necessary for growth and suppress pathogens in the rhizosphere. Diseases from Rhizoctonia solani and Pythium ultimum that affect cotton plants are inhibited by this strain. P. putida is distinguished from P. fluorescens (Bossis et al.

Strain Pf-5 possess many extracellular hydrolytic enzymes that degrade polymers found in soil as well as hydrolases used on plant-derived carbohydrates. The resuscitation ability of Pseudomonas populations exposed to absence of nutrients and nonoptimum temperature (37 °C) was tested in the presence of nutrients (10% LB), absence of oxidative stress (10% LB supplemented with catalase) and incubation at optimum growth temperature (27 °C). Pseudomonas fluorescens are Gram-negative rod shaped bacteria that inhabit soil, plants, and water surfaces. Their resistance to antibiotics have made them dangerous pathogens. Antibiotics such as pyrrolnitrin, pyoluteorin, and 2,4-diacetylphloroglucinol that inhibit phytopathogen growth are produced by Pseudomonas fluorescens Pf-5. Pseudomonas fluorescens grows at an optimum temperature of 25 degrees Celsius but can also survive in temperatures as low as 0 degrees C. Therefore, it is rarely pathogenic in humans making it an effective microbe for treating crops since it is not able to survive in the human body. Most species can’t tolerate acid conditions (pH 4.5 or lower) . (4), One of many byproducts of plant cells include active oxygen such as superoxide which are toxic to microbes. This explains why the fluorescent pigment is only produced when iron concentrations are low. These microbes live in diverse environments including soils, marshes, as well as plant and animal tissues, which show their nutritional versatility. 2007. 4. The presence of these enzymes contribute to Pseudomonas fluorescens’s tolerance to oxidative stress. Virulence Attributes and Host Response Assays for Determining Pathogenic Potential of Pseudomonas Strains Used in Biotechnology. "Complete genome sequence of the plant commensal, Stover, C.K., Pham, X.Q., Erwin, A.L. There are other species of Pseudomonas that are pathogens. These patients had been treated in the chemotherapy room and had begun exhibiting symptoms such as fevers and chills. 6. http://www.ebi.ac.uk/2can/genomes/bacteria/Pseudomonas_syringae.html. It contains 87 RNAs and 6137 proteins. In this study we examined the ability of P. fluorescens, grown at 28 degrees C or at 37 degrees C, to adhere to cultured human A549 pulmonary cells and to form biofilm. Pseudomonas fluorescens are Gram-negative rod shaped bacteria that inhabit soil, plants, and water surfaces. 12. MRSA was identified in the burn wounds of all forty-five children before the treatment began. (7), 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase from Pseudomonas fluorescens was studied against saline stress in groundnut (Arachis hypogea) plants under in vitro and field conditions in which four plant growth-promoting rhizobacteria (PGPR) were used. The ability of P. fluorescens to induce expression of proinflammatory cytokines, beta-defensin 2 and the intercellular adhesion molecule-1 was also investigated. 5.7% of its genome contributes to secondary metabolism which is the largest of the pseudomonas. The aim of this paper was to determine whether the quality of formulated Pseudomonas fluorescens Pf153 can be influenced by changes in fermentation conditions. Pseudomonas fluorescens can induce and divert the human β-defensin-2 secretion in intestinal epithelial cells to enhance its virulence. Environmental isolates of P. fluorescens have an optimal temperature growth range of 25 to 30°C and are not virulent to human cells, but certain strains of P. fluorescens isolated from clinical samples have a higher permissive growth range, up to 37°C, and show increased virulence against human cells (53, 57 – 59). It prefers to grow within the temperature range of 25 - 30° C. Unlike other saccharolytic bacteria, P. fluorescens is not capable of hydrolyzing sugar for energy production. A study was conducted with forty-five children who had MRSA infected burn wounds. The results of the experiment showed that at high concentrations all five strains of Pseudomonas fluorescens tested inhibit spore production by pathogenic plant fungus. It is an obligate aerobe, but certain strains are capable of using nitrate instead of oxygen as a final electron acceptor during cellular respiration.  |  Volume 20. p. 581-588. P. flurorescenscan produce certain enzymes such as heat stable lipases and proteases which are involeved in the spoiling of milk (10). Pseudomonas also use siderophores from other microorganism to obtain iron which increases their survival in iron-limited environments. It has also been found to be an opportunistic pathogen in immune compromised fish like Koi which are commonly kept in backyard garden ponds. Nature Biotechnology. (4)Pseudomonas fluorescens produces viscosin which is a peptidolipid that enhances antivirality. Volume 36, p. 2914-2917. A Microbial Biorealm page on the genus Pseudomonas fluorescens, Bacteria; Proteobacteria; Gammaproteobacteria; Pseudomonadales; Pseudomonadaceae. Based on the nature of its growth, pseudomonas fluorescens is categorized under obligate aerobes, meaning that oxygen is necessary for its survival. The significance of these organisms have increased because of their ability to degrade various pollutants and their use as bio-control against pathogens. (2) Sequencing the genome provided further information of its environmental interaction ands its metabolic capabilities, which can be used against agricultural disease control (1). There are 95 RNAs and 5736 proteins. The minimum temperatures allowing growth of the mutant strains increased to the same extent as their maximum temperatures. Soft-rot bacteria can grow and are active over a range of temperatures from 5 to 35°C. Pseudomonas cepacia, Achromobacter xylosoxidans, and Alcaligenes faecalis had a narrow range of growth temperature (28-37 C), and Pseudomonas fluorescens, Flavobacterium meningosepticum, and Moraxella grew most rapidly at 30 C. The above results are correlated fairly well with the incidence of clinical cases of infection. This page was last edited on 22 April 2011, at 19:06. Although Pseudomonas fluorescens typically has a low level of virulence, in 1997 four patients at the National Taiwan University Hospital developed Pseudomonas fluorescens bacteremia. Pseudomonas fluorescens is interesting and important to study because it produces a particular antibiotic (Mupirocin) which has been proven effective in treating certain kinds of skin, ear, and eye disorders (10).

However, as the material at our disposal could not work at a temperature inferior to 29°C, we could not try this range of temperatures. However, in the last few years, the isolation of P. fluorescens as the causative agent of nosocomial infections has rapidly increased. A series of heat tolerant mutants of Pseudomonas fluorescens were obtained which can grow at temperatures up to 54°C, in contrast to a maximum growth temperature of 37°C for the wild type. 2000; Chapalain et al. In spite of this constraint, it has recently been reported that the human physiological temperature does not appear to be a barrier for this microorganism. fluorescens phylogenetic lineage rather than in the P. aeruginosa lineage . biofilms is reported. Stover, C.K., Pham, X.Q., Erwin, A.L. At the end of the clinical study, MRSA was eliminated in all 59 wounds. The genome sequencing of P. fluorescens SBW25 is still in progress.(2). (4) Pseudomonas fluorescens PFO-1 is well adapted to the soil where it was first isolated in agricultural soil. The bacteria's degrading ability has been applied to pollutants such as styrene, TNT and, polycyclic aromatic hydrocarbons. Due to its nature of siderophore overproduction, experiments were performed to investigate the relationship between siderophores production and its growth. Results showed improvement in yield even in the presence of saline. 2016 May;38(5):787-92. doi: 10.1007/s10529-016-2047-x. Some strains can use NO3 instead of O2 as the electron acceptor. : … Whereas the survival of E. coli had an inverse relationship with temperature, whereas for P. fluorescens a direct relationship between temperature and T 90 values was only established in the range 5–15 °C, with an inverse relationship at higher temperatures.
