| pseudomonas gessardii sp. nov. and pseudomonas migulae sp. nov., two new species isolated from natural mineral waters. | twenty-five non-identified fluorescent pseudomonas strains isolated from natural mineral waters were previously clustered into three phenotypic subclusters, xiiib, xva and xvc. these strains were characterized genotypically in the present study. dna-dna hybridization results and dna base composition analysis revealed that these strains were members of two new species, for which the names pseudomonas gessardii sp. nov. (type strain cip 105469t) and pseudomonas migulae sp. nov. (type strain cip 10 ... | 1999 | 10555337 |
| pseudomonas grimontii sp. nov. | the vernacular name 'fluorescent pseudomonas group 97-514' was coined for a group of 43 strains isolated from two french natural mineral waters. all these strains were gram-negative, rod-shaped and motile by means of a single polar flagellum. they produced fluorescent pigment (pyoverdin) on king b medium, catalase and cytochrome oxidase. they were capable of respiratory but not fermentative metabolism. they were not able to accumulate poly-beta-hydroxybutyrate and possessed an arginine dihydrola ... | 2002 | 12361251 |
| production of a novel extracellular acidic lipase from pseudomonas gessardii using slaughterhouse waste as a substrate. | an isolate exhibiting high extracellular lipolytic activity was identified as pseudomonas gessardii by 16s rdna gene sequence analysis. the slaughterhouse waste, goat tallow, was used as a lipid substrate for the production of acidic lipase by p. gessardii. the maximum lipase activity of 156 u/ml was observed at an acidic ph of 3.5 and at 0.31 g substrate concentration. the purification steps resulted in the isolation of acidic lipase with a specific activity of 1,473 u/mg and a molecular weight ... | 2010 | 20204455 |
| isolation, identification and characterization of a new lipolytic pseudomonas sp., strain ahd-1, from tunisian soil. | a novel, lipid-degrading bacterium (strain ahd-1) was isolated from soil regularly contaminated with washing-machine wastewater in sfax, tunisia. when this strain was grown in a medium containing 2% triacylglycerol, the hydrolysis products were found to be diacylglycerols, monoacylglycerols and free fatty acids. this strain was an aerobic, mesophilic, gram-negative, motile, non-sporulating bacterium, capable of growing optimally at ph 7 and 27 degrees c. the predominant fatty acids were found to ... | 2010 | 20232682 |
| influence of storage conditions on the growth of pseudomonas species in refrigerated raw milk. | the refrigerated storage of raw milk throughout the dairy chain prior to heat treatment creates selective conditions for growth of psychrotolerant bacteria. these bacteria, mainly belonging to the genus pseudomonas, are capable of producing thermoresistant extracellular proteases and lipases, which can cause spoilage and structural defects in pasteurized and ultra-high-temperature-treated milk (products). to map the influence of refrigerated storage on the growth of these pseudomonads, milk samp ... | 2010 | 21115713 |

| population structure and diversity of phenazine-1-carboxylic acid producing fluorescent pseudomonas spp. from dryland cereal fields of central washington state (usa). | certain strains of the rhizosphere bacterium pseudomonas fluorescens contain the phenazine biosynthesis operon (phzabcdefg) and produce redox-active phenazine antibiotics that suppress a wide variety of soilborne plant pathogens. in 2007 and 2008, we isolated 412 phenazine-producing (phz(+)) fluorescent pseudomonas strains from roots of dryland wheat and barley grown in the low-precipitation region (<350 mm annual precipitation) of central washington state. based on results of box-pcr genomic fi ... | 2012 | 22383119 |
| low bacterial diversity and high labile organic matter concentrations in the sediments of the medee deep-sea hypersaline anoxic basin. | studies in the center and margin of the medee basin, a mediterranean deep-sea hypersaline anoxic basin, and at a reference site during penelope cruise (2007), revealed the existence of a 7 m-thick halocline, with high salinity (328 psu), and high sedimentary organic carbon and biopolymer concentrations. the 194 16s rrna sequences retrieved were grouped into 118 unique phylotypes. pseudomonas gessardii, dominated in the center, while 33 phylotypes were detected at the margin and 73 at the referen ... | 2012 | 22504432 |
| microbial induced lipoprotein biosurfactant from slaughterhouse lipid waste and its application to the removal of metal ions from aqueous solution. | this study aims at demonstrating the production of lipoprotein biosurfactant from pseudomonas gessardii using goat tallow, a slaughterhouse lipid waste, as the substrate and its application to the removal of metal ions from aqueous solution. the maximum bio-transformation of goat tallow into biosurfactant occurred at 48 h. the mass of the lipoprotein biosurfactant produced was 2.03 g/g of goat tallow. the biosurfactant was clearly characterized by surface tension, critical micelle concentration, ... | 2012 | 22592059 |
| pseudomonas yamanorum sp. nov., a psychrotolerant bacterium isolated from a subantarctic environment. | a psychrotolerant strain, 8h1(t), was isolated from soil samples collected in isla de los estados, ushuaia, argentina. cells were gram-negative, aerobic, straight rods, occurring singly or in pairs, non-spore-forming and motile by means of two polar flagella. the isolate was able to grow in the range 4-35 °c, with optimum growth at 28 °c. the predominant cellular fatty acids were summed feature 3 (c16 : 1ω6c and/or c16 : 1ω7c), c16 : 0 and summed feature 8 (c18 : 1ω6c and/or c18 : 1ω7c). the pol ... | 2015 | 25385990 |
| pseudomonads rule degradation of polyaromatic hydrocarbons in aerated sediment. | given that the degradation of aromatic pollutants in anaerobic environments such as sediment is generally very slow, aeration could be an efficient bioremediation option. using stable isotope probing (sip) coupled with pyrosequencing analysis of 16s rrna genes, we identified naphthalene-utilizing populations in aerated polyaromatic hydrocarbon (pah)-polluted sediment. the results showed that naphthalene was metabolized at both 10 and 20°c following oxygen delivery, with increased degradation at ... | 2015 | 26635740 |
