Abstract:

Hafnia and zirconia gels were prepared by drying hafnyl or zirconyl acetate solutions. Hafnia and zirconia gels contain both hydroxyl group and bidentate acetates which are directly bonded to the metal ions. Thermal decomposition and crystallization behavior of the gels were investigated through XRD, FT-IR, and TEM. Hafnium-containing gels crystallized directly into stable monoclinic hafnia around 500–540 °C, while zirconium-containing gels first formed metastable tetragonal zirconia around 450 °C. The dissimilar crystallization behavior of the gels into metastable, tetragonal zirconia or into stable, monoclinic hafnia can be explained through the difference in free-energy changes of the tetragonal-to-monoclinic phase transformation.

Abstract:

SUMMARY The genus Hafnia, a member of the family Enterobacteriaceae, consists of gram-negative bacteria that are occasionally implicated in both intestinal and extraintestinal infections in humans. Despite the fact that the genus currently contains only a single species (H. alvei), more extensive phylogenetic depth (two or more species) is apparent based upon DNA relatedness and 16S rRNA gene sequencing studies. Hafnia causes a variety of systemic infections, including septicemia and pneumonia; however, its role as a gastrointestinal pathogen is controversial. Many of the data supporting a role for hafniae as enteric pathogens were incorrectly attributed to this genus rather than to the actual pathogen, Escherichia albertii. There are numerous gaps in our understanding of this genus, including ecologic habitats and population genetics, disease-producing role in animals, phenetic and genetic methods useful in distinguishing genomospecies within the H. alvei complex, and bona fide pathogenicity factors.

Abstract:

The results of elaborating a method for the synthesis of zirconia and hafnia doped by rare earths (yttrium, erbium and scandium) by using low-hydrated hydroxides of zirconium and hafnium as precursors are reported. The low-hydrated zirconium and hafnium hydroxides were prepared using the heterophase reaction. The physicochemical properties (including sorption properties) of low-hydrated zirconium and hafnium hydroxides ZrxHf1-x(OH)3÷1O0.5÷1.5·0.9÷2.9H2Owere studied. The scheme of thermal decomposition of low-hydrated hydroxides in air was determined. The sorption properties of the low-hydrated hafnium hydroxide are less pronounced owing to the lower amount of sorption centers, in this case, hydroxo and aqua groups. The sequence of stages of thermal decomposition of rare earth acetates was elucidated. Single-phase zirconia and hafnia doped by rare earths (yttrium, erbium and scandium) were obtained. The parameters of the elementary lattice were calculated for each phase. It was established that the stabilization of zirconium dioxide with yttria leads to the formation of interstitial solid solutions based on tetragonal zirconia (in the case of the composition Y2O3×4ZrO2 - cubic modification), with erbium oxide - interstitial solid solutions based on cubic zirconia; with scandium oxide - solid solutions based on tetragonal zirconia. The article presents the results of measuring electrical conductivity.

Abstract:

A psychrotolerant, Gram-stain-negative, motile, aerobic, peritrichous bacterium, strain DJC1-1T, was isolated from Lake Dajiaco, Tibetan Plateau, China. The strain was negative for citrate utilization, lipase activity and α-glucosidase, but positive for the Voges–Proskauer reaction and N-acetyl-β-glucosaminidase. 16S rRNA gene sequence analysis indicated that Hafnia paralvei ATCC 29927T, Hafnia alvei ATCC 13337T, Serratia grimesii DSM 30063T and Serratia plymuthica DSM 4540T were the closest relatives of strain DJC1-1T, with similarities of 97.76, 96.80, 97.71 and 97.58 %, respectively. The DNA G+C content of strain DJC1-1T was 53.9 mol%. The predominant fatty acids were C16 : 0 and C17 : 0 cyclo. Based on these characteristics, strain DJC1-1T can be assigned to the genus Hafnia . In DNA–DNA hybridization tests, strain DJC1-1T shared 50.6, 35.1, 36.5 and 18.1 % DNA–DNA relatedness with the type strains of H. paralvei , H. alvei , S. grimesii and S. plymuthica , respectively. The growth temperature ranged from 0 to 40 °C, with optimum growth at 15 °C. Physiological and biochemical tests differentiated strain DJC1-1T from the type strains of recognized species of the genus Hafnia . Therefore, strain DJC1-1T is identified as representing a novel species of the genus Hafnia, for which the name Hafnia psychrotolerans sp. nov. is proposed. The type strain is DJC1-1T ( = JCM 30077T = CGMCC1.12806T).

Abstract:

Hafnium carbide powder was synthesized by sol-gel polycondensation of hafnium chloride with citric acid. The starting materials were dissolved in water and mixed homogeneously on a hot plate until a precomposite gel was formed. Pyrolysis of the obtained gel resulted in formation of monoclinic hafnia and amorphous carbon, which after subsequent heat treatment transformed into hafnium carbide. Materials were analyzed by means of X-ray diffraction and electron microscopy investigations. The results showed that the obtained carbide powder was composed of nearly equiaxed particles of narrow size distribution. The obtained hafnium carbide powder was densified via spark plasma sintering (SPS) at 1950 oC using molybdenun silicide as sintering additive. Microstructure and mechanical properties of the obtained hafnium carbide ceramics were investigated.

Abstract:

Syftet med denna magisteruppsats är att gå vidare med resultat från en kandidatuppsats (Westling, 2013) gällande opastöriserade franska mögel- och kittostar genom att undersöka vilka Enterobacteriaceae-arter som ett urval av de analyserade ostarna innehöll. API 20E används som identifieringssystem. Tre Enterobacteriaceae-arter gav acceptabel till utmärkt identifiering av 40 analyserade isolat från de fyra ostarna, nämligen Hafnia alvei, Escherichia coli och Klebsiella pneumoniae. Inga skillnader mellan de identifierade arterna vad gäller inverkan på smak- och doftupplevelser hos opastöriserade franska mögel- och kittostar gick att urskilja med tillgänglig sensorisk data från kandidatuppsatsen (Westling, 2013). Utifrån denna magisteruppsats räcker det inte med att dofta på ostarna för att säkerställa hygienisk kvalitet, ytterligare undersökningar behövs för att kunna identifiera vilka Enterobacteriaceae-arter de innehåller. Däremot skulle en förstudie i form av en sensorisk bedömning av opastöriserade mögel- och kittostar kunna påvisa om ett högt antal Enterobacteriaceae föreligger, vilka vid konsumtion kan vara sjukdomsframkallande.

Abstract:

L’objectif de ce travail était de mieux comprendre les mécanismes moléculaires de l’adaptation microbienne à l’environnement fromager par des approches de génomique fonctionnelle via le modèle de Brevibacterium, un genre bactérien largement utilisé en technologie fromagère, mais dont l’implantation est parfois difficile à maîtriser.L’analyse génomique comparative de 23 souches de Brevibacterium, dont 12 issues de fromages, a révélé des différences en déterminants génétiques impliqués dans la capacité à croître à la surface du fromage. Parmi ces différences, plusieurs sont corrélées à la phylogénie des souches, et d’autres résultent de transferts horizontaux, notamment dans le cas des gènes liés à l’acquisition du fer et à la biosynthèse de bactériocines. Nous avons identifié des îlots génomiques correspondant à des transferts de gènes d’acquisition du fer entre des souches fromagères de Brevibacterium et des bactéries d’affinage appartenant à d’autres genres. Nous avons également mis en évidence un transposon conjugatif codant pour la synthèse de bactériocines présent chez des souches de Brevibacterium d'origine fromagère mais aussi chez une souche fromagère du genre Corynebacterium.L’étude fonctionnelle des interactions biotiques entre Brevibacterium et Hafnia alvei, une autre bactérie d’affinage du fromage, a été menée dans un modèle fromager développé au cours de ce travail. En couplant des analyses microbiologiques, biochimiques et transcriptomiques (RNA-seq), nous avons mis en évidence l’existence de différents mécanismes d’interaction entre ces bactéries. Ceux-ci concernent notamment l’acquisition du fer, la protéolyse, la lipolyse, le métabolisme soufré et le catabolisme du D-galactonate. Nos résultats suggèrent que dans la relation mutualiste observée entre certaines souches de Brevibacterium et H. alvei, cette dernière sécrète des sidérophores qui sont utilisés par Brevibacterium pour capter le fer plus efficacement, stimulant ainsi sa croissance. En contrepartie, Brevibacterium sécrète des lipases et des protéases qui dégradent les caséines et triglycérides du fromage en constituants énergétiques favorisant la croissance de H. alvei. Ce type d’interaction est intéressant à considérer pour la formulation des ferments d'affinage car il en résulte une meilleure capacité de tous les partenaires à coloniser le fromage, et ainsi à générer les propriétés technologiques recherchées
The objective of this study was to better understand the molecular mechanisms of microbial adaptation to the cheese habitat by functional genomic approaches using Brevibacterium as a model microorganism. This bacterium is widely used for the manufacturing of cheese but its growth on the cheese surface is sometimes difficult to control.Comparative genomic analysis of 23 Brevibacterium strains, including 12 strains isolated from cheeses, revealed differences in genetic determinants involved in the growth on the cheese surface. Some of them are correlated to strain phylogeny and others are the result of gene transfers, especially those involved in iron acquisition and bacteriocin biosynthesis. We identified genomic islands corresponding to transfers of genes involved in iron acquisition between cheese-associated Brevibacterium strains and cheese-associated strains belonging to other genera. We also detected a conjugative transposon encoding bacteriocin production, which is present in cheese-associated Brevibacterium strains as well as in a cheese-associated Corynebacterium strain.Functional study of biotic interactions between Brevibacterium and Hafnia alvei, another cheese-ripening bacterium, was performed in a model cheese developed in this study. By coupling microbial, biochemical and transcriptomic (RNA-seq) analyses, we revealed several interaction mechanisms between these bacteria. These concern, in particular, iron acquisition, proteolysis, lipolysis, sulfur metabolism and D-galactonate catabolism. Our findings suggest that in the mutualistic relationship between some Brevibacterium strains and H. alvei, the latter stimulates Brevibacterium growth by the secretion of siderophores, which can be used by Brevibacterium to capture iron more efficiently. In return, Brevibacterium secretes lipases and proteases, which degrade cheese caseins and triglycerides into energetic substrates that stimulate H. alvei growth. This type of interaction is interesting to consider in the formulation of ripening cultures because it results in a better ability of all partners to colonize the cheese, and thus to generate the desired technological properties

Quando em alta densidade populacional, muitas bactérias são capazes de coordenar a expressão de genes via produção e recepção de sinais químicos, por meio de mecanismo denominado quorum sensing. O objetivo deste trabalho foi obter mutantes HalI - das estirpes psicrotróficas isoladas do leite cru refrigerado, 068 e 071 de Hafnia alvei e 067 de Enterobacter cloacae. O gene halI codifica a sintase responsável pela produção de acil homoserina lactonas (AHLs) que são as moléculas sinalizadoras de quorum sensing em H. alvei e E. cloacae. Para obtenção dos mutantes, foi utilizado o vetor suicida pGP704, onde foi clonado o gene halI. Em seguida este gene foi interrompido com o gene que codifica a proteína gentamicina- 3-acetiltransferase, que confere resistência ao antibiótico gentamicina e o plasmídeo foi denominado pGP704halI068::Gm. A transformação das estirpes psicrotróficas com esse vetor resultou em transformantes resistentes a 25 μg mL -1 de gentamicina, mas que ainda produziam AHL, constatada por meio da indução da estirpe monitora de AHL, Chromobacterium violaceum CV 026. A inativação da expressão do gene halI no DNA cromossômico foi obtida após nova transformação desses transformantes com o vetor pUT::Tn5, pertencente ao mesmo grupo de compatibilidade de pGP704. O uso deste sistema de incompatibilidade propiciou a seleção de estirpes onde ocorreu a recombinação homóloga entre o gene halI interrompido pelo gene que confere resistência a gentamicina com o gene halI presente no DNA cromossômico. A confirmação da recombinação do gene halI inativado e clonado no plasmideo com o gene halI cromossômico, foi feita selecionando-se os transformantes em ágar Luria Bertani contendo 50 μg mL -1 de canamicina e gentamicina. Por ensaio de indução de C. violaceum CV026, foi confirmado que os transformantes resistentes a canamicina e gentamicina não induziram a produção do pigmento violaceína pela estirpe monitora. A inativação do gene halI no cromossoma torna essas estirpes ferramentas importantes para elucidação da regulação da expressão de genes pelo mecanismo de quorum sensing.
When population density is high, several bacteria are able to coordinate gene expression by production and reception of chemical signals by means of a mechanism called quorum sensing. The scope of this work was to produce HalI - mutants from psychotrophic bacterias found in fresh cooled milk, 068 and 071 of Hafnia alvei and 067 of Enterobacter cloacae. The halI gene encondes the synthase responsible for the production of acyl-homoserine lactones (AHLs) which are the signaling molecules of quorum sensing for H. alvei and E. cloacae. In order to produce the mutants, it was used the suicide vector pGP704, where the halI gene was cloned. After that, this gene was interrupted with a gene that encodes the protein gentamicin 3-acetyltransferase, responsible for giving resistance to the gentamicin antibiotic. This vector was called pGP704halI068::Gm. The transformation of psychotrophic strain with such vector resulted in transformants cells resistant to 25 μg mL -1 of gentamicin, but they would still produce AHL. AHL production was confirmed by the induction of the monitored strain of AHL, Chromobacterium violaceum CV 026. Expression inactivation of the hall gene in the chromosomic DNA was achieved after new transformation of former transformants with the pUT::Tn5 vector, which belong to the same compatible group of pGP704. The use of this system of incompatibility provided the selection of strain that showed homologous recombination between the hall gene interrupted by the gene that affords resistance to gentamicin and the hall gene of the present chromosomal DNA. Recombination assurance of the halI gene inactivated and cloned in the plasmidium with the halI chromosomic gene was done by selecting the transformants in Luria- Bertani agar containing 50 μg mL -1 of kanamicyn and gentamicin. By means of an induction trial of C. violaceum CV026, it was confirmed that the transformants resistant to kanamicyn and gentamicin did not induced the production of the violacein pigment by the strain being monitored. Inactivation of the halI gene in the chromosome makes these strains important tools for elucidating gene expression regulation by the quorum sensing mechanism.
