- Fission at low excitation energy, is a process in which both macroscopic and microscopic aspects are involved. Some features in the total kinetic energy and in the N/Z distributions of the fragments, commonly associated with shell effects, came out in a series of recent experiments with high excitation energy fusion fission reactions in inverse kinematics. In the latest experiment of this campaign, a study of high-energy fission and quasi-fission between a U-238 beam and a series of light targets was carried out by using the aforementioned technique, in order to probe the role of the shell structure in these processes.

- We fabricate a square planar photonic crystal (PC) from carbon nanofibres (CNFs) using e-beam lithography and chemical vapour deposition and investigate the optical properties of this system. The system exhibit diffraction that is well described by diffraction theory. We measure the intensity of the (-1,0) and (-1,-1) diffraction spots as functions of angle of incidence. The radiation diagram obtained can be explained by interference between different diffraction beams. We observe a polarisation dependence of the intensity. In conclusion we suggest future applications of these structures.

- Carbon nanofibers (CNFs) are used as components of planar photonic crystals. Square and rectangular lattices and random patterns of vertically aligned CNFs were fabricated and their properties studied using ellipsometry. We show that detailed information such as symmetry directions and the band structure of these novel materials can be extracted from considerations of the polarization state in the specular beam. The refractive index of the individual nanofibers was found to be n(CNF) = 4.1.

- Members of the genus Flavobacterium are widely distributed microorganisms that can be recovered from a wide variety of environments. There has been an increase in the number of species isolated from fish or fish farm environments, some of thempossibly associated with disease. Fourteen Flavobacterium-like isolates recovered from gills, surface of eggs and liver of rainbow trout were characterized by a polyphasic study that included a deep phenotypic, chemotaxonomic, genotypic and phylogenetic analysis. Comparative 16S rRNA gene analysis revealed that isolates represented three separate phylogenetic groups (A-C) within the genus Flavobacterium. Further genotypic and phenotypic data demonstrated that they represent three novel species of the genus Flavobacterium for which the names Flavobacterium collinsii, Flavobacterium branchiarum and Flavobacterium branchiicola are proposed. Most isolates of the three species were collected from gills indicating that they are probably commensal organisms that are able to colonize this tissue. However, some strains were recovered from the liver of two different trout, suggesting their ability to infect trout. (C) 2013 Elsevier B. V. All rights reserved.

- Genotypic and phenotypic analyses were performed on five Gram-negative, catalase and oxidase-positive, rod-shaped bacteria isolated from the gill and liver of four rainbow trout. Studies based on comparative 16S rRNA gene sequence analysis showed that the five new isolates shared 99.8-100% sequence similarity and that they belong to the genus Chryseobacterium. The nearest phylogenetic neighbours of the strain 701B-08(T) were Chryseobacterium ureilyticum F-Fue-04IIIaaaa(T) (99.1% 16S rRNA gene sequence similarity) and Chryseobacterium joosteii LMG 18212(T) (98.6%). DNA-DNA hybridization values between the five isolates were 91-99% and ranged from 2 to 53% between strain 701B-08(T) and the type strains of phylogenetically closely related species of Chryseobacterium. Strain 701B-08(T) had a DNA G+C content of 36.3 mol%, the major fatty acids were iso-C(15:0), iso-C(17:1)ω9c, C(16:1)ω6c and iso-C(17:0) 3-OH and the predominant respiratory quinone was MK-6. The novel isolates were distinguished from related Chryseobacterium species by physiological and biochemical tests. The genotypic and phenotypic properties of the isolates from rainbow trout suggest their classification as representatives of a novel species of the genus Chryseobacterium, for which the name Chryseobacterium oncorhynchi sp. nov. is proposed. The type strain is 701B-08(T) (=CECT 7794(T)=CCUG 60105(T)).

- Three pale-orange bacteria (strains 1083-08, 1084-08(T) and 1095B-08) were isolated from diseased rainbow trout. The isolates were Gram-staining-negative, catalase- and oxidase-positive, rod-shaped cells. Analyses of their 16S rRNA gene sequences confirmed their adscription to the genus Chryseobacterium. The three isolates shared 100% 16S rRNA gene sequence similarity and 98.5% similarity with Chryseobacterium indologenes CCUG 14556(T), being the closest phylogenetically related species. Genomic DNA-DNA hybridization similarity values between the three isolates were 94-100% and 2-39% between strain 1084-08(T) and the type strains of other related Chryseobacterium species, confirming that the isolates represent a novel species within the genus Chryseobacterium. The DNA G+C content of the species was 33.6-36.1mol%. The predominant respiratory quinone of strain 1084-08(T) was MK-6 and the major fatty acids were iso-C(15:0), iso-C(17:1)ω9c, iso-C(17:0) 3-OH and C(16:1)ω6c. The isolates were distinguished from related Chryseobacterium species by a number of phenotypic properties. Based on the phenotypic, genotypic and phylogenetic findings, it is proposed that the new isolates from rainbow trout be classified as a new species of the genus Chryseobacterium, with the name of Chryseobacterium tructae sp. nov. The type strain is 1084-08(T) (=CECT 7798(T)=CCUG 60111(T)).

Tidskriftsartikel (refereegranskat)abstract
- Eighteen isolates of a Gram-negative, catalase and oxidase-positive, rod-shaped bacterium, recovered from diseased rainbow trout (Oncorhynchus mykiss), were characterized, using a polyphasic taxonomic approach. Studies based on comparative 16S rRNA gene sequence analysis showed that that the eighteen new isolates shared 99.2-100% sequence similarities. Phylogenetic analysis revealed that isolates from trout belonged to the genus Flavobacterium, showing the highest sequence similarities to F. chungangense (98.6%), F. frigidimaris (98.1%), F. hercynium (97.9%) and F. aquidurense (97.8%). DNA-DNA reassociation values between the trout isolates (exemplified by strain 631-08(T)) and five type strains of the most closely related Flavobacterium species exhibited less than 27% similarity. The G+C content of the genomic DNA was 33.0 mol%. The major respiratory quinone was observed to be menaquinone 6 (MK-6) and iso-C(15:0), C(15:0) and C(16:1) ω7c the predominant fatty acids. The polar lipid profile of strain 631-08(T) consisted of phosphatidylethanolamine, unknown aminolipids AL1 and AL3, lipids L1, L2, L3 and L4 and phospholipid PL1. The novel isolates were differentiated from related Flavobacterium species by physiological and biochemical tests. On the basis of the evidence from this polyphasic study, it is proposed that the isolates from rainbow trout be classified as a new species of the genus Flavobacterium, Flavobacterium oncorhynchi sp. nov. The type strain is 631-08(T) (= CECT 7678(T) = CCUG 59446(T)).

- Five strains (1126-1H-08(T), 51B-09, 986-08, 1084B-08 and 424-08) were isolated from diseased rainbow trout. Cells were Gram-negative rods, 0.7 mu m wide and 3 mu m long, non-endospore-forming, catalase and oxidase positive. Colonies were circular, yellow-pigmented, smooth and entire on TGE agar after 72 hours incubation at 25 degrees C. They grew in a temperature range between 15 degrees C to 30 degrees C, but they did not grow at 37 degrees Cor 42 degrees C. Based on 16S rRNA gene sequence analysis, the isolates belonged to the genus Flavobacterium. Strain 1126-1H-08(T) exhibited the highest levels of similarity with Flavobacterium oncorhynchi CECT 7678(T) and Flavobacterium pectinovorum DSM 6368(T) (98.5% and 97.9% sequence similarity, respectively). DNA-DNA hybridization values were 87 to 99% among the five isolates and ranged from 21 to 48% between strain 1126-1H-08(T), selected as a representative isolate, and the type strains of Flavobacterium oncorhynchi CECT 7678(T) and other phylogenetic related Flavobacterium species. The DNA G+C content of strain 1126-1H-08(T) was 33.2 mol%. The predominant respiratory quinone was MK-6 and the major fatty acids were iso-C-15:0 and C-15:0. These data were similar to those reported for Flavobacterium species. Several physiological and biochemical tests differentiated the novel bacterial strains from related Flavobacterium species. Phylogenetic, genetic and phenotypic data indicate that these strains represent a new species of the genus Flavobacterium, for which the name Flavobacterium plurextorum sp. nov. was proposed. The type strain is 1126-1H-08(T) (=CECT 7844(T) = CCUG 60112(T)).

- Four Gram-staining-negative, catalase- and oxidase-positive, pale-orange pigmented bacterial strains (435-08(T), 47B-3-09, 412R-09(T) and 60B-3-09) were isolated from diseased rainbow trout. Analysis of their 16S rRNA gene sequences suggested their adscription to the genus Flavobacterium. Strains formed two phylogenetic groups represented by strains 435-08(T) and 47B-3-09 (group A), and strains 412R-09(T) and 60B-3-09 (group B) displaying 16S rRNA sequence similarities greater than 99.8-99.9% within their respective groups. Strain 435-08(T) exhibited the highest levels of similarity with Flavobacterium aquidurense WB-1.1.56(T) (98.6% sequence similarity) and strain 412R-09(T) with Flavobacterium frigidimaris KUC-1(T) and Flavobacterium aquidurense WB-1.1.56(T) (98.9% and 98.6% sequence similarity, respectively). DNA DNA hybridization studies showed low levels of relatedness between strain 435-08(T) and strain 412R-09(T) and between both strains and the most closely related species of the genus Flavobacterium. The genomic DNA G+C contents of strains 435-08(T) and 412R-09(T) were 36.2 and 34.3 mol%, respectively. The predominant respiratory quinone of both strains was MK-6 and the major fatty acids were iso-C-15:0, C-16:1 omega 7c and C-15:0. The two groups of strains could be distinguished from each other and from related species of the genus Flavobacterium by a number of phenotypic properties. Phylogenetic, genotypic and phenotypic evidence indicated that strains of groups A and B represent two novel species of the genus Flavobacterium, for which the names Flavobacterium tructae sp. nov. (type strain 435-08(T)=CECT 7791(T)=CCUG 60100(T)) and Flavobacterium piscis sp. nov. (type strain 412R-09(T)=CECT 7911(T)=CCUG 60099(T)) are proposed.
