Weon, B. M.,Je, J. H.,Hwu, Y.,Margaritondo, G. International Union of Crystallography 2008 Journal of synchrotron radiation Vol.15 No.6
<▼1><P>Microradiology with coherent X-rays is shown to be very effective in revealing interfaces in multiphase systems and in particular gas bubbles. Its use has been tested in the study of bubble colescence validating the results with a simple theoretical analysis based on mass conservation.</P></▼1><▼2><P>A quantitative application of microradiology with coherent X-rays to the real-time study of microbubble and microdroplet coalescence phenomena, with specific emphasis on the size relations in three-body events, is presented. The results illustrate the remarkable effectiveness of coherent X-ray imaging in delineating interfaces in multiphase systems, in accurately measuring their geometric properties and in monitoring their dynamics.</P></▼2>

<P>A Gram-stain-negative, aerobic, rod-shaped, non-motile and orange-coloured marine bacterium, YH207<SUP>T</SUP>, was isolated from a tidal flat at Yeongheung-do on the coast of the Yellow Sea, Korea. 16S rRNA gene sequence analysis revealed that strain YH207<SUP>T</SUP> was affiliated with the family <I>Cryomorphaceae</I> and showed highest similarity to <I>Brumimicrobium glaciale</I> IC156<SUP>T</SUP> (95.4 %). Growth was observed at 11–36 °C, at pH 6.5–10.0 and with 0.4–7.0 % NaCl. The predominant cellular fatty acids when grown at 20 °C were iso-C<SUB>15 : 0</SUB> (44.2 %), iso-C<SUB>15 : 1</SUB> G (34.3 %), iso-C<SUB>17 : 0</SUB> 3-OH (8.7 %) and summed feature 3 (comprising iso-C<SUB>15 : 0</SUB> 2-OH and/or C<SUB>16 : 1</SUB>ω7<I>c</I>; 2.3 %). The major respiratory quinone was MK-6. Phosphatidylethanolamine, phosphatidylglycerol, three unidentified lipids, three unidentified aminophospholipids, one unidentified phospholipid, four unidentified aminolipids and three unidentified glycolipids were identified as major polar lipids. The DNA G+C content was 34.3 mol%. On the basis of the data from our polyphasic taxonomic study, strain YH207<SUP>T</SUP> should be classified in a novel species in the genus <I>Brumimicrobium</I>, for which the name <I>Brumimicrobium mesophilum</I> sp. nov. is proposed. The type strain is YH207<SUP>T</SUP> ( = KCCM 42331<SUP>T</SUP> = JCM 14063<SUP>T</SUP>). Emended descriptions of the genus <I>Brumimicrobium</I> and <I>Brumimicrobium glaciale</I> Bowman <I>et al.</I> 2003 are also given.</P>

Lee, Geun-Hye,Rhee, Moon-Soo,Chang, Dong-Ho,Lee, Jonghwan,Kim, Seil,Yoon, Min Ho,Kim, Byoung-Chan International Union of Microbiological Societies 2013 International journal of systematic and evolutiona Vol.63 No.6
<P>A strictly anaerobic, Gram-negative, non-spore-forming bacterium, designated GH1<SUP>T</SUP>, was isolated from the rumen of Korean native cattle (HanWoo). Cells were straight to slightly curved rods (2.0–4.5 µm long) and were motile by peritrichous flagella. The isolate grew at 30–45 °C (optimum 40 °C), at pH 5.5–6.5 (optimum pH 6.0) and with up to 3.5 % (w/v) NaCl. Strain GH1<SUP>T</SUP> produced acid from <SMALL>d</SMALL>-glucose, <SMALL>d</SMALL>-ribose and <SMALL>d</SMALL>-xylose, with butyric acid being the major end product. The genomic DNA G+C content was 54.6 mol%. Based on comparative 16S rRNA gene sequence analysis, strain GH1<SUP>T</SUP> was most closely related to <I>Oscillibacter valericigenes</I> Sjm18-20<SUP>T</SUP> (97.3 % 16S rRNA gene sequence similarity). DNA–DNA hybridization between strain GH1<SUP>T</SUP> and <I>O. valericigenes</I> DSM 18026<SUP>T</SUP> showed 24 % reassociation. The major fatty acids were iso-C<SUB>13 : 0</SUB> (13.0 %), iso-C<SUB>15 : 0</SUB> (17.6 %), anteiso-C<SUB>15 : 0</SUB> (8.4 %) and C<SUB>14 : 0</SUB> (4.1 %), and the cellular fatty acid methyl esters as dimethylacetals (DMAs) were C<SUB>16 : 0</SUB> DMA (17.8 %), iso-C<SUB>15 : 0</SUB> DMA (15.2 %) and C<SUB>14 : 0</SUB> DMA (4.52 %). The cell-wall peptidoglycan of strain GH1<SUP>T</SUP> contained <I>meso</I>-diaminopimelic acid and the major cell-wall sugar was galactose. Based on 16S rRNA gene sequence similarity, phylogenetic analysis, DNA G+C content, DNA–DNA relatedness and distinct phenotypic characteristics, strain GH1<SUP>T</SUP> is classified in the genus <I>Oscillibacter</I> as a member of a novel species, for which the name <I>Oscillibacter</I> <I>ruminantium</I> sp. nov. is proposed. The type strain is GH1<SUP>T</SUP> ( = KCTC 15176<SUP>T</SUP> = NBRC 108824<SUP>T</SUP> = JCM 18333<SUP>T</SUP>).</P>

<P>A novel, Gram-stain-positive, non-motile, facultatively anaerobic, rod- or coccoid-shaped bacterium, designated strain ORY33<SUP>T</SUP>, was isolated from the gut of a camel cricket (<I>Diestrammena coreana</I>). The 16S rRNA gene sequence analysis showed that strain ORY33<SUP>T</SUP> belonged to the genus <I>Weissella</I>, with highest sequence similarity to <I>Weissella koreensis</I> S-5623<SUP>T</SUP> (97.7 %). The strain grew optimally at 30 °C and pH 7 in the presence of 0 % (w/v) NaCl. Catalase and oxidase activities were negative. The genomic DNA G+C content of strain ORY33<SUP>T</SUP> was 45.1 mol%. DNA–DNA hybridization values between strain ORY33<SUP>T</SUP> and closely related members of the genus <I>Weissella</I> were less than 27 %. The major fatty acids of strain ORY33<SUP>T</SUP> were C<SUB>18 : 1</SUB>ω9<I>c</I>, C<SUB>16 : 0</SUB> and C<SUB>14 : 0</SUB>. Based on these phenotypic, phylogenetic and genotypic analyses, strain ORY33<SUP>T</SUP> represents a novel species belonging to the genus <I>Weissella</I>, for which the name <I>Weissella</I> <I>diestrammenae</I> sp. nov. is proposed. The type strain is ORY33<SUP>T</SUP> ( = KACC 16890<SUP>T</SUP> = JCM 18559<SUP>T</SUP>).</P>

<P>A marine bacterium, designated SCSIO 03483<SUP>T</SUP>, was isolated from a marine sediment sample collected from the Nansha Islands in the South China Sea. The strain produced roundish colonies with diffusible yellow-coloured pigment on nutrient agar medium or marine agar 2216. Optimal growth occurred in the presence of 0–4 % (w/v) NaCl, at pH 7.0 and a temperature range of 28–37 °C. 16S rRNA gene sequence analysis indicated that the isolate belonged to the family <I>Flavobacteriaceae</I> and showed relatively high sequence similarity with <I>Imtechella halotolerans</I> K1<SUP>T</SUP> (92.7 %). Phylogenetic analysis based on nearly complete 16S rRNA gene sequences revealed that the isolate shared a lineage with members of the genera <I>Imtechella</I>, <I>Joostella</I> and <I>Zhouia</I>. Phospholipids were phosphatidylethanolamine, two unidentified aminolipids and three unknown polar lipids. The major respiratory quinone was MK-6 and the major fatty acids were iso-C<SUB>15 : 0</SUB>, iso-C<SUB>17 : 0</SUB> 3-OH and summed feature 3 (C<SUB>16 : 1</SUB>ω6<I>c</I>/C<SUB>16 : 1</SUB>ω7<I>c</I>). The DNA G+C content of strain SCSIO 03483<SUP>T</SUP> was 38.4 mol%. On the basis of phenotypic, chemotaxonomic and molecular data, strain SCSIO 03483<SUP>T</SUP> represents a novel species in a new genus in the family <I>Flavobacteriaceae</I>, for which the name <I>Sinomicrobium oceani</I> gen. nov., sp. nov. is proposed. The type strain of <I>Sinobacterium oceani</I> is SCSIO 03483<SUP>T</SUP> ( = KCTC 23994<SUP>T</SUP> = CGMCC 1.12145<SUP>T</SUP>).</P>

Jin, Long,Lee, Hyung-Gwan,Kim, Hee-Sik,Ahn, Chi-Yong,Oh, Hee-Mock International Union of Microbiological Societies 2013 International journal of systematic and evolutiona Vol.63 No.7
<P>A Gram-stain-negative, aerobic, non-spore-forming, curved, rod-shaped bacterium, H-E3-2<SUP>T</SUP>, was isolated from a water sample taken from Daechung Reservoir, Republic of Korea, during the late-blooming period of cyanobacteria. Strain H-E3-2<SUP>T</SUP> was motile with a single polar flagellum or non-motile (stalked cell). Comparative 16S rRNA gene sequence studies showed the isolate had a clear affiliation with the class <I>Alphaproteobacteria</I> and was most closely related to <I>Caulobacter fusiformis</I> ATCC 15257<SUP>T</SUP> and <I>Caulobacter mirabilis</I> LMG 24261<SUP>T</SUP>, showing 97.6 and 97.3 % 16S rRNA gene sequence similarity, respectively, and 95.3–96.3 % similarity to all other species of the genus <I>Caulobacter</I>. The predominant ubiquinone was Q-10. The major fatty acids were summed feature 8 (C<SUB>18 : 1</SUB>ω6<I>c</I> and/or C<SUB>18 : 1</SUB>ω7<I>c</I>) and C<SUB>16 : 0</SUB>. The G+C content of the genomic DNA of strain H-E3-2<SUP>T</SUP> was 64.7 mol%. DNA–DNA hybridization values of strain H-E3-2<SUP>T</SUP> with <I>C. fusiformis</I> ATCC 15257<SUP>T</SUP> and <I>C. mirabilis</I> LMG 24261<SUP>T</SUP> were 21.2 and 19.7 %, respectively. Thus, based on the results of polyphasic analysis, it is proposed that strain H-E3-2<SUP>T</SUP> represents a novel species of the genus <I>Caulobacter</I>, for which the name <I>Caulobacter daechungensis</I> sp. nov. is proposed. The type strain is H-E3-2<SUP>T</SUP> ( = KCTC 32211<SUP>T</SUP> = JCM 18689<SUP>T</SUP>).</P>
