<P>Strain DCY21<SUP>T</SUP>, a Gram-negative, gliding and rod-shaped aerobic bacterium was isolated from soil of a ginseng field in the Republic of Korea and characterized using a polyphasic approach in order to determine its taxonomic position. Comparative 16S rRNA gene sequence analysis revealed that strain DCY21<SUP>T</SUP> clustered with the species of the genus <I>Lysobacter</I>. It was closely related to <I>Lysobacter gummosus</I> LMG 8763<SUP>T</SUP> (97.9 %), <I>Lysobacter capsici</I> YC5194<SUP>T</SUP> (97.6 %), <I>Lysobacter antibioticus</I> DSM 2044<SUP>T</SUP> (97.5 %), <I>Lysobacter niastensis</I> DSM 18481<SUP>T</SUP> (97.2 %) and <I>Lysobacter enzymogenes</I> DSM 2043<SUP>T</SUP> (96.9 %). The major cellular fatty acids of strain DCY21<SUP>T</SUP> were iso-C15 : 0 (34.3 %), iso-C17 : 1<I>ω</I>9<I>c</I> (19.5 %) and iso-C17 : 0 (17.2 %) and the major isoprenoid quinone was Q-8. The major polar lipids of strain DCY21<SUP>T</SUP> were diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and phosphatidyl-<I>N</I>-methylethanolamine. The G+C content of the total DNA was 65.4 mol%. The DNA-DNA relatedness values, and biochemical and physiological characteristics strongly supported the genotypic and phenotypic differentiation of strain DCY21<SUP>T</SUP> from species of the genus <I>Lysobacter</I>. Strain DCY21<SUP>T</SUP> therefore represents a novel species, for which the name <I>Lysobacter soli</I> sp. nov. is proposed. The type strain is DCY21<SUP>T</SUP> (=KCTC 22011<SUP>T</SUP> =LMG 24126<SUP>T</SUP>).</P>
Pusillimonas ginsengisoli sp. nov., isolated from soil of a ginseng field
Srinivasan, Sathiyaraj,Kim, Myung Kyum,Sathiyaraj, Gayathri,Kim, Yeon-Ju,Yang, Deok-Chun Microbiology Society 2010 International journal of systematic and evolutiona Vol.60 No.8
<P>Two novel strains of Gram-negative, non-sporulating, short rod-shaped, motile bacteria, designated DCY25<SUP>T</SUP> and DCY28, were isolated from soil of a ginseng field in South Korea and characterized in order to determine their taxonomic position. 16S rRNA gene sequence analysis showed that strains DCY25<SUP>T</SUP> and DCY28 belonged to the <I>Betaproteobacteria</I>, the highest sequence similarities being found with <I>Pusillimonas noertemannii</I> BN9<SUP>T</SUP> (96.9 %), <I>Bordetella trematum</I> DSM 11334<SUP>T</SUP> (95.9 %), <I>Achromobacter denitrificans</I> DSM 30026<SUP>T</SUP> (95.9 %), <I>Achromobacter insolitus</I> LMG 6003<SUP>T</SUP> (95.8 %) and <I>Pigmentiphaga kullae</I> K24<SUP>T</SUP> (95.5 %). Chemotaxonomic data revealed that both strains DCY25<SUP>T</SUP> and DCY28 possessed ubiquinone Q-8. Fatty acid analysis of strain DCY25<SUP>T</SUP> demonstrated the presence of 19 : 0 cyclo <I>ω</I>8<I>c</I> (22.8 %) and 16 : 0 (16.6 %). The polar lipid profiles of strains DCY25<SUP>T</SUP> and DCY28 included phosphatidylethanolamine, phosphatidylglycerol, two unknown aminolipids and diphosphatidylglycerol. The G+C contents of strains DCY25<SUP>T</SUP> and DCY28 were 57.3 and 57.2 mol%, respectively. DNA-DNA relatedness values, biochemical and physiological characteristics strongly supported the genotypic and phenotypic differentiation of strains DCY25<SUP>T</SUP> and DCY28 from <I>Pusillimonas noertemannii</I>. Therefore, strains DCY25<SUP>T</SUP> and DCY28 should be classified in a novel species, for which the name <I>Pusillimonas ginsengisoli</I> sp. nov. is proposed. The type strain is DCY25<SUP>T</SUP> (=KCTC 22046<SUP>T</SUP> =JCM 14767<SUP>T</SUP>); strain DCY28 (=KCTC 22047=JCM 14768) is a reference strain.</P>

αB-crystallin (αBC) is a member of a small heat-shock protein (sHSP) superfamily and plays a predominant role in cellular protein homeostasis network by rescuing misfolded proteins from irreversible aggregation. αBC assembles into dynamic and polydisperse high molecular weight complexes containing 12 to 48 monomers; this variable stereochemistry of αBC has been linked to quaternary subunit exchange and its chaperone activity. The chaperone activity of αBC poses great potential as therapeutic agents for various neurodegenerative diseases. In this mini-review, we briefly outline the recent advancement in structural characterization of αBCs and its potential role to inhibit protein misfolding and aggregation in various human diseases. In particular, nuclear magnetic resonance (NMR) spectroscopy and its complimentary techniques have contributed much to elucidate highly-dynamic nature of αBCs, among which notable advancements are discussed in detail. We highlight the importance of resolving the structural details of various αBC oligomers, their quaternary dynamics, and structural heterogeneity.

A frequent pack burst spoilage is occurring in gochujang (fermented hot pepper paste) products during the transportation and storage period, resulting in economic loss. Thus, the present investigation aimed to develop a heat processing-based method to prevent pack burst spoilage of gochujang products. The direct heat (75℃, 3 min) treatment significantly reduced (80%, p<0.05) the pack burst spoilage of gochujang products. The color values and moisture content of gochujang products were reduced, whereas pH and amino nitrogen content increased in the direct heat-treated gochujang products. The total aerobic bacterial count was not reduced significantly, however, a considerable reduction of yeasts and mold counts (0.59–3.0 log CFU/g, p<0.05) was found in heat-treated gochujang products. A significant reduction in the yeast count due to the direct heat treatment resulted in the control of aerogenesis in gochujang, which consequently reduced the pack burst spoilage. The present findings concluded that direct heat treatment inhibits the pack burst spoilage in gochujang products.
