    ABSTRACT: A Gram-negative, strictly aerobic, non-motile, rod-shaped bacterium, designated THG-S6.8T, was isolated from soil in Incheon, South Korea. Based on 16S rRNA gene sequence, strain THG-S6.8T was moderately related to Massilia plicata 76T (97.3 %), Massilia dura 16T (97.2 %) and Massilia albidiflava 45T (96.9 %). Chemotaxonomic data revealed that strain THG-S6.8T possesses ubiquinone-8 as the predominant respiratory quinone, and summed feature 3 (C16:1ω7c and/or C16:1ω6c) and C16:0 as the major fatty acids. The major polar lipids were found to be phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. The DNA–DNA relatedness between strain THG-S6.8T and Massilia plicata KCTC 12344T and Massilia dura KACC 12342T was 38.7 and 40.5 %, respectively. The DNA G+C content was 66.8 %. These data, together with phenotypic characterization, suggest the isolate represents a novel species, for which the name Massilia humi sp. nov. is proposed, with THG-S6.8T as the type strain (=KCTC 42737T = CCTCC AB 2015296T).

    ABSTRACT: A Gram-staining-positive, solvent-tolerating (acetophenone, benzene, toluene, xylene and hexane), aerobic, non-motile, terminal endospore-forming, rod-shaped bacterium was isolated from a bottle of xylene. The strain, designated JC22(T), was found to be oxidase and catalase positive. The strain was able to tolerate solvents with different log p values like acetophenone (log P = 1.5), benzene (log P = 2.0), toluene (log P = 2.5), xylene (log P = 3.2) and hexane (log P = 3.4), though it could not use them as sole carbon sources. Based on the 16S rRNA gene sequence analysis, strain JC22(T) was identified as belonging to the genus Lysinibacillus and was most closely related to Lysinibacillus sinduriensis BLB-1(T) (98.1 %), Lysinibacillus halotolerans LAM612(T) (97.8 %), Lysinibacillus chungkukjangi 2RL3-2(T) (97.6 %) and Lysinibacillus xylanilyticus XDB9(T) (97.1 %). The DNA-DNA relatedness of strain JC22(T) with the type strains of closest species was <30 %. Strain JC22(T) grew chemoorganoheterotrophically with an optimal pH of 7-8 (range 6-10) at 35-37 °C (range 25-40 °C). The DNA G+C content was 41.2 mol%. The major cellular fatty acids were iso-C15:0, anteiso-C15:0 and iso-C16:0. Cell wall peptidoglycan type was determined to be A4α (L-Lys-D-Asp). Predominant quinone system was MK-7 with moderate amounts of MK-6, MK-6(H2) and MK-7(H2). Polar lipids of strain JC22(T) contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and an unidentified phospholipid. On the basis of morphological, physiological, genetic, phylogenetic and chemotaxonomical analyses, we conclude that strain JC22(T) be assigned the status of novel species of the genus Lysinibacillus for which the name Lysinibacillus xyleni sp. nov. is proposed. Type strain of the species is JC22(T) (= CCUG 57912(T) = KCTC 13604(T) = NBRC 105753(T) = DSM 23555(T)).

    ABSTRACT: A strictly aerobic, Gram-stain-negative, rod-shaped and non-motile bacterium, designated strain 6Alg 255(T), was isolated from the green alga Ulva fenestrata. Phylogenetic analysis based on 16S rRNA gene sequencing revealed that the novel strain affiliated to the family Rhodobacteraceae of the class Alphaproteobacteria being most closely related to Amylibacter marinus LMG 28364(T) with 16S rRNA gene sequence similarity of 97.2 %. Strain 6Alg 255(T) grew with 0.5-6.0 % NaCl and at 4-33 °C, hydrolysed aesculin, casein, gelatin and urea. The DNA G + C content was 50.4 mol%. The prevalent fatty acids were C18:1 ω7c and C16:0. The polar lipid profile was characterized by the presence of phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine and unidentified aminolipid. The major respiratory quinone was Q-10. The significant molecular distinctiveness between the novel isolate and its nearest neighbour was strongly supported by the differences in physiological and biochemical tests. Therefore, strain 6Alg 255(T) represents a novel species of the genus Amylibacter, for which the name Amylibacter ulvae sp. nov. is proposed. The type strain is 6Alg 255(T) (=KCTC 32465(T) = KMM 6515(T)).

    ABSTRACT: Phosphopantetheinyl transferases (PPTases) catalyze the posttranslational modification of acyl carrier proteins (ACPs) in fatty acid synthases (FASs), ACPs in polyketide synthases, and peptidyl carrier proteins (PCPs) in nonribosomal peptide synthetases (NRPSs) in all organisms. Some bacterial PPTases have broad substrate specificities for ACPs/PCPs and/or coenzyme A (CoA)/CoA analogs, facilitating their application in metabolite production in hosts and/or labeling of ACPs/PCPs, respectively. Here, a group II PPTase SchPPT from Streptomyces chattanoogensis L10 was characterized to accept a heterologous ACP and acetyl-CoA. Thus, SchPPT is a promiscuous PPTase and may be used on polyketide production in heterologous bacterial host and labeling of ACPs.

    ABSTRACT: Serine (Ser)/threonine (Thr) or tyrosine (Tyr) protein kinases in eukaryotes contain RDxKxxN or RDx(A/R)A(A/R)N sequences, respectively, in the catalytic loop. Myxococcus xanthus DspB is a dual-specificity kinase that contains an atypical sequence, RDVAQKN, in the catalytic loop. The DspB mutant (A165K), which contains the canonical RDxKxxN motif, had an approximate 1.3-fold increase in kinase activity toward myelin basic protein (MBP). Arginine-aspartate (RD) kinases carry a conserved Arg immediately preceding the catalytic Asp that is required for autophosphorylation of the activation loop. DspB belongs to the RD kinase family and contains one Ser residue (Ser-190) and one Thr residue (Thr-194) in the activation loop. Mutation of Ser-190 or Thr-194 to Ala did not significantly affect the kinase activity toward MBP. We previously reported that four M. xanthus eukaryotic-like kinases (EPKs) are autophosphorylated on Tyr residues. These EPKs contain six Tyr residues at homologous positions, and five of those Tyr residues, Y25, Y102, Y145, Y173, and Y205, are conserved in DspB. DspB is mainly autophosphorylated on Y145, and a Y145F mutant has reduced kinase activity, suggesting that autophosphorylation of the Tyr residue of DspB may be required for high-level kinase activity.

    ABSTRACT: The gammaproteobacterium Thiomicrospira crunogena XCL-2 is an aerobic sulfur-oxidizing hydrothermal vent chemolithoautotroph that has a CO2 concentrating mechanism (CCM), which generates intracellular dissolved inorganic carbon (DIC) concentrations much higher than extracellular, thereby providing substrate for carbon fixation at sufficient rate. This CCM presumably requires at least one active DIC transporter to generate the elevated intracellular concentrations of DIC measured in this organism. In this study, the half-saturation constant (K CO2) for purified carboxysomal RubisCO was measured (276 ± 18 µM) which was much greater than the K CO2 of whole cells (1.03 µM), highlighting the degree to which the CCM facilitates CO2 fixation under low CO2 conditions. To clarify the bioenergetics powering active DIC uptake, cells were incubated in the presence of inhibitors targeting ATP synthesis (DCCD) or proton potential (CCCP). Incubations with each of these inhibitors resulted in diminished intracellular ATP, DIC, and fixed carbon, despite an absence of an inhibitory effect on proton potential in the DCCD-incubated cells. Electron transport complexes NADH dehydrogenase and the bc 1 complex were found to be insensitive to DCCD, suggesting that ATP synthase was the primary target of DCCD. Given the correlation of DIC uptake to the intracellular ATP concentration, the ABC transporter genes were targeted by qRT-PCR, but were not upregulated under low-DIC conditions. As the T. crunogena genome does not include orthologs of any genes encoding known DIC uptake systems, these data suggest that a novel, yet to be identified, ATP- and proton potential-dependent DIC transporter is active in this bacterium. This transporter serves to facilitate growth by T. crunogena and other Thiomicrospiras in the many habitats where they are found.

    ABSTRACT: Nostoc punctiforme is a filamentous cyanobacterium which forms nitrogen-fixing symbioses with several different plants and fungi. Establishment of these symbioses requires the formation of motile hormogonium filaments. Once infected, the plant partner is thought to supply a hormogonium-repressing factor (HRF) to maintain the cyanobacteria in a vegetative, nitrogen-fixing state. Evidence implies that sucrose may serve as a HRF. Here, we tested the effects of sucralose, a non-metabolizable sucrose analog, on hormogonium differentiation. Sucralose inhibited hormogonium differentiation at a concentration approximately one-tenth that of sucrose. This result implies that: (1) sucrose, not a sucrose catabolite, is perceived by the cell and (2) inhibition is not due to a more general osmolarity-dependent effect. Additionally, both sucrose and sucralose induced the accrual of a polysaccharide sheath which bound specifically to the lectin ConA, indicating the presence of α-D-mannose and/or α-D-glucose. A ConA-specific polysaccharide was also found to be expressed in N. punctiforme colonies from tissue sections of the symbiotically grown hornwort Anthoceros punctatus. These findings imply that plant-derived sucrose or sucrose analogs may have multiple effects on N. punctiforme, including both repression of hormogonia and the induction of a polysaccharide sheath that may be essential to establish and maintain the symbiotic state.

    ABSTRACT: An exopolysaccharide (EPS)-producing heavy metal-resistant Gram-negative bacterium was isolated from ore-contaminated soil. The selected strain was identified by 16S rDNA sequencing and designated as Halomonas sp. MG. Phylogenetic analysis of the gene sequence showed its close similarity with Halomonas sp. Field emission scanning electron microscopy analysis revealed that the EPS had a porous structure with small pores. X-ray diffractograms showed the non-crystalline nature of the EPS. Further, FTIR spectroscopic analysis revealed the presence of carboxyl, hydroxyl and amide groups corresponding to a typical EPS.

    ABSTRACT: Autoinducer-2 (AI-2) serves as a quorum-sensing signaling molecule that mediates both intraspecies and interspecies communication among bacteria, and plays critical roles in regulating various bacterial behaviors. In the present study, we investigated the functions of AI-2 signaling in the extremophilic bacterium Deinococcus radiodurans R1 by construction of the LuxS gene disruption mutant, survival phenotype assay and gene transcription assay. The gene mutant (DRΔLuxS), which was unable to produce AI-2, was significantly more sensitive to both gamma radiation and H2O2 compared with the wild-type strain. Addition of the wild-type-derived spent medium into the cell culture of DRΔLuxS fully restored the radioresistance of D. radiodurans. A higher level of reactive oxygen species accumulated in the mutant compared with the wild type under normal or oxidative stress. Quantitative real-time PCR assays showed that transcriptional levels of stress-related proteins, including catalase, extracellular nuclease, Dps-1 and ABC transporters, were decreased in DRΔLuxS, indicating that AI-2 is involved in regulation of stress-related genes of D. radiodurans. Hence, AI-2 signaling may contribute to the extreme resistance of D. radiodurans to radiation and oxidative stresses.

    ABSTRACT: We continuously monitored bioluminescence from a wild-type reporter strain of Escherichia coli (lacp::luc+/WT), which carries the promoter of the lac operon (lacp) fused with the firefly luciferase gene (luc+). This strain showed a bioluminescence burst when shifted into the stationary growth phase. Bioluminescence profiles of other wild-type reporter strains (rpsPp::luc+ and argAp::luc+) and gene-deletion reporter strains (lacp::luc+/crp- and lacp::luc+/lacI-) indicate that transcriptional regulation is not responsible for generation of the burst. Consistently, changes in the luciferase protein levels did not recapitulate the profile of the burst. On the other hand, dissolved oxygen levels increased over the period across the burst, suggesting that the burst is, at least partially, caused by an increase in intracellular oxygen levels. We discuss limits of the firefly luciferase when used as a reporter for gene expression and its potential utility for monitoring metabolic changes in cells.

    ABSTRACT: The hupL of Anabaena sp. PCC 7120 encodes the large subunit of uptake hydrogenase found in all diazotrophic cyanobacteria and boosts up the nitrogen-fixing potential by catalyzing the removal of the molecular hydrogen produced as a by-product of dinitrogen fixation. Bioinformatics analysis revealed that HupL from Anabaena sp. PCC7120 is a 60.2 kDa, thermostable, glycine-rich protein having highest structural similarity with NiFeSe hydrogenase of Desulfomicrobium baculatumis. Toxicity of selected abiotic stresses like arsenic, cadmium, copper, and salt with HupL was further reconciled by wet-lab approaches like qRT-PCR, hydrogenase and nitrogenase activity assay as hydrogenases unintendedly affect the nitrogenase activity in Anabaena. Down-regulated transcript along with highly inhibited hydrogenase and nitrogenase activities under cadmium stress revealed that cadmium is a potent inhibitor of hydrogenases in Anabaena which indirectly affects its nitrogen-fixing capabilities.

    ABSTRACT: One-carbon compounds such as methanol, dimethylsulfide (DMS) and dimethylsulfoxide (DMSO) are significant intermediates in biogeochemical cycles. They are suggested to affect atmospheric chemistry and global climate. Methylotrophic microorganisms are considered as a significant sink for these compounds; therefore, we analyzed the diversity of terrestrial bacteria that utilize methanol, DMS and DMSO as carbon and energy source using culture-dependent and culture-independent methods. The effect of habitat type on the methylotrophic community structure was also investigated in rhizosphere and bulk soil. While thirteen strains affiliated to the genera Hyphomicrobium, Methylobacterium, Pseudomonas, Hydrogenophaga, Rhodococcus, Flavobacterium and Variovorax were isolated, denaturing gradient gel electrophoresis revealed the dominance of Thiobacillus, Rhodococcus, Flavobacterium and Bacteroidetes species. Furthermore, methylotrophic communities that degrade methanol or DMS are not shaped by terrestrial habitat type. Rhizosphere and soil samples showed dominance of Methylophilus spp. and Methylovorus spp. for methanol enrichments; Cytophaga spp., Pseudomonas tremae and Thiobacillus thioparus for DMS enrichments.

    ABSTRACT: Streptococcus suis (S. suis) is a swine pathogen and also a zoonotic agent. In this study, the effects of subinhibitory concentrations (sub-MICs) of emodin on biofilm formation by S. suis ATCC700794 were evaluated. As quantified by crystal violet staining, biofilm formation by S. suis ATCC700794 was dose-dependently decreased after growth with 1/2 MIC, 1/4 MIC, or 1/8 MIC of emodin. By scanning electron microscopy, the structural architecture of the S. suis ATCC700794 biofilms was examined following growth in culture medium supplemented with 1/2 MIC, 1/4 MIC, 1/8 MIC, or 1/16 MIC of emodin. Scanning electron microscopy analysis revealed the potential effect of emodin on biofilm formation by S. suis ATCC700794. The expression of luxS gene and virulence genes in S. suis ATCC700794 was investigated by quantitative RT-PCR. It was found that sub-MICs of emodin significantly decreased the expression of gapdh, sly, fbps, ef, and luxS. However, it was found that sub-MICs of emodin significantly increased the expression of cps2J, mrp, and gdh. These findings showed that sub-MICs of emodin could cause the difference in the expression level of the virulence genes.

    ABSTRACT: A novel bacterial strain THG-MM13(T) was isolated from rhizospheric soil sample and was characterized by using a polyphasic approach. Cells were Gram-reaction-negative, non-motile and rod-shaped. The strain was aerobic, catalase and oxidase positive, and optimum growth temperature and pH were 28 °C and 7.0, respectively. On the basis of 16S rRNA gene sequence analysis, strain THG-MM13(T) (KM598260) belongs to the genus Pseudoxanthomonas and is most closely related to Pseudoxanthomonas wuyuanensis KCTC 23877(T) (97.4 %) (JN247803), followed by Pseudoxanthomonas koreensis KCTC 12208(T) (96.7 %) (AY550263) and Pseudoxanthomonas yeongjuensis KACC 11580(T) (96.7 %) (DQ438977). The DNA G + C content was 63.7 mol%, and the predominant respiratory quinone was ubiquinone-8. The major polar lipids were diphosphatidylglycerol and phosphatidylethanolamine. The major fatty acids were iso-C15:0 (31.3 %) and iso-C16:0 (19.3 %). The DNA-DNA relatedness value between strain THG-MM13(T) and P. wuyuanensis KCTC 23877(T) was below 50 %. The DNA-DNA hybridization result and results of the genotypic analysis in combination with chemotaxonomic and physiological data demonstrated that strain THG-MM13(T) represented a novel species within the genus Pseudoxanthomonas, for which the name Pseudoxanthomonas humi is proposed. The type strain is THG-MM13(T) (=KACC 18280(T) = CCTCC AB 2015122(T)).
