Black lines represent growth under Pearce assay conditions (Temperature: 32 °C for 70 min, 32–38 °C for 30 min, 38 °C for 160 min, 32 °C for 40 min). Red (subsp. cremoris) and blue (subsp. lactis) lines represent controls grown at 30 °C for 300 min. (PPTX 96 kb

Undercooling and rapid solidification of Cu84Co16 alloys under a static magnetic field
Bulk samples of Cu84Co16 composition were undercooled and rapidly solidified using the electromagnetic levitation technique under a static magnetic field of 2 T. A droplet-shaped microstructure was frozen in due to metastable phase separation in the undercooled liquid. A singular droplet size distribution was determined for the minority Co-rich phase, which differed from a bimodal one observed in the samples levitated without the static magnetic field. Such an effect of the magnetic field was found to be similar to that of reduced gravity of parabolic flights

Phylogenomics of <i>Lactobacillus rossiae</i> DSM 15814<sup>T</sup>.
<p>A) 16S neighbor-joining (NJ) tree, resulting from the alignment of the 16S rRNA-encoding gene of <i>L. rossiae</i> DSM 15814<sup>T</sup> and that of 20 selected representatives of the <i>Lactobacillus</i> genus (<i>L. amylovorus</i> GRL 1112, <i>L. acidophilus</i> 30SC, <i>L. kefiranofaciens</i> ZW3, <i>L. crispatus</i> ST1, <i>L. helveticus</i> DPC 4571, <i>L. gasseri</i> ATCC 33323, <i>L. johnsonii</i> NCC 533, <i>L. delbrueckii</i> subsp. <i>bulgaricus</i> ATCC 11842, <i>L. sakei</i> subsp. <i>sakei</i> 23K, <i>L. rhamnosus</i> ATCC 8530, <i>L. paracasei</i> subsp. <i>paracasei</i>, <i>L. casei</i> ATCC334, <i>L. ruminis</i> ATCC 27782, <i>L. salivarius</i> UCC118, <i>L. fermentum</i> IFO 3956, <i>L. reuteri</i> DSM 20016, <i>L. plantarum</i> WCFS1, <i>L. brevis</i> ATCC 367, <i>L. buchneri</i> NRRL B-30929 and <i>L. sanfranciscensis</i> TMW 1.1304). The corresponding 16S rRNA-specifying sequence of <i>Bifidobacterium breve</i> UCC2003 was used as an outgroup. The positioning of <i>L. rossiae</i> DSM 15814<sup>T</sup> within the <i>Lactobacillus</i> genus is indicated in red.

Luminescence signal of the <i>V. harveyi</i> BB170 biosensor strain in the presence of sterile and neutralized supernatant of <i>B. breve</i> UCC2003, the insertion mutant <i>B. breve</i> UCC2003-luxS and the complemented strain <i>B. breve</i> UCC2003-luxS [pBC1.2luxS].
<p>Data obtained with <i>E. coli</i> DH5α (a strain not producing AI-2) and a medium-only control are included as reference. Data shown are means ± SEM. (*, luminescence is significantly lower than than produced with supernatant of <i>B. breve</i> UCC2003, p<0.05, compared to WT; n = 3).</p
Comparison of the <i>lux</i>S genetic loci of <i>B. breve</i> UCC2003 with corresponding <i>lux</i>S loci from other sequenced bifidobacteria.
<p>Each solid arrow indicates an open reading frame. The lengths of the arrows are proportional to the length of the predicted open reading frame. The colour coding which is indicative of putative function, is indicated within the arrow. Orthologs are marked with the same colour while the amino acid identity of each predicted protein is indicated as a percentage relative to its equivalent protein encoded by <i>B. breve</i> UCC2003.</p
Relative survival of <i>Salmonella</i>-infected <i>C. elegans</i> nematodes to which <i>B. breve</i> UCC2003 WT or mutants UCC2003-bfeU or UCC2003-bfeB were administered (24 h {blue bars} and 48 h {white bars} after <i>Salmonella</i> infection).
<p>Data shown are means ± SEM. Control: infected nematodes that have not been administered any bifidobacteria. (*  =  significantly different as compared to the control, p<0.05; n = 3).</p
