A new antibiotic kills pathogens without detectable resistance.
Nature 517(7535) , 455-9, (2015) Antibiotic resistance is spreading faster than the introduction of new compounds into clinical practice, causing a public health crisis. Most antibiotics were produced by screening soil microorganisms, but this limited resource of cultivable bacteria was over... |

Reduced sialylation impacts ventricular repolarization by modulating specific K+ channel isoforms distinctly.
J. Biol. Chem. 290(5) , 2769-83, (2015) Voltage-gated K(+) channels (Kv) are responsible for repolarizing excitable cells and can be heavily glycosylated. Cardiac Kv activity is indispensable where even minimal reductions in function can extend action potential duration, prolong QT intervals, and u... |

Reconstitution and Characterization of a Calmodulin-Stimulated Ca-Pumping ATPase Purified from Brassica oleracea L.
Plant Physiol. 100 , 1670-1681, (1992) Purification and functional reconstitution of a calmodulin-stimulated Ca(2+)-ATPase from cauliflower (Brassica oleracea L.) is described. Activity was purified about 120-fold from a microsomal fraction using calmodulin-affinity chromatography. The purified fr... |

Initiation, growth and cryopreservation of plant cell suspension cultures.
Nat. Protoc. 6(6) , 715-42, (2011) Methods described in this paper are confined to in vitro dedifferentiated plant cell suspension cultures, which are convenient for the large-scale production of fine chemicals in bioreactors and for the study of cellular and molecular processes, as they offer... |

Charon phages: safer derivatives of bacteriophage lambda for DNA cloning.
Science 196 , 161-169, (1977) The Charon lambda bacteriophages have been developed as vectors for cloning. Their construction incorporates mutations that make them simple to use and also greatly increases their safety for the biological containment of cloned recombinant DNA. Three of the ... |

Biogeography of the Sulfolobus islandicus pan-genome.
Proc. Natl. Acad. Sci. U. S. A. 106(21) , 8605-10, (2009) Variation in gene content has been hypothesized to be the primary mode of adaptive evolution in microorganisms; however, very little is known about the spatial and temporal distribution of variable genes. Through population-scale comparative genomics of 7 Sul... |

Long-term monitoring of bacteria undergoing programmed population control in a microchemostat.
Science 309 (5731) , 137-140, (2005) Using an active approach to preventing biofilm formation, we implemented a microfluidic bioreactor that enables long-term culture and monitoring of extremely small populations of bacteria with single-cell resolution. We used this device to observe the dynamic... |

Optimizing conditions for the growth of Lactobacillus casei YIT 9018 in tryptone-yeast extract-glucose medium by using response surface methodology.
Appl. Environ. Microbiol. 61 (11) , 3809-3814, (1995) This study was undertaken to find optimum conditions of tryptone, yeast extract, glucose, Tween 80, and incubation temperature for the growth of Lactobacillus casei YIT 9018 and to assess the effects of these factors by use of response surface methodology. A ... |

Survival of Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis frozen in skim milk- tryptone-glucose-glycerol medium.
J. Clin. Microbiol. 42 (1) , 412-414, (2004) In STGG (skim milk, tryptone, glucose, glycerol) medium at -80 degrees C, Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis isolates survived for at least 3 years, and the same species have survived in nasopharyngeal swabs for at lea... |

Divergent utilization patterns of grass fructan, inulin, and other nonfiber carbohydrates by ruminal microbes.
J. Dairy Sci. 99 , 245-57, (2015) Fructans are an important nonfiber carbohydrate in cool season grasses. Their fermentation by ruminal microbes is not well described, though such information is needed to understand their nutritional value to ruminants. Our objective was to compare kinetics a... |
