  1. Preparation, characterization, and phenol adsorption of activated carbons from oxytetracycline bacterial residue.
    Baohua B Zhou, Qin Q Gao, ... Neng N Zhu

    J Air Waste Manag Assoc 62(12):1394-402 (2012) PMID 23362758

    The oxytetracycline bacterial residue-activated carbon (OBR-AC) prepared from oxytetracycline bacterial residue with K2CO3 under chemical activation was studied. The effects of activation temperature, activation time, and activation ratio on the specific surface area (SSA) and methyl...
  2. Chemical composition and biological activities of essential oil from Hyptis crenata growing in the Brazilian cerrado.
    Ivana Maria Póvoa IM Violante, Walmir Silva WS Garcez, ... Fernanda Rodrigues FR Garcez

    Nat Prod Commun 7(10):1387-9 (2012) PMID 23157018

    Essential oils from species of the genus Hyptis are well-known for their significant biological properties, including antimicrobial and acaricidal activities. The essential oil from the aerial parts of H. crenata was obtained by hydrodistillation; bomeol (17.8%), 1,8-cineol (15.6%) a...
  3. Comparison of the purification performance and microbial community functional diversity in flow-directional-switching and unidirectional-flo...
    Shilong S He, Liping L Wang, ... Ningning N Yin

    J Air Waste Manag Assoc 62(10):1203-7 (2012) PMID 23155866

    Because of the characteristics of low operating cost and convenient operation, the biotrickling filter is extensively researched and used to treat low concentration waste gas contaminated by volatile organic compounds (VOCs) and other odors. In this paper, two laboratory-scale biotri...
  4. Does this adult patient with suspected bacteremia require blood cultures?
    Bryan B Coburn, Andrew M AM Morris, ... Allan S AS Detsky

    JAMA 308(5):502-11 (2012) PMID 22851117

    Clinicians order blood cultures liberally among patients in whom bacteremia is suspected, though a small proportion of blood cultures yield true-positive results. Ordering blood cultures inappropriately may be both wasteful and harmful. To review the accuracy of easil...
  5. Metabolic shift of polyphosphate-accumulating organisms with different levels of polyphosphate storage.
    B Acevedo, A Oehmen, ... R Barat

    Water Res 46(6):1889-900 (2012) PMID 22297158

    We investigated the behavior of a culture enriched with Accumulibacter at different levels of polyphosphate (poly-P) storage. The results of stoichiometric ratios Gly(degraded)/HAc(uptake), PHB(synthesized)/HAc(uptake), PHV(synthesized)/HAc(uptake) and P(release)/HAc(uptake) confirmed a metabolic sh...
  6. Distinct growth strategies of soil bacteria as revealed by large-scale colony tracking.
    Morten Ernebjerg and Roy Kishony

    Appl Environ Microbiol 78(5):1345-52 (2012) PMID 22194284

    We describe a high-throughput measurement of the growth of thousands of bacterial colonies using an array of flat-bed scanners coupled with automated image analysis. We used this system to investigate the growth properties of members of a microbial community from untreated soil. The system provides...
  7. Pressure to kill or pressure to boost: a review on the various effects and applications of hydrostatic pressure in bacterial biotechnology.
    Stéphanie S Follonier, Sven S Panke, and Manfred M Zinn

    Appl Microbiol Biotechnol 93(5):1805-15 (2012) PMID 22290643

    Much knowledge has been gained for the last 30 years about the effects of pressure on bacteria, and various pressure-based technologies have been designed. The development of modern molecular biology techniques (e.g., DNA microarrays) as well as the technological advances realized in...
  8. A specific mix of generalists: bacterial symbionts in Mediterranean Ircinia spp.
    Patrick M PM Erwin, Susanna S López-Legentil, ... Xavier X Turon

    FEMS Microbiol Ecol 79(3):619-37 (2012) PMID 22092516

    We characterized the bacterial symbiont communities of three sympatric host species in the genus Ircinia from the NW Mediterranean Sea, using electron microscopy and replicated 16S rRNA gene sequence clone libraries. All Ircinia host species harbored abundant and phylogenetically diverse symbiont co...
  9. Distinct growth strategies of soil bacteria as revealed by large-scale colony tracking.
    Morten Ernebjerg and Roy Kishony

    Appl Environ Microbiol 78(5):1345-52 (2012) PMID 22194284

    We describe a high-throughput measurement of the growth of thousands of bacterial colonies using an array of flat-bed scanners coupled with automated image analysis.

  10. Characterization of microbial communities during anode biofilm reformation in a two-chambered microbial electrolysis cell (MEC).
    Wenzong W Liu, Aijie A Wang, ... Jizhong J Zhou

    J Biotechnol 157(4):628-32 (2012) PMID 21939699

    GeoChip (II) and single strand conformation polymorphism (SSCP) were used to characterize anode microbial communities of a microbial electrolysis cell (MEC). Biofilm communities, enriched in a two-chamber MEC (R1, 0.6 V applied) having a coulombic efficiency (CE) of 35±4% and a hydr...
