Carbon-dependent chromate toxicity mechanism in an environmental Arthrobacter isolate
(2018-08)Arthrobacter spp. are widespread in soil systems and well-known for their Cr(VI) reduction capabilities making them attractive candidates for in situ bioremediation efforts. Cellulose drives carbon flow in soil systems; ... -
Polynomial accelerated solutions to a LARGE Gaussian model for imaging biofilms: in theory and finite precision
(2018-06)Three-dimensional confocal scanning laser microscope images offer dramatic visualizations of living biofilms before and after interventions. Here, we use confocal microscopy to study the effect of a treatment over time ... -
Endophytic fungal production rates of volatile organic compounds are highest under microaerophilic conditions
(2017-11)Volatile organic compound (VOC) production from an endophytic fungus was quantified at four oxygen concentrations (0, 1, 13 and 21 %) throughout culture growth phases. The filamentous fungus, a Nodulisporium sp. (designated ... -
Biological treatment of selenium-laden wastewater containing nitrate and sulfate in an upflow anaerobic sludge bed reactor at pH 5.0
(2018-11)This study investigated the removal of selenate (SeO42−), sulfate (SO42−) and nitrate (NO3−) at different influent pH values ranging from 7.0 to 5.0 and 20 °C in an upflow anaerobic sludge blanket (UASB) reactor using ... -
Enhancing wellbore cement integrity with microbially induced calcite precipitation (MICP): A field scale demonstration
(2018-12)The presence of delaminations, apertures, fractures, voids and other unrestricted flow channels in the wellbore environment substantially reduces wellbore integrity. Compromised cement may cause a loss of zonal isolation ... -
Biogenic coal-to-methane conversion efficiency decreases after repeated organic amendment stimulation
(2018-01)Addition of organic amendments to coal-containing systems can increase the rate and extent of biogenic methane production for 60−80 days before production slows or stops. Understanding the effect of repeated amendment ... -
Reproducibility of antimicrobial test methods
(2018-08)We review reproducibility results for methods that test antimicrobial efficacy against biofilms, spores and bacteria dried onto a surface. Our review, that included test results for Pseudomonas aeruginosa, Salmonella ... -
Microbial Functional Gene Diversity Predicts Groundwater Contamination and Ecosystem Functioning
(2018-02)Contamination from anthropogenic activities has significantly impacted Earth\'s biosphere. However, knowledge about how environmental contamination affects the biodiversity of groundwater microbiomes and ecosystem functioning ... -
How long is enough? Identification of product dry-time as a primary driver of alcohol-based hand rub efficacy
(2018-05)Background The World Health Organization has called for the development of improved methodologies to evaluate alcohol-based handrub (ABHR) efficacy, including evaluation at “short application times and volumes that reflect ... -
Dynamic processing of DOM: Insight from exometabolomics, fluorescence spectroscopy, and mass spectrometry
(2018-04)Dissolved organic matter (DOM) in freshwater environments is an important source of organic carbon, supporting bacterial respiration. Frozen environments cover vast expanses of our planet, with glaciers and ice‐sheets ... -
Assessment of Nannochloropsis gaditana growth and lipid accumulation with increased inorganic carbon delivery
(2018-04)Algal biomass refineries for sustainable transportation fuels, in particular biodiesel, will benefit from algal strain enhancements to improve biomass and lipid productivity. Specifically, the supply of inorganic carbon ... -
Low-Field Borehole NMR Applications in the Near-Surface Environment
(2018-01)The inherent heterogeneity of the near subsurface (<200 m below the ground surface) presents challenges for agricultural water management, hydrogeologic characterization, and engineering, among other fields. Borehole nuclear ... -
Competitive resource allocation to metabolic pathways contributes to overflow metabolisms and emergent properties in cross-feeding microbial consortia
(2018-04)Resource scarcity is a common stress in nature and has a major impact on microbial physiology. This review highlights microbial acclimations to resource scarcity, focusing on resource investment strategies for chemoheterotrophs ... -
Challenges and Opportunities for Tribal Waters: Addressing Disparities in Safe Public Drinking Water on the Crow Reservation in Montana, US
(2018-03)Disparities in access to safe public drinking water are increasingly being recognized as contributing to health disparities and environmental injustice for vulnerable communities in the United States. As the Co-Directors ... -
Cr(VI) reduction and physiological toxicity are impacted by resource ratio in Desulfovibrio vulgaris
(2018-03)Desulfovibrio spp. are capable of heavy metal reduction and are well-studied systems for understanding metal fate and transport in anaerobic environments. Desulfovibrio vulgaris Hildenborough was grown under environmentally ... -
Analysis of Clostridium difficile biofilms: imaging and antimicrobial treatment
(2018-01)BACKGROUND: Clostridium difficile, a spore-forming Gram-positive anaerobic bacillus, is the most common causative agent of healthcare-associated diarrhoea. Formation of biofilms may protect C. difficile against antibiotics, ... -
Live imaging analysis of human gastric epithelial spheroids reveals spontaneous rupture, rotation and fusion events
(2018-02)Three-dimensional cultures of primary epithelial cells including organoids, enteroids and epithelial spheroids have become increasingly popular for studies of gastrointestinal development, mucosal immunology and epithelial ... -
Quantifying NMR relaxation correlation and exchange in articular cartilage with time domain analysis
(2018-02)Measured nuclear magnetic resonance (NMR) transverse relaxation data in articular cartilage has been shown to be multi-exponential and correlated to the health of the tissue. The observed relaxation rates are dependent on ... -
Paired methods to measure biofilm killing and removal: a case study with Penicillin G treatment of Staphylococcus aureus biofilm
(2018-03)Biofilms are microbial aggregates that show high tolerance to antibiotic treatments in vitro and in vivo. Killing and removal are both important in biofilm control, therefore methods that measure these two mechanisms were ... -
Detection of Pseudomonas aeruginosa biomarkers from thermally injured mice in situ using imaging mass spectrometry
(2017-12)Monitoring patients with burn wounds for infection is standard practice because failure to rapidly and specifically identify a pathogen can result in poor clinical outcomes, including death. Therefore, a method that ...
