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 ... -
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 ... -
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 ... -
Community Engaged Cumulative Risk Assessment of Exposure to Inorganic Well Water Contaminants, Crow Reservation, Montana
(2018-01)An estimated 11 million people in the US have home wells with unsafe levels of hazardous metals and nitrate. The national scope of the health risk from consuming this water has not been assessed as home wells are largely ... -
Transition of biogenic coal-to-methane conversion from the laboratory to the field: a review of important parameters and studies
(2018-01)Coalbed methane (CBM) is an important unconventional natural gas resource in the U.S. and around the world. Many of the CBM containing coal formations are home to microbial communities producing the gas by converting coal ... -
Measurement of local effective diffusivity in heterogeneous biofilms
(1998-11)We have developed a novel technique to measure local effective diffusivity distribution in heterogeneous biofilms. Mobile microelectrodes (tip diameter 10 μm) and the limiting current technique were employed to measure the ...
