Quantification of Native Lignin Structural Features with Gel-Phase 2D-HSQC0 Reveals Lignin Structural Changes During Extraction

Our ability to study and valorize the lignin fraction of biomass is hampered by the fundamental and still unmet challenge of precisely quantifying native lignin's structural features. Here, we developed a rapid elevated-temperature H-1-C-13 Heteronuclear S ...

The FDA-Approved Drug Nelfinavir Inhibits Lytic Cell-Free but Not Cell-Associated Nonlytic Transmission of Human Adenovirus

Gerardo Turcatti, Fabien Kuttler

Adenoviruses (AdVs) are prevalent and give rise to chronic and re-current disease. Human AdV (HAdV) species B and C, such as HAdV-C2, -C5, and-B14, cause respiratory disease and constitute a health threat for immunocom-promised individuals. HAdV-Cs are wel ...

Structure and Function of the T4 Spackle Protein Gp61.3

Petr Leiman, Alec Fraser

The bacteriophage T4 genome contains two genes that code for proteins with lysozyme activity-e and 5. Gene e encodes the well-known T4 lysozyme (commonly called T4L) that functions to break the peptidoglycan layer late in the infection cycle, which is requ ...

Sputtered Gum metal thin films showing bacterial inactivation and biocompatibility

César Pulgarin, Juan Kiwi, Sami Rtimi

Super-elastic Titanium based thin films Ti-23Nb-0.7Ta-2Zr-(O) (TNTZ-O) and Ti-24Nb-(N) (TN-N) (at.%) were deposited by direct current magnetron sputtering (DCMS) in different reactive atmospheres. The effects of oxygen doping (TNTZ-O) and/or nitrogen dopin ...

New evidence for Cu-decorated binary-oxides mediating bacterial inactivation/mineralization in aerobic media

César Pulgarin, Juan Kiwi, Michaël Bensimon, Sami Rtimi

Binary oxide semiconductors TiO2-ZrO2 and Cu-decorated TiO2-ZrO2 (TiO2-ZrO2-Cu) uniform films were sputtered on polyester (PES). These films were irradiated under low intensity solar simulated light and led to bacterial inactivation in aerobic and anaerobi ...

Optimizing the extraction of extracellular DNA of aerobic granular biofilms

Katarzyna Bialek

Formation and properties of aerobic granules for enhanced biological phosphorus removal (EBPR) from sequencing batch reactor (SBR) strongly depend on the extracellular polymeric substances (EPS) in which the microorganisms are embedded. The composition of ...

Rapid Cytolysis of Mycobacterium tuberculosis by Faropenem, an Orally Bioavailable beta-Lactam Antibiotic

John McKinney, Neeraj Dhar, François Signorino-Gelo

Recent clinical studies indicate that meropenem, a beta-lactam antibiotic, is a promising candidate for therapy of drug-resistant tuberculosis. However, meropenem is chemically unstable, requires frequent intravenous injection, and must be combined with a ...

An intracellular replication niche for Vibrio cholerae in the amoeba Acanthamoeba castellanii

Melanie Blokesch, Catherine Maclachlan, Tiziana Scrignari, Charles Ulric V Van der Henst

Vibrio cholerae is a human pathogen and the causative agent of cholera. The persistence of this bacterium in aquatic environments is a key epidemiological concern, as cholera is transmitted through contaminated water. Predatory protists, such as amoebae, a ...

Microfluidic Single-Cell Analysis with Affinity Beads

Horst Vogel, Rudolf Hovius, Michael Werner, Loïc Arvind Roger Arm

A micrometer-sized affinity bead (red) is (i) taken up into a cell by phagocytosis, (ii) photochemically released from phagosomes, (iii) optically trapped by the cell, and (iv) isolated by cell lysis for subsequent analysis of captured intracellular analyt ...

Single-cell lysis for visual analysis by electron microscopy

Henning Paul-Julius Stahlberg

The stochastic nature of biological systems makes the study of individual cells a necessity in systems biology. Yet, handling and disruption of single cells and the analysis of the relatively low concentrations of their protein components still challenges ...
