Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Dinitrogen oxide production by a mixed culture of nitrifying bacteria during ammonia shock loading and aeration failure [PDF]

, 2002
A number of experiments was conducted in order to establish if N2O in the exhaust gas from an aerobic consortium of nitrifiers could be used as an indicator for monitoring the nitrification process.

Recycled biowaste as a source of infection [PDF]

, 2006
Biowaste and sewage sludge can be used as a fertiliser and soil amendment in agriculture. However if not treated efficiently before use, such products can contain microbial pathogens that pose a health risk for humans and animals. This study investigated

Use of microbial fecal indicator monitoring and fecal source tracking as a park management tool in Rocky Mountain National Park

Environmental Challenges, 2022
Visitation to national parks in the United States increased by an estimated 9,304,786 visitors from 2018 to 2019. This increased visitation has resulted in negative impacts to protected natural resources.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

A cross-disciplinary toolkit to assess the risk of faecal indicator loss from grassland farm systems to surface waters. [PDF]

, 2009
Diffuse microbial pollution from agriculture is a key contributor to water quality impairment. Reducing the risk of microbial contamination of watercourses from agricultural sources requires both environmentally appropriate and socially acceptable ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

FEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

The occurrence of Aeromonas spp. in the bottled mineral water, well water and tap water from the municipal supplies

Brazilian Archives of Biology and Technology, 2008
The aim of this work was to study the occurrence of Aeromonas sp in the bottled mineral water, well water and tap water from the municipal supplies. Positive samples were found for Aeromonas spp. 12.7% from the mineral water, 8.3% from the artesian water
