The complex dynamics between a host organism and its accompanying microbiota have long been understood as important to host health. Recent research has focused on uncover[...]

Wetlands are vital ecosystems vulnerable to threats such as metal contamination. Microorganisms have shown to mediate metal fate and bioavailability, but the influence of[...]

Microbial safety in acidified foods often requires heat treatments, compromising sensory quality. This study investigated cold-fill-hold processing on pathogen inactivati[...]

Microbiology and metabolic engineering are emerging fields with significant potential fordeveloping petroleum-free energy alternatives and advancing environmentally susta[...]

Opportunistic fungal pathogen Candida albicans often encounters host niches where it must survive on alternative carbon sources alone. In Saccharomyces cerevisiae, transc[...]

Metabolism is a complex and robust network of biochemical pathways that serve as the foundation for all biological processes of a cell. Therefore, it is imperative that c[...]

The pathogen Helicobacter pylori has evolved distinct flagellar motility to colonize the human stomach of approximately half the world’s population. Assembly and rotation[...]

A high-resolution sequencing approach, CRISPR-SeroSeq, has revealed the frequent occurrence of multiserovar Salmonella populations in food animals and the environment; th[...]

Salmonella enterica is a leading cause of bacterial foodborne illness. Ubiquitous in nature, this pathogen is well characterized in food animals; however, the prevalence,[...]

Antimony (Sb) is an industrially significant metalloid that has been exploited by humans for the last 3,000 years. Although Sb is more toxic than its well-known group 15[...]

The RidA subfamily deaminates imine/enamines, like 2-aminoacrylate (2AA). 2AA is the product of the PLP-dependent serine/ threonine dehydratase IlvA in S. enterica. In ab[...]

Fungal infections account for approximately 2.5 million deaths globally each year and billions of dollars in healthcare costs annually in just the United States. However,[...]

Cryptococcus neoformans is a ubiquitous environmental fungus and opportunistic human fungal pathogen. Due to the range of environments this fungus can be exposed to, C. n[...]

Myxococcus xanthus serves as a prokaryotic paradigm to study multicellularity in bacteria. Nutrient limitation initiates a developmental program in which the cells exhib[...]

The gastric pathogen Helicobacter pylori is remarkable in that it is able to colonize the acidic environment of the stomach, a niche not chronically colonized by any othe[...]

Msr catalyzes the reduction of oxidized methionine residues and is an important antioxidant enzyme in many bacterial pathogens as well as in humans. An H. pylori msr muta[...]

Post-transcriptional processing of all tRNA primary transcripts constitutes an important cellular activity, thought to play a role in regulation of protein synthesis[...]

Rhizobium are a unique group of bacteria classified by their ability to initiate the formation of a novel organ, the nodule, on legume plants. The Rhizobium-legume symbi[...]

The Savannah River Sites D-area harbors an exposed reject coal pile from which acidic, metal-rich saline run-off has impacted an adjacent wetland. Culture-independent 16S[...]

The combination of geological activity and geographic isolation make Uzon Caldera, Kamchatka, Russia, an ideal location for geomicrobiological research. Two hydrothermal [...]

BenM, a LysR-type transcriptional regulator of Acinetobacter sp. strain ADP1, controls expression of benABCDE, an operon involved in benzoate degradation via the ?- ketoa[...]

The organosulfur compound dimethylsulfoniopropionate (DMSP) is a valuable commodity for both the phytoplankton that produce it and the marine bacteria that degrade it. Wh[...]

The DNA site-specific invertase Piv catalyzes the inversion of a 2.1 kb segment in Moraxella lacunata and Moraxella bovis altering the expression of type 4 pilin genes in[...]
