Abstract Staphylococcus aureus causes severe infections and among all methicillin-resistant S. aureus (MRSA) remains a great challenge in spite of decade research of antibacterial compounds. Even though some synthetic antibiotics have been developed, they are not effective against MRSA, and hence, there is a search for natural, alternative and plant-based antibacterial compound. In this...

Abstract Arabinanases from glycoside hydrolase family GH93 are enzymes with exo-activity that hydrolyze the α-1,5 bonds between arabinose residues present on arabinan. Currently, several initiatives aiming to use byproducts rich in arabinan such as pectin and sugar beet pulp as raw material to produce various compounds of interest are being developed. However, it is necessary to use robust...

The leading causes of foodborne viral disease outbreaks are human norovirus and hepatitis A virus (HAV). Their environmental persistence enables contamination of kitchen surfaces and crops often consumed raw, such as berries. Many decontamination procedures are inefficient and unsuitable for surfaces of industrial kitchen environments and soft fruits. In this study, we investigated the efficiency...

Yeast extract (YE) is tremendously used as a flavor enhancer in foods because of its composition. However, different types of YE have different aromatic profiles. This study focuses on the thermal treatment of glutathione-enriched yeast extract (GSH-YE) at different temperatures with the addition of Maillard precursors to investigate any change in its volatile organic profile. Headspace gas...

Chloramphenicol is a broad-spectrum antibiotic that is administered to cattle, fish, poultry, and honeybees among other animals. Consumption of food from such sources leads to non-regenerative anaemia, aplastic anaemia, and bone marrow suppression in humans. It is therefore a pressing necessity to detect chloramphenicol in food items through a convenient, accurate, and rapid method. The proposed...

Bacillary dysentery caused by Shigella flexneri is a major cause of under-five mortality in developing countries, where a novel S. flexneri serotype 1c has become very common since the 1980s. However, the origin and diversification of serotype 1c remain poorly understood. To understand the evolution of serotype 1c and their antimicrobial resistance, we sequenced and analyzed the whole-genome of...

Aims Antimicrobial resistance genes (ARGs) are often associated with mobile genetic elements (MGEs), which facilitate their movement within and between bacterial populations. Detection of mobility is therefore important to understand the dynamics of MGE dissemination and their associated genes, especially in resistant clinical isolates that often have multiple ARGs associated with MGEs. Therefore...

Cadmium (Cd) is a toxic heavy metal with no known biological functions in the human body. Due to a considerably long biological half‐life and very low rate of excretion, accumulation of Cd in different body organs (eg, liver, kidney, and testes) over time is associated with perturbed functioning of these organs. Recent studies have shown the extreme sensitivity of the testes to Cd toxicity. In...

SYTO 9 is a fluorescent nucleic acid stain that is widely used in microbiology, particularly for fluorescence microscopy and flow cytometry analyzes. Fluorimetry-based analysis, i.e., analysis of fluorescence intensity from a bulk sample measurement, is more cost effective, rapid and accessible than microscopy or flow cytometry but requires application-specific calibration. Here we show the...

Lead is a metal capable of affecting physiology and metabolism in fish, including Nile tilapia (Oreochromis niloticus). However, few studies have evaluated the effects of lead on digestive enzyme activities in fry. At that stage, independent feeding begins, and there is increased demand and consumption of food, so chronic exposure to metal during this stage of development would cause null or...

Proteins and polysaccharides are widely used as ingredients in food emulsions due to their high biocompatibility, good biodegradability, and a broad range of techno‐functionalities. In particular, they are used as emulsifiers, texture modifiers, and stabilizers in many emulsion‐based foods. Moreover, the functionality of these biopolymers can be extended by forming protein–polysaccharide...

Sulfane sulfur such as glutathione persulfide (GSSH) is produced from H2S oxidation or from L‐cysteine metabolism. It accumulates inside Pseudomonas aeruginosa PAO1 during the stationary phase of growth, inactivating a repressor to increase the expression of a major multidrug efflux pump. The finding explains why the bacterium is relatively resistant to antibiotics at the stationary phase of...

BackgroundBacterial biofilms are known to have high antibiotic tolerance which directly affects clearance of bacterial infections in people with cystic fibrosis (CF). Current antibiotic susceptibility testing methods are either based on planktonic cells or do not reflect the complexity of biofilms in vivo. Consequently, inaccurate diagnostics affect treatment choice, preventing bacterial...

Honey bees are important agricultural pollinators that rely on a specific gut microbiota for the regulation of their immune system and defense against pathogens. Environmental stressors that affect the bee gut microbial community, such as antibiotics and glyphosate, can indirectly compromise bee health. Most of the experiments demonstrating these effects have been done under laboratory conditions...

The marine facultative pathogen Vibrio cholerae forms complex multicellular communities on the chitinous shells of crustacean zooplankton in its aquatic reservoir. V. cholerae-chitin interactions are critical for the growth, evolution, and waterborne transmission of cholera. This is due, in part, to chitin-induced changes in gene expression in this pathogen. Here, we sought to identify factors...
