Globally, sorghum is one of the most important but least utilized staple crops. Sorghum grain is a rich source of nutrients and health‐beneficial phenolic compounds. The phenolic profile of sorghum is exceptionally unique and more abundant and diverse than other common cereal grains. The phenolic compounds in sorghum are mainly composed of phenolic acids, 3‐deoxyanthocyanidins, and condensed tannins.

Zearalenone (ZEN) is one of the common mycotoxins with quite high occurrence rate and is harmful to animal and human health. Lactobacillus reuteri is known as a probiotic bacterium with active immune stimulating and high inhibitory activity against pathogenic microorganisms. In this study, we expressed the lactonohydrolase from Rhinocladiella mackenziei CBS 650.93 (RmZHD) in L. reuteri via secretion and surface-display patterns, respectively.

Engineered nanoparticles (NPs) could be coated by surfactants and modify the bioavailability and toxicity of heavy metals. In this study, the single and combined effect of sodium dodecyl benzene sulfonate (SDBS) and NPs on the toxicities of Cd2+ to wheat seedlings was investigated by a root elongation, and the underlying influence mechanism was further discussed. The results showed that the presence of SDBS improved the Cd2+ adsorption capacity of TiO2 and SiO2 NPs.

Aim: To show that a strain of Aeromonas hydrophila became resistant to carbapenems by interspecies transfer of a plasmid using long-read sequencing. Material & methods: Whole genome sequencing of the four isolates was done using Illumina Hiseq, while the plasmid was reconstructed using the MinION sequencer. The resistome was identified with ResFinder.

The complexity of plant microbial communities provides a rich model for investigating biochemical and regulatory strategies involved in interbacterial competition. Within these niches, the soft rot Enterobacteriaceae (SRE) represents an emerging group of plant–pathogens causing soft rot/blackleg diseases resulting in economic losses worldwide in a variety of crops.

Escherichia coli O157:H7 is the predominant cause of diarrhea-associated hemolytic uremic syndrome (HUS) worldwide. Its cardinal virulence traits are Shiga toxins, which are encoded by stx genes, the most common of which are stx1a, stx2a, and stx2c. The toxins these genes encode differ in their in vitro and experimental phenotypes, but the human population-level impact of these differences is poorly understood.

Chicken carcass frames are used to obtain mechanically separated chicken (MSC) for use in other further processed food products. Previous foodborne disease outbreaks involving Salmonella-contaminated MSC have demonstrated the potential for the human pathogen to be transmitted to consumers via MSC.

We assessed a fresh produce decontamination system using a combined method of UV and washing (water-assisted UV [WUV]) in different scales. The system used tap water to wash fresh produce while exposing it to UV light. First, the reduction of Salmonella in tap water under UV treatment (1 to 1,740 mJ/cm2) was determined.

Vibrio parahaemolyticus is a prevalent seafoodborne enteropathogen that has become a global concern since the spread of its pandemic strain in 1996. This study investigates the responses of this pathogen to the oxidative disinfectants hydrogen peroxide, chlorine dioxide, and peracetic acid. Expression of the regulator genes oxyR and rpoS, determined by reverse transcription PCR, in V.

This experiment determined the efficacy of using a novel aqueous ozone treatment as a spray chill intervention to reduce Escherichia coli O157:H7 on surfaces of fresh beef compared with traditional water spray chill. Cutaneous trunci muscles were obtained from a local beef cattle processing plant. Muscles were divided into sixteen 25-cm2 sections, and each section was individually inoculated with E. coli O157:H7 to the final concentration of approximately 105 CFU/cm2.

Monophasic Salmonella enterica subsp. enterica serovar Typhimurium is one of the most common zoonotic pathogens. Salmonella species reside in a wide variety of hosts, including wild animals. Thus, we report here the genome sequences of 12 monophasic S. Typhimurium strains isolated from healthy wild vultures to gain better insight into their epidemiology and host-pathogen interactions.

Escherichia coli serotype O157:H7 strain ATCC 43888 is a Shiga toxin-deficient human fecal isolate. Due to its reduced toxicity and its availability from a curated culture collection, the strain has been used extensively in applied research studies. Here, we report the Illumina-corrected PacBio whole-genome sequence of E. coli O157:H7 strain ATCC 43888.
