Summary: This study focused on the preparation and characterization of pectin and alginate films filled with halloysite loaded with salicylic acid. Different morphologies of halloysite were used for adsorption of the antimicrobial agent, showing comparable adsorption properties. The release profiles varied depending on the type of biopolymer and release medium, with alginate films demonstrating better controlled and prolonged release in ethanol mimicking food with lipophilic properties. Moreover, alginate films showed greater antimicrobial activity against food spoilage bacteria compared to pectin films.

Summary: The call to cater for the hungry is a worldwide problem in the 21st century. Food security is the utmost prime factor for the increasing demand for food. Awareness of human health when using chemical preservatives in food has increased, resulting in the use of alternative strategies for preserving food and enhancing its shelf-life. Bacteriocins, particularly those produced by lactic acid bacteria (LAB), have gained importance for their antibacterial properties and their association with food fermentation. Circular bacteriocins, with their stable circular structure, have been less studied but offer potential applications in the food industry for extending shelf-life.

Summary: Most studies on climate change and food focus on security and safety consequences, but this study highlights the overlooked impact on the microbiological stability of food. The presence of heat-resistant bacteria in processed foods can cause spoilage, and global warming can eliminate the current limiting conditions, potentially leading to a collapse in the shelf-stable food chain.

Summary: Validated methods are required to detect spoilage microbes in low numbers in foods before defect onset. Microbial composition assessments with 16S rRNA marker gene sequencing are robust for detecting very-low-abundance bacterial taxa responsible for Cheddar cheese spoilage. The application of Koch's postulates showed that individual bacterial isolates or uncultured bacterial consortia were sufficient to cause defects, even in low numbers.

Summary: This study reveals the presence of biofilms in water hoses in the food processing environment, which are mainly dominated by Proteobacteria, represented mainly by Comamonadaceae and Pseudoxanthomonas. The microbial community of biofilms is less diverse than the water microbial community, and those from different sample sites are distinct from each other.

Summary: This study aimed to identify AHL-producing bacteria in the gut of Galleria mellonella larvae and evaluate the influence of this quorum sensing signal on the regulation of adhesion and motility phenotypes in the intestinal pathogen Salmonella. It was found that R. inusitata bacteria produce a six-carbon AHL, which increases the adhesion and swarming motility of Salmonella enterica.

Summary: The study found that the intake of cooked common bean flour can improve the function of gut microbiota and alleviate the negative effects of a high-fat diet on gut health. The intake of common bean flour increased cecum weight and the moisture and lipids in excreted feces. In addition, the composition and function of cecal microbiota were also modulated by the intake of common bean flour.

Summary: In-feed antibiotics in piglets contribute to the selection of multidrug-resistant enterobacteria. Although both antibiotic-fed and control group piglets shared similar gut microbiota, a significant increase in resistance to certain antibiotics was observed in the antibiotic-fed group. The high frequency of antibiotic resistance among bacteria isolated from the control group suggests that environmental sources may serve as potential reservoirs of multidrug-resistant enterobacteria in pig production systems.

Summary: In this study, three acetic acid tolerant strains (ATS) of P. laurentii UFV-1 were selected using Adaptive Laboratory Evolution (ALE). Phenotypic analysis and whole-genome sequencing revealed that ATS I strain showed the most promising evolved characteristics, displaying oleaginous phenotype in all conditions. The study also discovered changes in cell envelope and cell size of ATS I strain under acetic acid stress conditions. These findings provided insights into the acetic acid tolerance mechanism and stress response of P. laurentii.

Summary: This study evaluated the efficacy of pH and temperature on the thermal resistance of Alicyclobacillus acidoterrestris endospores in different fruit juices. The results showed that the fruit juice matrix influenced the resistance of the endospores, with the highest heat resistance found in passion fruit juice and the greatest thermal destruction observed in papaya juice. Regardless of the fruit juice, endospores were more effectively destroyed at 95 degrees C. The pH had a more pronounced effect on reducing the heat resistance in papaya juice. The interaction of pH and temperature had the greatest impact on the reduction of endospores' thermal resistance.
