Summary: This study found that natamycin has antifungal effects against Penicillium strains and the two applications on Mozzarella cheese slices significantly decreased the population of P. commune while extending the shelf life of the cheese. The use of natamycin-containing hydroxyethylcellulose films may be a viable alternative to direct applications on cheese, offering a biodegradable antifungal system without compromising food safety.

Summary: The study demonstrates that the use of lactose oxidase (LO) as a surface treatment can effectively inhibit blue discoloration in fresh mozzarella cheese. In cheeses produced through direct acidification, the best results were observed with a LO concentration of 1.2 g/L, while in cheeses produced by starter fermentation, LO at the same concentration showed more consistent effects.

Summary: The study aims to assess the antimicrobial effect of cellobiose oxidase on Pseudomonas fluorescens and Escherichia coli in mozzarella cheese. The results showed that cellobiose oxidase inhibited the growth of E. coli throughout the shelf life, while P. fluorescens was only partially affected after a few days of storage.

Summary: This study aimed to determine the phenotypic and genotypic characteristics of L. monocytogenes isolates from clinical cases of Korean ruminants. The isolates exhibited diverse genetic diversity and serotype characteristics, and showed resistance to oxacillin and ceftriaxone. Further study is needed to elucidate the pathogenicity of these isolates and continuous monitoring of antimicrobial resistance is required.

Summary: This study aimed to clarify the presence of clandestine intra-hospital spread of vancomycin-resistant Enterococcus faecium (VRE-fm) and its relation to the increasing trend of healthcare-associated infections. The results showed that although there were temporary clusters of VRE-fm transmission within the hospital, there was no specific strain lingering in the hospital that led to the increasing trend of VRE-fm-HAIs. Strict contact precautions were effective in controlling intra-hospital VRE-fm spreads, but unable to curb the increasing trend of VRE-fm infections in the community.

Summary: Over the past decade, whole-genome sequencing has become the dominant method for studying genetic relatedness, surpassing traditional bacterial typing methods. These sequencing data can also be utilized in predicting antibiotic resistance, with high accuracy. These methods have the potential to be used in clinical laboratories to overcome the challenges of phenotypic susceptibility testing.

Summary: The study revealed that Campylobacter jejuni strains from Danish broilers display varying sensitivity and resistance mechanisms to phages, with different strains being susceptible to specific phages or completely resistant. Furthermore, these strains have developed diverse resistance mechanisms such as CRISPR spacers and restriction modification systems, indicating a complex evolutionary response to phage infection.

Summary: This study analyzed the clinical and molecular characteristics of MSSA ocular infections in Taiwan and compared them between CA and HA infections. CA-MSSA strains had a significantly higher rate of keratitis but a lower rate of conjunctivitis compared to HA-MSSA strains. Both CA-MSSA and HA-MSSA isolates were highly susceptible to various antibiotics.

Summary: The two-parameter Schiraldi's model fits growth curves of psychrotrophic pathogens more reliably than the Baranyi and Roberts' model. The increase of temperature has a milder effect on the growth rate than expected. Parameter beta defines the number of cell duplications and appears to be independent of temperature.

Summary: Riboflavin is an essential compound for yeast growth and a precursor of flavin coenzymes. It is photosensitive and can cause off-flavors in wine when exposed to light in the presence of methionine. The yeast strain and the initial content of riboflavin in the medium have a significant impact on the production of flavin derivatives and methionine.

Summary: Reducing production losses and increasing resource efficiency are necessary to improve the sustainability of the food supply chain. Blending and processing side streams can lead to more resource-efficient and circular food systems, especially when their value is enhanced through compositional, nutritional, or functional synergies. This perspective presents a case study on valorizing sunflower oil press cake and whey, demonstrating how combining these side streams and employing simple processing steps and novel fermentation approaches can improve circularity in the value chain and develop innovative ingredient platforms.

Summary: Commercial cheese brines can be a reservoir for salt-tolerant pathogens. This study found that the addition of hydrogen peroxide can effectively reduce the population of L. monocytogenes in cheese brines, especially at higher temperatures and salt concentrations. The presence of indigenous microorganisms may neutralize the effect of hydrogen peroxide.
