Special Issue Information

Dear Colleagues,

With rapid changes in the global food system—driven by climate change, globalization, novel food products, and evolving consumer preferences—the process of ensuring microbial safety and food quality has become more complex and critical than ever. This Special Issue seeks original research articles, reviews, and case studies that address recent advances, novel technologies, and interdisciplinary approaches in the field. We welcome contributions on topics including, but not limited to, the following:

  • Rapid detection technologies (e.g., biosensors, CRISPR-based tools, NGS);
  • Omics-based insights into microbial ecology and foodborne pathogens;
  • Natural and sustainable antimicrobial agents;
  • Microbiome impacts on food quality and fermentation;
  • Antimicrobial resistance (AMR) and One Health strategies;
  • Microbial safety in emerging food sectors (e.g., plant-based, insect-based, RTE foods).

Submissions should provide novel insights or practical applications that contribute to improving food safety, protecting public health, and supporting sustainable food systems. We invite researchers, food microbiologists, technologists, and industry professionals to contribute to this timely issue.

Dr. Kai Zhong
Guest Editor

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Foods is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Pediococcus pentosaceus, an important lactic acid bacterium in the brewing of Chinese Baijiu (liquor), usually encounters environmental stresses including ethanol and lactic acid, which severely impact cellular growth and metabolism. In this study, a combined physiological and omics analysis was employed to elucidate the response mechanisms of P. pentosaceus under ethanol and lactic acid stress conditions. The results showed that the biomass of cells decreased by about 40% under single-stress conditions and 70% under co-stress conditions. Analysis of the differentially expressed genes revealed that the cells adjusted various cellular processes to cope with environmental stresses, including modifications in cell wall synthesis, membrane function, and energy production pathways. Meanwhile, the increased expression of genes involved in DNA repair system and protein biosynthesis ensured the normal physiological function of cells. Notably, under ethanol stress, P. pentosaceus upregulated genes involved in unsaturated fatty acid biosynthesis, enhancing membrane stability and integrity. Conversely, under lactic acid stress, cells downregulated F-type ATPase, reducing H+ influx to maintain intracellular pH homeostasis. The metabolomic analysis revealed DNA damage under co-stress conditions and further validated the transcriptomic results. Our findings elucidate the molecular and physiological strategies of P. pentosaceus under acid and ethanol stress, providing a foundation for optimizing fermentation processes and enhancing microbial resilience in industrial settings.
