Special Issue Information

Dear Colleagues,

Microorganisms are widely used in the food and feed industry for a variety of purposes, such as fermentation, preservation, and bioprocessing. The isolation and application of microorganisms in the food and feed industry has been a topic of extensive research in recent years due to the promise it holds for improving food quality and safety, increasing production efficiency, and reducing environmental impact. This Special Issue aims to presents original research articles and reviews that focus on the isolation and application of microorganisms in the food and feed industry. The topics covered in this Issue will include, but will not be limited to:

  • Discovery of novel microorganisms with breakthroughs in culture and genetic methodologies;
  • Characterization of the functional and genomic properties of microorganisms in food and feed processing;
  • Application of microbial fermentation in the production of food and feed products;
  • Bioprocessing of food and feed waste using microorganisms;
  • Microbial control of foodborne pathogens and spoilage organisms;
  • Bioremediation of food and feed processing wastewater using microorganisms

We anticipate that this Special Issue will be of interest to a wide range of researchers, students, and professionals in the fields of microbiology, food science, feed science, biotechnology, and related disciplines who are interested in exploring the potential of microorganisms to improve the food and feed industry.

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. Microorganisms is an international peer-reviewed open access monthly 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 2700 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.

Abscesses represent the most prominent emerging problem in the red meat industry, leading to great economic constraints and public health hazards. Data on etiological agents present in these purulent lesions in Algeria are very scarce. The aim of this study was to identify the bacteria responsible for these abscesses and to determine their antibiotic susceptibility profiles. A total of 123 samples of abscesses from 100 slaughtered sheep and 23 slaughtered cattle were cultured in several media. A total of 114 bacterial isolates were cultured from 103 abscesses. Bacteria were identified using MALDI–TOF, and antibiotic susceptibility was determined by the disk diffusion method on Mueller–Hinton agar. A total of 73.6% (n = 84) corresponded to Enterobacterales, of which four were multidrug-resistant (MDR). These isolates, together with Staphylococcus aureus, coagulase negative Staphylococci, and seven randomly chosen susceptible Escherichia coli isolates, were further characterized using WGS. Resistome analysis of the four MDR Enterobacterales isolates revealed the presence of OXA-48 carbapenemase in two Klebsiella pneumoniae ST985 and one E. coli ST10 isolates and a CTX-M-15 ESBL in one E. coli isolate ST1706. Two coagulase-negative Staphylococci isolates were found to carry the mecA gene. WGS showed the presence of different resistance genes and virulence genes. Our study revealed 5% of MDR Enterobacterales (including ESBLs and carbapenemases) identified from abscesses, thus urging the need for abscess monitoring in slaughterhouses. Full article
