Special Issue Information

Dear Colleagues,

Beneficial microbes are abundant and all around us, as they are adaptable to many environments. One important group of beneficial microbes are probiotics, which are defined as “live microorganisms that, when administered in adequate amounts, confer a health benefit on the host”. Probiotics and other beneficial microbes can have many beneficial effects on their hosts via modulation of the gut microbiota. They can also influence other parts of the body via various axes in humans and animals, such as the gut–microbiota–brain axis, gut–microbiota–skin axis, gut–vagina axis, etc. Other beneficial microbes include microbes, which are responsible for the fermentation of foods such as yoghurt, kefir, kombucha, kimchi, and many others. The beneficial effect of these foods is enhanced due to the microbial production of nutrients, antimicrobial and antioxidant substances, as well as bioactive peptides. Last of all, microbes play a dominant role in regulating the biogeochemical cycles on our planet. The potential topics of this Special Issue will focus on the many applications of beneficial microbes including, but not limited to: beneficial microbes and host–microbiome modulation; beneficial microbes and fermented foods; novel beneficial microbes; and beneficial microbes and ecology.

Manuscript Submission Information

Manuscripts should be submitted online at 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. Applied Microbiology is an international peer-reviewed open access quarterly 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 1000 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.

Salmon lice (Lepeophtheirus salmonis) constitute a major challenge during the production of farmed Atlantic salmon in Norway. Preventive measures are considered to have a higher impact on sustainable control than lice treatment. Therefore, the studies presented here aimed to document the preventive effects of probiotic Aliivibrio spp. on lice infestation in experimental challenges. A reduction in salmon lice attachment success (58–65%) was observed in two separate aquarium trials, where Atlantic salmon were exposed to different compositions of Aliivibrio species 91 and 155 days prior to lice challenge. In a third trial, no difference in attachment was observed in groups exposed to probiotics 58 days prior to lice challenge compared to controls. However, a relative reduction in lice counts was seen on movable stages later in the trial. High levels of probiotic bacteria had no impact on lice viability in an in vitro bioassay on the preadult life stage; thus, the mechanism behind the preventative effect remains unknown. In conclusion, probiotic Aliivibrio bacteria can likely be used as a preventive tool to reduce salmon louse infestations in the salmon industry. The mechanism is still unknown, and this novel approach to lice control warrants further investigation to understand its optimal use and potential. Full article
