Special Issue Information

Dear Colleagues,

We encourage you to submit a manuscript to the Journal of Marine Science and Engineering for a Special Issue on “Marine Microbes and Their Application in Biotechnology”. Searching for novel biomolecules is of particular interest in the industry. Marine microbes possess unique metabolic pathways to adapt to life in this environment and, as a result, they are able to produce specialized compounds that differ from those produced by their terrestrial counterparts. This is due to the extreme and fluctuating salinities, pressures, and temperatures that characterize the marine environment. As a result, marine microorganisms have emerged as a significant source of novel active molecules. Recent advances in genomic approaches and synthetic microbiology have led to an increase in the number of discovered biotechnologically relevant microbial activities, and new molecules with unique features have been isolated from marine bacteria, actinomycetes, fungi, and microalgae. For this Special Issue, we are looking for experimental studies, reviews, and distributional surveys related to any aspect of microbial diversity, including ecology, molecular biology, physiology, and biotechnology, as well as eukaryotes and prokaryotes inhabiting the marine environment.

Thank you for your consideration.

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. Journal of Marine Science and Engineering 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 2600 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.

The exopolysaccharide (EPS B3-15) and biosurfactant (BS B3-15), produced by the marine Bacillus licheniformis B3-15, were recently reported to possess different antibiofilm activities, with the EPS being more active in preventing the adhesion of Pseudomonas aeruginosa and Staphylococcus aureus and the BS in destroying their preformed biofilms on different surfaces. In this study, the synergistic effects of the two exopolymers on the bacterial adhesion and biofilm disruption of P. aeruginosa and S. aureus were evaluated on polystyrene, a medical polyvinyl chloride (PVC) device, and contact lenses (CLs) in order to address their potential use in biomedical applications. To this purpose, EPS B3-15 and BS B3-15 were equally combined (1:1 w/w), and the mixture (BPS B3-15) was added at different concentrations (from 50 to 300 µg mL−1) and at different times of bacterial development. Compared to each polymer, the BPS B3-15 (300 µg mL−1) more efficiently reduced the adhesion of P. aeruginosa and S. aureus on polystyrene (65 and 58%, respectively), PVC devices (62 and 42%, respectively), and CLs (39 and 35%, respectively), also in combination with a CLs care solution (88 and 39%, respectively). Furthermore, BPS B3-15 was able to disrupt mature biofilms, acting more effectively against S. aureus (72%) than P. aeruginosa (6%). The combination of exopolymers at low concentrations exhibited synergistic effects to prevent and eradicate biofilms. Full article
