Special Issue Information

Dear Colleagues,

This Special Issue contains communications, full research papers, and reviews pertaining to the following topics:

(1) Purification, spectroscopic structure elucidation, and biological characterization (with requisite in vitro antibacterial MIC (uM) and mammalian cytotoxicity study (uM)) of novel antibacterial compounds derived from marine organisms.

Marine antibacterial compounds include:

- bacteriostatic or bacteriocidal agents

- quorum sensing antagonists

- antiproliferative agents, e.g., inhibitors of bacterial enzymes disrupting the tissue matrix

- inhibitors of cancer-causing or cancer-aiding effects of bacterial infection

Full spectroscopic data (original proton, carbon-13, 2D NMR spectra, and HRMS) and purity confirmation (LCMS chromatogram or elemental analysis) must be included.

(2) Study of biological marine antibacterial agents

- bacteriophages 

- predatory bacteria

(must include in vitro animal cell cytotoxicity study against cells from relevant species, e.g., poultry cell cytotoxicity for an antibacterial agent eliminating a poultry infection)

(3) Investigation of antibacterial selectivity of known or new marine antibacterial agents towards marine vs. terrestrial bacteria

(4) Mechanism of action of marine antibacterial agents, new or previously reported

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 papers will be 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. Marine Drugs 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 1800 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 microbiome of three different sites at the Peruvian Pacific coast was analyzed, revealing a lower bacterial biodiversity at Isla Foca than at Paracas and Manglares, with 89 bacterial genera identified, as compared to 195 and 173 genera, respectively. Only 47 of the bacterial genera identified were common to all three sites. In order to obtain promising strains for the putative production of novel antimicrobials, predatory bacteria were isolated from these sampling sites, using two different bait organisms. Even though the proportion of predatory bacteria was only around 0.5% in the here investigated environmental microbiomes, by this approach in total 138 bacterial strains were isolated as axenic culture. 25% of strains showed antibacterial activity, thereby nine revealed activity against clinically relevant methicillin resistant Staphylococcus aureus (MRSA) and three against enterohemorrhagic Escherichia coli (EHEC) strains. Phylogeny and physiological characteristics of the active strains were investigated. First insights into the chemical basis of the antibacterial activity indicated the biosynthetic production of the known compounds ariakemicin, kocurin, naphthyridinomycin, pumilacidins, resistomycin, and surfactin. However, most compounds remained elusive until now. Hence, the obtained results implicate that the microbiome present at the various habitats at the Peruvian coastline is a promising source for heterotrophic bacterial strains showing high potential for the biotechnological production of antibiotics.
