Special Issue Information
Dear Colleagues,
Random mutagenesis or isolation of spontaneous variants of natural actinomycetes or fungal species with different abilities to produce antibiotics than the original strains has been a strategy extensively used in industry to improve the antibiotic titer of strains of interest. A comparative analysis of the genome sequence of these over- or even down-producing variants could contribute to a better knowledge of the various processes that have an impact on antibiotic biosynthesis. This approach might lead to the identification of genes or pathways that promote or compete with or regulate the biosynthesis of already known specialized metabolites or lead to a strong enhancement of the expression of cryptic biosynthetic pathways. The outcomes of such approaches should guide the choice of rational genetic engineering strategies in clean genetic backgrounds to improve the production of already known specialized metabolites or even trigger the expression of cryptic biosynthetic pathways.
Submitted manuscripts are expected to include comparative phenotypic and genomic analysis of original strains with variants showing either enhanced or reduced production of specialized metabolites and resulting from:
- Chemical or UV random mutagenesis;
- Transposon mutagenesis;
- Deletion/mutation of genes involved in DNA repair;
- Deletion/mutation of genes leading to an alteration of transcriptional or translational fidelity;
- Growth in stressful conditions promoting extensive genome rearrangements;
- Deletion/mutation of indispensable gene leading to extensive genome rearrangements.

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.
