Dear Colleagues,

Biosurfactants can be defined as the surface-active biomolecules produced by microorganisms. The coexistence of hydrophilic and hydrophobic domains in the same molecule, renders them able to (i) reach interfaces, (ii) lower interfacial tension and (iii) form micelle. Biosurfactants are produced by several variety of bacteria and few fungi and are categorized by their molecular weight. There are low molecular weight molecules as glycolipids, lipo-peptides, fatty acids, phospholipids and high molecular consisting in polymers and proteins.

With the respect to the chemical surfactants, biosurfactants display lower toxicity, higher biodegradability, better environmental compatibility. Due to their unique functional properties, biosurfactants can be used as emulsifiers, wetting agents, foaming agents, spreading agents, functional food ingredients and detergents in several industries including agrochemicals, fertilizers, foods, beverages, cosmetics, pharmaceuticals and many others.

The aim of this Special Issue is to focus on some of the most recent and interesting aspects of the research about biosurfactants and on their multifaceted applications.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
