Special Issue Information

Dear Colleagues,                

The oceans are a vast reservoir of chemical diversity, as evidenced by the countless bioactive compounds produced by the many marine organisms that inhabit them. Among these, microalgae have emerged as particularly promising sources of molecules with significant biological potential, including applications in the treatment of various diseases. Their abundance and renewability make them an attractive and sustainable resource for biotechnological exploration.

To fully exploit the potential of microalgae-derived bioactives, it is necessary to develop sustainable and environmentally friendly extraction and concentrating methods. This involves the use of green, low-toxicity solvents and alternative extraction techniques, such as supercritical CO2 extraction, which minimize environmental impact while maintaining the integrity and efficacy of the active ingredients. Additionally, the formulation of the final product derived from microalgal biomass must also follow sustainable strategies to ensure a minimal ecological footprint.

Therefore, in this Special Issue, we seek high-quality papers, including reviews and articles, focused on implementing and enhancing innovative and environmentally friendly extraction and concentrating methods, together with green strategies for the formulation of bioactive compounds from marine organisms.

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. Marine Drugs is an international peer-reviewed open access monthly journal published by MDPI.

Conventional methods for extracting bioactive compounds from microalgae rely on organic solvents that are both polluting and potentially harmful to human health. In recent years, a noticeable shift has emerged toward greener extraction alternatives that are more environmentally friendly and sustainable. This review highlights various green extraction techniques, compounds, and yields obtained from different microalgal species for a range of applications and provides a comparison between the yields of conventional and green extraction methods. Green extraction methods have shown yields that are comparable to, or even exceed, those of conventional techniques, although they are predominantly studied for the extraction of lipids and pigments. This review aims to provide an overview of the current state of green extraction applied to microalgae, and to outline future research perspectives in this emerging field. Full article
