Special Issue Information
Dear Colleagues,
A biological phenomenon known as allelopathy occurs when an organism creates one or more macromolecules that have an impact on the development, maintenance, and/or reproduction of other species.
These biomolecules, known as allelochemicals, are primarily secondary metabolites and are produced by specific plants, algae, bacteria, coral, and fungi. These substances may benefit the target organism (positive allelopathy) or harm it (negative allelopathy). Within plant and plankton communities, allelopathic interactions play a significant role in defining the number and distribution of various species. Other ecological roles played by biomolecules with allelopathic properties include nutrient chelation, chemical defense, and soil biota management in plants.
Natural herbicides could be made from these molecules, and in recent years, allelopathy has been the focus of extensive investigation.
Engineering methods used in the development and construction of photobioreactors must rely on our understanding of the behavior and microbiology of that specific strain of microalgae, including its genetic make-up and metabolic pathways. However, the employment of techniques that avoid biological contamination, predators/grazers, and parasites of diverse origins is the only way to cultivate microalgae in open environments. There are still many unknown issues concerning the physiology and behavior of microalgae, and this branch of biotechnology is still in its infancy. Furthermore, there is always a risk of culture contamination. Other species of microalgae may enter the system and compete with the primary microalgae, or fungi, protozoa, and bacteria may cause culture crash or dominance of unwanted algae species. Air, dust, leaves, and other items carried by the wind, as well as insects, can all be sources of significant contamination.
This Special Issue aims at adding knowledge to the phenomenon of allelopathy as manifested in marine microalgal culture in order to maintain the monoculture of the selected species, thus maximizing the production of its biomass and useful bio-substances.

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.
