Special Issue Information

Dear Colleagues,

The fisheries and aquaculture industries represent two of the major economic sectors in the world. However, these industries generate significant amounts of processing by-products and wastes that are biologically unstable, costly to dispose of, and pose major health and environmental issues. An increasing number of investigations suggest that this biomass represents a highly valuable, renewable, and largely untapped source of industrially relevant enzymes. Therefore, the extraction and/or production of enzymes using fisheries and aquaculture processing by-products and wastes represent an attractive valorization approach.

The aim of this Special Issue is to provide a comprehensive overview of recent developments in enzymes obtained from fisheries and aquaculture processing by-products and wastes. This could include the following:

  • Methods for the extraction of enzymes from fisheries and aquaculture processing by-products and wastes, the characterization of these enzymes, and their established and potential industrial applications.
  • The utilization of fisheries and aquaculture processing by-products and wastes as substrates for enzyme production using microorganisms (including bacteria, fungi, and yeasts).

In this Special Issue, original research articles and reviews are welcome. Enzymes of interest may include, but are not limited to, proteases (pepsin, trypsin, chymotrypsin, collagenase, elastase, etc.), lipases, carbohydrases (chitinases, amylases, etc.), and transglutaminases.

I look forward to receiving your contributions.

Dr. Zied Khiari

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.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 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.

Functional Characterization of the First Bona Fide Phytoene Synthase in Red Algae from Pyropia yezoensis

Abstract
The formation of phytoene by condensing two geranylgeranyl diphosphate molecules catalyzed by phytoene synthase (PSY) is the first committed and rate-limiting step in carotenoid biosynthesis, which has been extensively investigated in bacteria, land plants and microalgae. However, this step in macroalgae remains unknown. [...] Read more.
The formation of phytoene by condensing two geranylgeranyl diphosphate molecules catalyzed by phytoene synthase (PSY) is the first committed and rate-limiting step in carotenoid biosynthesis, which has been extensively investigated in bacteria, land plants and microalgae. However, this step in macroalgae remains unknown. In the present study, a gene encoding putative phytoene synthase was cloned from the economic red alga Pyropia yezoensis—a species that has long been used in food and pharmaceuticals. The conservative motifs/domains and the tertiary structure predicted using bioinformatic tools suggested that the cloned PyPSY should encode a phytoene synthase; this was empirically confirmed by pigment complementation in E. coli. This phytoene synthase was encoded by a single copy gene, whose expression was presumably regulated by many factors. The phylogenetic relationship of PSYs from different organisms suggested that red algae are probably the progeny of primary endosymbiosis and plastid donors of secondary endosymbiosis. Full article
