Special Issue Information

Dear Colleagues,

Interest in the recovery of natural polymers from a number of sources has steadily increased over recent years, driven by the environmental problems associated with synthetic plastics. To become truly sustainable, these biopolymers should ideally be sourced within zero-waste production schemes. The marine environment harbours a stunning diversity of polymeric materials endowed with a range of properties adequate for a number of applications. However, so far, only a handful of molecules represents viable alternatives for industrial production, as beyond the required properties from the intended application they must be available in large quantities, at relatively low cost and be sustainably sourced. Because marine organisms are for the most part destined to human consumption, the most logical approach is to integrate valorisation of by-products generated by the fishing and associated food industry into current industrial processes. With this perspective, chitosan and gelatine stand out as two prominent biomolecules that can be obtained from fish by-products.

This Special Issue aims at covering a holistic approach to gelatine and chitosan from marine food by-products, from novel isolation processes and characterization of biomolecules from new sources, to chemical modifications to suit particular applications, including also performance in specific applications of both native and chemically-modified gelatine and chitosan.

Research paper and reviews are welcome.

Manuscripts can be submitted until the deadline. All papers will be 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. Polymers is an international peer-reviewed open access semimonthly 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 2200 CHF (Swiss Francs).

Abstract
Chitosan is a natural polymer, and its biological properties depend on factors such as the degree of deacetylation and polymerization, viscosity, molecular mass, and dissociation constant. Chitosan has multiple advantages: it is biodegradable, biocompatible, safe, inexpensive, and non-toxic. Due to these characteristics, it [...] Read more.
Chitosan is a natural polymer, and its biological properties depend on factors such as the degree of deacetylation and polymerization, viscosity, molecular mass, and dissociation constant. Chitosan has multiple advantages: it is biodegradable, biocompatible, safe, inexpensive, and non-toxic. Due to these characteristics, it has a wide range of applications. In agriculture, one of the most promising properties of chitosan is as an elicitor in plant defense against pathogenic microorganisms. In this work, four kinds of chitosan (practical grade, low molecular weight, medium molecular weight, and high-density commercial food grade) were used in concentrations of 0.01 and 0.05% to evaluate its protective effect against coffee rust. The best treatment was chosen to evaluate the defense response in coffee plants. The results showed a protective effect using practical-grade and commercial food-grade chitosan. In addition, the activity of enzymes with β-1,3 glucanase and peroxidase was induced, and an increase in the amount of phenolic compounds was observed in plants treated with high-molecular-weight chitosan at 0.05%; therefore, chitosan can be considered an effective molecule for controlling coffee rust.
