Special Issue Information

Dear Colleagues,

Over the last several decades, cultivation of microalgae has evolved into a globally established, economically important branch of biotechnology. Microalgal biotechnology and its derived technologies are now considered among the most promising responses to global challenges. Currently most mature and commercially successful are the microalgae-based processes for the production of nutraceuticals (carotenoids and fatty acids), fine chemicals (including potential therapeutants), cosmetic ingredients, feed and food ingredients. Microalgae can be cultured by sustainable methods thus providing a wide range of health beneficial metabolites from natural sources with lesser environmental impact. Significant increase in biomass productivity is needed to reach economic viability of algal production. Algal cultivation shows a great potential for efficient recovery of nutrients and carbon from waste and side streams, thereby contributing to the circular bio-economy for improved resource management, particularly in arid environments. Economic viability of algal biotechnology can be improved by increasing productivity and by selecting species that produce high-value compounds that are beneficial for human and animal health.

This Special Issue is intended to integrate the progress in overcoming the current barriers for improving the efficiency of microalgal biotechnologies and their practical implementation. We welcome contributions deepening on the mechanistic insights into the key determinants of microalgal productivity and stress resilience, as well as on application in aquaculture. In addition to full-length research articles we would be happy to consider your minireviews summarizing the recent progress in the field after prior negotiation of the topic with the editors of the Special Issue.

This issue is planned to be associated with a session at Drylands, Deserts and Desertification 2020, The 7th International Conference, 15–19 November 2020 https://dddconf.org/. This issue is also open for submissions by scholars besides participants of this meeting.

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 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. Biology 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 1400 CHF (Swiss Francs).

Abstract: We report, for the first time, on successful application of the cross-linked chitosan-based polymers for microalgae (MA) immobilization and biocapture of nutrients. the materials were highly porous, hydrophilic solid polymers from 250- or 600-kDA chitosan synthesized by cross-linking with glutaraldehyde. The cross-linked chitosan polymers were characterized by a high MA immobilization efficiency. They and allowed prolonged cultivation of immobilized Lobosphaera sp. IPPAS 2047 cells without impairing cell growth, viability, and photosynthetic activity. The 600 kDA-chitosan polymers demonstrated higher mechanical and biological stability than those based on 250 kDa chitosan during prolonged incubation in a nutrient-rich medium. The nutrient removal capacity of the chitosan-immobilized Lobosphaera sp. IPPAS 2047 cells was significantly higher as compared to suspended cells.  The rate of nitrate consumption by the immobilized cells was 1.4−3.2 times higher during a 13-d experiment. Chitosan-immobilized Lobosphaera sp. IPPAS 2047 completely remove inorganic phosphate within 2 days, while the suspended cells consumed was six times lower amount of the nutrient under similar conditions. The results of this work showed that cross-linked сhitosan polymers are environment-friendly materials with a great potential for technologies of nutrient bioremoval with immobilized microalgae cells. The nutrient-enriched microalgae biomass immobilized on cross-linked chitosan polymers can be utilized as a bio-fertilizer.
