Special Issue Information

Dear Colleagues,

Microorganisms, such as bacteria, yeast, algae, and mold, have been utilized to enrich our daily life in food for thousands of years. The ways of conventional uses and manufacturing process are based on innumerable practical experiences. Useful materials such as energy resources, preservation agents, flavor enhancers, and functional substances can be produced according to specific fermentation process, cultivation or reaction. Owing to progress of Nematoda mode, Next Generation Sequencing and metabolomics technologies, the comprehensive analysis of the processes can be further achieved. Some procedures or substances in the processes with undervaluation can be reevaluated bases on the bioinformatics analysis. For example, the by-product of manufacturing process is believed to have valuable substances which are functional, such as anti-aging, anti-oxidation, nutritional supplementary, but underestimated. The concept of sustainable utilization is to investigate the undeveloped value or novel uses of the underestimated substances which are produced from cultivation or food processing. By reducing biowaste generation, more circular economy and regenerative agriculture can be therefore achieved. We invite the papers about microbiological technologies, affording excellent creativity to utilize biowaste, such as agricultural waste or food waste, more effectively and promoting circular economy and regenerative agriculture, to submit to this special issue.

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. Sustainability 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 2400 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.

Rice husk (RH) contains abundant silica such that RH silica (RHS) may be useful for possible industrial exploitation. Here, amorphous silica nanoparticles with multiple pore structures were acquired from RH by simple thermochemical processes. RHS antimicrobial activity and effects on zebrafish innate immunity against pathogen infections were evaluated. A toxicity assay showed that zebrafish exposed to an RHS dose lower than 200 μg/mL did not exhibit damage to zebrafish embryonic development or juvenile survival. RHS showed a wide spectrum of bacteriostatic activity against a variety of pathogens including antibiotic-resistant pathogens, implying its potential application as an antimicrobial agent in diverse industries. Fish exposed to 20 or 200 μg/mL RHS exhibited significantly increased mRNA expression of immune-related genes, including IL-1β, IL-6, IL-15, TNF-α, COX-2a, TLR-4a, lysozyme, and complement C3b. RHS-treated zebrafish exhibited a higher cumulative survival compared to that in control fish after infecting with Aeromonas hydrophila and Streptococcus iniae. The present results showed that a safe RHS dose enhanced innate immunity against infections without toxic effects in healthy fish, suggesting that RHS may be developed as an immunostimulant for improving health status in aquaculture.
