Special Issue Information

Dear Colleagues,

Cyanobacteria are oxygen-producing bacteria, originating around 3 billion years ago. Cyanobacteria can form dense blooms in freshwater, with the most common bloom-forming genera including Microcystis, Aphanizomenon, Cylindrospermopsis, Dolichospermum, Nodularia, Planktothrix. Cyanobacterial blooms can cause major problems for water quality, producing undesirable metabolites, such as taste and odour compounds, cyanotoxins, and algal organic matter. They therefore interfere with the recreational functions of lakes and the use of reservoirs for drinking water. Cyanotoxins can cause liver, digestive, and neurological diseases when ingested by birds, mammals, and humans. Among these cyanotoxins, microcystin is the most commonly reported, and World Health Organization has set a lifetime guideline value of 1 μg/L for microcystin-LR in drinking water. Global warming and eutrophication lead to frequent outbreaks of toxic cyanobacterial blooms, and the threat they pose to water safety and human health cannot be ignored. Despite increasing research in this field, a better understanding of the diversity, physiology, ecology, and toxicology of cyanobacteria and cyanotoxins and innovative strategies and techniques to combat them is still urgently needed. This Special Issue aims to bring together scientists to share their scientific findings about cyanobacteria and cyanotoxins and their impact worldwide.

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 250 words) can be sent to the Editorial Office for assessment.

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. Microorganisms 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 2700 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.
