Special Issue Information
Dear Colleagues,
Mixotrophy is broadly defined as the combined use of autotrophy and heterotrophy in a single microorganism, where heterotrophy means the utilization of dissolved organic substrates (i.e., chemo-heterotrophy) or/and grazing on particulate organic matter (i.e., phago-heterotrophy). According to the difference in the heterotrophic mode used, mixotrophy can be further divided into phago-mixotrophy and chemo-mixotrophy. Compared to a single nutritional mode, the use of diverse nutritional modes offers a higher survival rate for phago-mixotrophic protists encountering complicated and changeable environments. For example, some dinoflagellates can graze on bacteria and other nutrient-competitive microalgae, therefore easily dominating the aquatic environment and causing water bloom. In addition, these bacteria-eating flagellates/microalgae are considered to be an indispensable component of the microbial food loop. On the other hand, mixotrophy provides more strategies to cultivate microalgae with application value. Therefore, cultivation mode is one of the main factors affecting the cultivation and resource utilization of mixotrophic microalgae. Although mixotrophy is widely present in protists, little is known about its evolutionary origin and ecological significance. This Special Issue aims to collect original research articles or reviews focusing on revealing the important roles of mixotrophy in protists. Research areas may include (but are not limited to) the following:
- The origin and evolution of mixotrophy in protists;
- The ecological distribution and significance of mixotrophy in the aquatic environment;
- Mechanisms of nutritional transformation in mixotrophic protists;
- The cultivation of mixotrophic protists and their application.
We look forward to receiving your contributions.

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. 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.
Benefits of Publishing in a Special Issue
