Algae can synthesize a variety of natural products, including unsaturated fatty acids, phycobiliproteins, carotenoids, and polysaccharides, to mention a few. Among these products are algal polysaccharides, which have complicated chemical structures and excellent bioactivities (for example moisturizing, anti-radiation, immune enhancement, and anti-virus). The potential of polysaccharides as antiviral and immune-boosting strategies has been debated since the start of the COVID-19 pandemic. Currently, most algal polysaccharide research is focused on marine macroalgae, like red algae (carrageenan) and brown algae (fucoidan). In comparison with macroalgae, marine microalgae have shorter reproduction cycles, higher density cultures, and higher species richness. Thus far, between 30,000 and 40,000 different strains of microalgae have been isolated and classified. However, little research has been done on marine microalgal polysaccharides, which warrants further investigation.

Characterization of high polysaccharide producing species, the structure and composition of polysaccharides, the polysaccharide synthetic pathways and the related genes involved, optimization of the cultivation conditions, and polysaccharide extraction and purification strategies are all critical aspects to be addressed in order to boost higher production and polysaccharide yields. The present Research Topic intends to encourage more research into microalgal polysaccharides in order to develop biotechnological ways to boost yields and steer synthesis toward biomolecules with desired functionalities. It is planned to provide information on how to produce microalgal polysaccharides on a large scale.

The Research Topic welcomes research on the following areas, but are not limited to:

- Potential microalgae species for polysaccharide production
- Chemical structure of polysaccharides
- High-yield polysaccharide strategies
- Biosynthetic pathways of polysaccharides
- Low-cost extraction technologies of polysaccharides
- Polysaccharide activity evaluation and product development

We welcome the following article types: Brief Research Report, Correction, Data Report, Editorial, General Commentary, Hypothesis and Theory, Methods, Mini Review, Opinion, Original Research, Perspective, Policy and Practice Reviews, Policy Brief, Review, Systematic Review and Technology and Code.

Keywords: microalgae, polysaccharides, chemical structures, biological activity


Important Note: All contributions to this Research Topic must be within the scope of the section and journal to which they are submitted, as defined in their mission statements. Frontiers reserves the right to guide an out-of-scope manuscript to a more suitable section or journal at any stage of peer review.
