Concepts and Trends for Extraction and Application of Microalgae Carbohydrates
This review covers how carbohydrates from microalgae can be extracted and used in health, food, and industrial applications. Microalgae research is relevant to microplastics because algae are sensitive to plastic particle toxicity and because algal coatings on microplastics affect how marine organisms interact with them.
Evaluation of Polyethylene Terephthalate Microplastic Removal in Water System Using Porphyridium cruentum Microalgae
Researchers evaluated the ability of the red microalga Porphyridium cruentum to remove PET microplastics from water through a bio-aggregation process mediated by exopolysaccharides. The study found that while high microplastic concentrations reduced algal growth, the algae produced more exopolysaccharides in response, achieving up to 89% microplastic removal, suggesting a potential nature-based approach for water treatment.
Microalgae as Contributors to Produce Biopolymers
This review examined how microalgae can produce biopolymers as sustainable alternatives to fossil-based plastics, highlighting their potential for generating biodegradable materials like polyhydroxyalkanoates and polysaccharides for packaging and biomedical applications.

This review examines microalgae as a source of biopolymers for sustainable plastic alternatives, evaluating the potential of algae-derived materials to address the environmental and health harms caused by conventional plastic waste and microplastic pollution through biodegradable substitutes.
Microalgae in Bioplastic Production: A Comprehensive Review
Researchers reviewed microalgae as a feedstock for bioplastic production, highlighting that algal polysaccharides and polyhydroxyalkanoate content can be harnessed through blending or fermentation-based methods, with genetic engineering tools like CRISPR offering potential to boost yields toward commercial viability.
Microalgae Polysaccharides: An Overview of Production, Characterization, and Potential Applications
This review covers microalgae polysaccharide production, characterization, and applications, highlighting their antioxidant, antibacterial, and antiviral properties while noting that microalgae can simultaneously remediate wastewater during biomass growth.
Marine vs freshwater microalgae exopolymers as biosolutions to microplastics pollution
Marine and freshwater microalgae were found to produce exopolymer substances that form hetero-aggregates with microplastic particles, suggesting these biological secretions could promote microplastic sedimentation and reduce surface-water concentrations.
Microalgae colonization of different microplastic polymers in experimental mesocosms across an environmental gradient
Microalgal colonization of five different microplastic polymer types was monitored in freshwater mesocosms across an environmental gradient, finding that polymer type, surface properties, and environmental conditions all influenced the biomass and community composition of epiplastic microalgal biofilms.
The effect of microplastics pollution in microalgal biomass production: A biochemical study
Scientists exposed the marine microalga Phaeodactylum tricornutum to polystyrene microplastics and found that both short- and long-term exposure at environmentally relevant concentrations disrupted biochemical composition including proteins, carbohydrates, and lipids.
An ecotoxicological approach towards the understanding of the impacts of micro- and nanoplastics in the marine environment
This PhD thesis investigated how micro- and nanoplastics affect marine microalgae and associated microbial consortia, examining how extracellular polymeric substances mediate plastic-biota interactions and how these effects cascade to higher trophic levels in marine food webs.

Not relevant to microplastics — this paper reviews emerging biotechnology and omics methods for discovering new cyanobacteria and microalgae species and characterizing their bioactive metabolites for industrial applications.
The utilization of exopolysaccharide (EPS) from microalgae Chlorella vulgaris in microplastic removal
Researchers investigated whether exopolysaccharide (EPS) produced by Chlorella vulgaris microalgae can facilitate the removal of polypropylene (PP) and polyethylene terephthalate (PET) microplastics from aquatic systems, while also examining microplastic effects on algal growth. The study demonstrates that EPS functions as a bioflocculant capable of binding microplastics, with implications for biologically-based water treatment.

Evaluating physiological responses of microalgae towards environmentally coexisting microplastics: A meta-analysis
A meta-analysis of 52 studies found that microplastics inhibit microalgal growth and photosynthesis and induce oxidative damage, though microalgae can recover over time. Cyanobacteria are more vulnerable than green algae, and the relative size of microplastics to algal cells governs the mechanism of impact, while aged versus pristine microplastics have opposite effects on extracellular polymeric substance and microcystin production.

Selection of microalgae and cyanobacteria to produce polyhydroxyalkanoates (PHAs) - A case study in Vietnam
Researchers screened 47 strains of microalgae and cyanobacteria from Vietnam for their ability to produce polyhydroxyalkanoates (PHAs) — biodegradable plastics made by microorganisms — finding 15 strains capable of producing them, with several Arthrospira (spirulina-type) strains accumulating the most. These naturally produced bioplastics could serve as a sustainable, biodegradable alternative to conventional plastics that contribute to microplastic pollution.
