Extracellular polymeric substances in green alga facilitate microplastic deposition

Kishore Gopalakrishnan et al.

Summary: Microplastics (MPs) are globally present in sediments and surface waters, and interactions with algae play a crucial role in their vertical transportation and impacts. Research demonstrates that under certain conditions, MPs can stimulate the production of EPS by algae, facilitating biofilm formation and expediting the transport of MPs to sediment.

Single and combined effects of microplastics and lead on the freshwater algae Microcystis aeruginosa

Shan Wang et al.

Summary: The study investigated the single and combined effects of microplastics (MPs) and lead (Pb) on freshwater algal Microcystis aeruginosa. Results showed that Pb promoted algal cell growth, while MPs inhibited growth. Combination of MPs and Pb had a synergistic effect on promoting aggregations of M. aeruginosa. These findings suggest that the interaction of MPs and Pb can have significant impacts on aquatic ecosystems.

Growth inhibition, toxin production and oxidative stress caused by three microplastics in Microcystis aeruginosa

Xiaowei Zheng et al.

Summary: The study revealed that PVC, PS, and PE microplastics had significant inhibitory effects on the growth of Microcystis aeruginosa, impacting its antioxidant enzyme activities, cell membrane integrity, and toxin production. Different types of microplastics had varying degrees of impact on the freshwater algae, with PE microplastics showing the highest resistance.

Comparative growth and cellular responses of toxigenic Microcystis exposed to different types of microplastics at various doses

Qianruo Wan et al.

Summary: This study explored the dose- and time-dependent effects of microplastics on toxigenic Microcystis growth in freshwaters. Results showed that microplastics induced hormesis effect at low dose in early stage, but inhibited growth at higher doses in mid-late stages, with varying effects depending on the type of microplastic. Antioxidant enzymes were activated under microplastics stress, reducing cell damage.

Distribution and sedimentation of microplastics in Taihu Lake

Qiji Zhang et al.

Summary: Research in China's Taihu Lake and surrounding major rivers found varying levels of microplastic pollution, with inflow rivers more affected than outflow rivers. The main components identified were polyvinyl chloride and polyethylene, with differences in average size and distribution observed in different water bodies.

The occurrence and abundance of microplastics in surface water and sediment of the West River downstream, in the south of China

Daofen Huang et al.

Summary: This study investigated the distribution and characteristics of microplastics in the downstream area of West River, revealing differences in microplastic abundance in different land use areas. Microplastics were mainly small in size and fiber-form, with polypropylene, polyethylene, and other polymer types identified as prominent.

Size-dependent toxic effects of polystyrene microplastic exposure on Microcystis aeruginosa growth and microcystin production

Di Wu et al.

Summary: The study reveals that 1 μm polystyrene microplastics have a greater impact on freshwater cyanobacteria compared to 100 nm microplastics, promoting algal growth and inhibiting photosynthesis. Additionally, 1 μm microplastics increase intracellular microcystins content and inhibit their release, while 100 nm microplastics only promote microcystin production.

Effects of polyethylene-type microplastics on the growth and primary production of the freshwater phytoplankton species Scenedesmus armatus and Microcystis aeruginosa

A. Sanchez-Fortun et al.

Summary: The study found that polyethylene microplastic particles can impact the growth and photosynthetic activity of green algae and cyanobacteria, with white or fluorescent blue microspheres significantly reducing green algae cell growth, while blue microspheres had minimal impact on cyanobacteria growth. Additionally, microplastics can alter the photosynthetic activity of these organisms.
