Summary
Researchers exposed marine diatoms (Chaetoceros neogracile) to amine-functionalized polystyrene nanoplastics and found disruption to photosynthetic pigments and membrane lipid composition, with exponential-phase cells showing impaired long-chain fatty acid synthesis at high concentrations — identifying lipid and pigment profiles as sensitive biomarkers for nanoplastic stress in marine primary producers.
The impact of nanoplastics (NP) using model polystyrene nanoparticles amine functionalized (PS-NH) has been investigated on pigment and lipid compositions of the marine diatom Chaetoceros neogracile, at two growth phases using a low (0.05 μg mL) and a high (5 μg mL) concentrations for 96 h. Results evidenced an impact on pigment composition associated to the light-harvesting function and photoprotection mainly at exponential phase. NP also impacted lipid composition of diatoms with a re-adjustment of lipid classes and fatty acids noteworthy. Main changes upon NP exposure were observed in galactolipids and triacylglycerol's at both growth phases affecting the thylakoids membrane structure and cellular energy reserve of diatoms. Particularly, exponential cultures exposed to high NP concentration showed an impairment of long chain fatty acids synthesis. Changes in pigment and lipid content of diatom' cells revealed that algae physiology is determinant in the way cells adjust their thylakoid membrane composition to cope with NP contamination stress. Compositions of reserve and membrane lipids are proposed as sensitive markers to assess the impact of NP exposure, including at potential predicted environmental doses, on marine organisms.
