The proteins encoded by psaA and psaB form a heterodimer, an essential compound of photosystem; while the protein encoded by psbC binds with chlorophyll a in photosystem II, serving as antennae in photosystem. Here we report that a heterocyclic brominated flame retardant, tris(2,3-dibromopropyl) isocyanurate (TBC), inhibited the expression of psaA and psbC, then leads to the decrease of Nannochloropsis sp.'s growth biomass. TBC exposure inhibited the expression of psaA and psbC at 10, 100 ng/mL slightly and 1000 ng/mL significantly. In addition, TBC was found to slow down the growth of Nannochloropsis sp. at concentrations ranging from 10 to 1000 ng/mL. These results indicated that TBC influenced both photosynthesis and growth performance of Nannochloropsis sp.
